- Today we talk about setting up your servo endpoint adjustment (EPA) and why it matters; with "How To" demonstrations with a programmable transmitter, Arrma vehicles with Spektrum STX2, STX3 and DX3, and finally with the Traxxas TQi Transmitter. These principles also apply to 2-Speed and DIG servos in rock crawlers, as well as the Throttle servo in nitro vehicles.
Make life easy with an aftermarket programmable transmitter.

Thanks for the help. You are by far one of the most helpful and easy to fallow rc gurus! Thank you again.
This is a great tutorial.
I can do it in my sleep now.
No more fears of premature servo damage.
Thanks for showing this valuable end point method. Much appreciated. Great video with excellent explanation!
Cody King, dropping lots of knowledge 🔥!
Very informative video. I don't even use this kind of equipment, I'm building a rc-controlled Lego car via Bluetooth and a ps4 controller with custom parts. However, this video made me realize I could do the same thing to save my servo's life, but in the code.
Nice video! Explained well, cheers for that!
Good stuff! I’m gonna recheck my steering adjustments.
Glad I found this....got a 5T that I'm hooking up to a Flysky controller and will need to learn about all this, so i can set accordingly. Thanks for the explenation. 👍🙏
Hey me too just got a 5t2.0 few weeks ago waiting for my Futaba 7PXR to come in! This is my first 1/5 scale so just like you I'm watching endless videos to try and learn as much as I can. Do you plan on any upgrades and if so what kind?
So Clear explainations. Thanks ! (Even on old RC cars without those functions on the radio) :)
Man this video help me out a lot thank you so much straight to the point very simple to understand
VERY VALUABLE VIDEO! THANKYOU VERY MUCH!!!
Another excellent tutorial, many thanks guys!
Thank you so much for this video. I knew how to do this on my Hobao buggy, but had no clue I could do it with my Traxxas cars too. I just upgraded to a single servo in my E-revo 2.0 and have been hearing it screaming at me for help, but didn't know how to do that till now lol.
Or you can get the Bluetooth module and download the Traxxas link app and eliminate the buttons also get the Traxxas phone mount you
You can set your end points and everything else in the app and there’s a lot more to the app
Thanks for the tips Brett ! 😎👊
This is great thanks for the easy to follow instructions
This is what I was looking for thanks!
THE BEST VIDEO EVER EVER AMONG ALL TO SET THE ENDPOINT, THANK YOU VERY MUCH YOU ARE THE BEST, really this channel brings joy to my life especially im new to the hoppy ❤❤❤
this endpoint adjustment really really important great tips, my servo already stuck and broken, because im not concider about this EPA, next time i will do like this step, thanks admin
Perfect timing my Xmaxx and revo servos just went out 👏
Perfect timing would have been before you’ve ruined them.
@@billybobbobson5346 stock servos went out they are set up perfect
Great video! Dropping 💎
Thank you very much for doing this. It worked too perfection
Excellent. Happy the video helped William.
-Brett
Thank you so much! It was a great help to save my SERVO ;-)
Thank you that was really helpful
good video hopefully this will help people
Another well produced and informative video. Thanks Brett.
This is a really good how to video, nice
Had some hopes for my TQ transmitter, oh well, but I will try to adjust it with the hole position on the servo horn, hopefully works.
Good job, very helpful 👍 Btw, the end points on the STX3 CAN be set independently, using the multifunction programming. Most people dont even know it's there and the instructions are pretty vague on how to do it properly.
Great video! I am going to do this asap.
OMG......
THIS WAS SO GREAT 👍
Thats what i did when I got my jlb 21101. Nice car. Hoping to get a arrma kraton v4 or a e revo 2.0. BTW love the hobby. Love from India. Keep safe. Keep bashing.
Greetings!
-Brett
Excellent, very good job.
Thx this saved my rustler!
awsome advice thanks alot
I always have set my endpoints with the hum of the servo, dial it down til the hum stops
That’s how I’ve done it
Same bro
Same
Yup
Thanks for the tip!😁
Good job liked the video alot thanks for sharing.Stay Safe Stay Healthy
Thanks Mar, you too.
-Brett
And here I am with a vintage Super Hornet and an Attack 3 transmitter. Hope that Futaba servo doesn't have a bad time.
Killing the game, Brett
Great video & info thanks for sharing happy bashing my friend👍🤙😎😛😜😝👊✌
Amazing! thank you!
very helpful, thank you
Thank you so much dude, I have this issue with my upgraded stampede where the wheels turn so far that they rub and lock up on the arms, Thankyou so much
Great video
5:14 is for traxxas
Very good !
I'd like to see you do a talk on front wheel drive rc cars.. motors. Steering. Tyres. Etc..
Hey you guys forgot to mention that for 4wd cars sometimes the wheels will turn further than the driveshaft can freely turn. The car will steer freely when stationary but if you put your hand on throttle it might start binding. I’ve cracked my shafts like that
Great tip! Thanks for adding that.
-Brett
@@AMain_Hobbies will you be doing the wishlist thing this year too?
@@jasonbell2733 I don't know for sure but probably.
-Brett
So dont do it like this then..(felony) I upgraded my servo and its stressing..
Thanks!
I'm so glad my wife and i got rid of our Arrma and Traxxas transmitters.
Good call. A good programmable aftermarket transmitter is priceless and can be used with all your future vehicles. What transmitters did you get?
-Brett
@@AMain_Hobbies I actually went for the under dog... FlySky Nobel. And oh my goodness am I impressed. My entire fleet is tied to it and the response, the range, the fine running, and the features are amazing! Well worth the investment in my opinion. Its even set up for boats on a separate setting!!! Highly recommend!!! But be prepared to shell out $260 for the transmitter and $40/ receiver.
I need to set my epa on my Xmaxx since when steering to the right is scraping against a screw in the lower suspension arm
Excellent video. Is it possible to extend the maximum turn of the a servo? A have a pan-tilt camera in my rc and it didn’t turn enough.
Nice 😎👍🏼
Can you do a video on erevo 2.0 dual servo adjustment?
Im assuming once you set the angle on your controller you can't use a different controller after ? Or that will reset the angle?
How do I adjust the steering rate on the dx3 w avc?
how to set up end points of microservos, if i want to change my stock TRX4 esc into Hobbywing?:(
You said “Robust” ... Hehehe!
Grazie mille per questo tutorial..ho comperato un Arrma Granite le ruote anteriori sono troppo sterzate come posso regolare lo sterzo?
Well I wish I had watched this three hrs before running my xmaxx with a new savox after the stock one died then the savox died in half an hour. So I may have not had epa set correctly. But I’m assuming the stock from out the box was already set , the 2850 suck!
Me and my 4x4 slash drive shaft both thank you 😂
Thank you for the informative video!
Will the servo stay calibrated once you bind the receiver to a different remote from the one which you used to calibrate it?
Hmm, never tried that. Since the transmitter is saving those settings, they should still be correct the next time you add your receiver and rebind it to the transmitter, but I don't know. It might not work correctly, it's tough to say. You might have to try it out. When you remove the receiver and add it to a new model, be sure to use a new model profile on your transmitter so you don't overwrite the old settings. Let me know what you find out.
-Brett
@@AMain_Hobbies Thanks a lot, very helpful! 👍
On my Traxxas TQi with Traxxas link i adjusted it with the App.
Well how to set them when my controller is very common and does not have those cool electronics ?
Wow! On the Traxxas TQi I run it seems to require a code mastermind to get all of those buttons mastered! I’m only kidding, but if you have the Bluetooth device installed could you do the same through the vehicle setup? I’ve yet to get the Bluetooth module but it seems to be geared towards that exact sort of thing. To do all of these setups and servo abilities easily from there. Since I’ve not yet obtained the module, I cannot say, but I’ve seen the app and from just browsing it I’d hope that I could do that and more through it. Thanks for the advice! I’m sure it will help!
Yeah, the Traxxas Link makes these adjustments super easy. It's a great device to have and one of three items in our 3 Must Have's for Traxxas: czcams.com/video/_wegSAKX-3A/video.html
-Brett
I just bought an e revo vxl brushless and after testing the steering function which worked just fine, the servos started binding. I have had it for about 24 hrs and haven’t even got to enjoy it. Is there something I can do that I may be missing? Does this happen frequently ? Other than owning two drones, I am new to the hobby grade scene. Thanks for any advice! Your videos have been part of my research base to get the e revo lol
Hey Daniel. How would you describe the binding? With the truck on the flat ground, are the tires turning? Sometimes a rock or debris can get wedged in the steering linkage causing issues.
-Brett
What do I do if my trx4 sport is binding when it is turned all the way to the left or right? I can’t set EPA with the sport transmitter
Do your best to avoid using 100% steering throw. Other than that, you could upgrade your transmitter.
-Brett
Hello. In my spectrum dx3 I can't obtain full end points stering. Why? I have Losi 5t. Turn left . turning left I get the maximum but turning right is missing the scale on the rc remote and I do not get the maximum. While by hand, I am able to turn the wheels even more to the right. What is wrong?
Is this when you are trying to set the end points like in the video, or when steering normally?
-Brett
Nice video and very helpful as I am looking to upgrade my stock 3kg servo on my FTX Outlaw to a 25kg one. Will this work on the Flysky GT2?
I don't think they do, although i'm not that familiar with those transmitters.
-Brett
@@AMain_Hobbies Thanks. Is there any way to do it on transmitters that are like this, or do you have to buy another transmitter and does the Flysky GT3C have EPA or an EPA like setting to set servo EPA.
One of the How to's to keep....
My gosh, I just got the Traxxas 330 servo It sucks!!!!. The horn Won't center align right after I took my Rustler 4x4 vxl 4 times. Endpoints are set properly but it still wines loudly. My gosh, it won't even turn my wheels fully unless the car is moving sometimes. I'm gonna batter and deep-fry this servo if it gets worse. (any reliable servo suggestions for 2.8 HP tires besides the eco power 120T?
What about drift cars that have wide angles like Yokomo YD2S or the 3Racing Sakura D4?
Those vehicles are designed to have more steering angle than an average vehicle, but the end points still need to be set.
-Brett
I don't understand how to set that EPA on my Carson Reflex Wheel Start transmitter...
I don't quite understand the manual, I can't tell if it's explained or not (poor english)
Please, help me guys😢
I just got a new standard size analog Hitec servo for steering and it makes that "overextended sound"(1:51) at all times, in any position, even without a horn on it. Is it a defective unit?
It's hard to say, some servos are just noisy. But if it's still noisy when there is no load on it, then that's just the way it is.
-Brett
The case doesn't seem to be getting warm or anything so maybe it'll just run this way for a long life LoL. It was among the cheapest Hitec has to offer and still seems stronger and is definitely faster than the stock RTR digital servo it replaced. Can't hear a thing once the nitro engines fired up XD so I'm just gonna send it. Thanks for your reassurance! and all the parts and supplies!
I have a Arrma SLT3 transmitter and receiver that I pulled from my 3s Granite. I have the Steering Rate maxed out and still don't get enough travel. Is there a cure for this? The servo has a 180 deg. control angle.
I'd look elsewhere for an issue; maybe the steering assembly is bound; maybe the servo saver is worn out; maybe it's just a limitation of the car?
What car is it? What servo is it? What type of servo saver is it? Did you add any other steering or front suspension upgrades?
-Brett
@@AMain_Hobbies I know the steering rack is worn out and probably should be replaced to reduce play but there is no binding. I think the servo saver is the problem now that you mention it. The servo is a cheap E-Bay special ( FeeTech 35KG )and I have the same ones in my Typhon and Granite. Maybe I should remove the servo and check the travel. It just seems like the AMP never did have a good turning radius compared to something like my DR-10. I totally appreciate you helping me out and feel honored that someone from such a well know company would take the time to answer my question. 💯💯
Hi there!
Im a newbie to the hobby.
Just bought an hbx 16889a pro, running it for a couple of days then all of a sudden the steering wont turn at all. But the throttle is fine. Rc is still running its just the steering wheel is not responding at all.
Can you please tell me what to do?
Should i just replace the servo with a new one!
Thanks!
Is the servo moving, like it's trying, or is it completely unresponsive? Is the servo wire seated into the electronic board ok?
-Brett
@@AMain_Hobbies so i have two hbx rc’s.
One rc is completly unresponsive. No movement at all when it comes to steering.
The other rc is responsive, the servo is moving but its like restricted and it cannot turn the wheels. Both rc are ok when it comes to the throttle. They can run forwards and backwards
but how do i change my stearing angle with a wltoys controller?? plz answer i really need help im breaking my car
If it doesn't have an EPA setting, does it have a dual-rate knob? It might be labeled "D/L"
If you turn down the dual-rate, that will limit the steering travel for both tires together, where EPA does the left and right side independently, but at least it should help save your servo if its overextended.
-Brett
ftx torro nitro how to replace upper front steering plate any one know how to do it cant find any video unless any find one or no how do it let us know any help much helpfully not the same in video it Nitro one
Does it matter if the car is on or off the ground when setting EPA?
It's best to have it at normal ride height on the ground. Good question.
-Brett
How do I change the OE Servo in my Maxx truck to a 2085x Servo? (MAXX Truck)
Just remove the old servo, and install the new. It's a direct swap. Remove the brace above the servo and you should have direct access.
-Brett
What about the throttle/brake epa ?? I have a blx 185 and the brake percentage is all the way up but the brakes are terrible, but only on one of my radios....any advice ?? Has been calibrated properly etc
Hmm, not sure about that Michael. When you say the brake percentage is all the way up, is that on the transmitter or the ESC?
-Brett
@@AMain_Hobbies hiya Brett thanks for the reply...both are turned up well the end points on the controller and the brake percentage on the esc...can only set it to 50% for some reason in those....its baffled me so I think I'm just going to get another max 6 and I'm not sure whether to get an ezrun 4274 2200kv or a xerun 2250kv, which would you favour over those 2 please...looking for speed and low temps
@@mickyovts3872 For just bashing around, probably the EZRun because it's less expensive yet still high quality. If you are racing the Xerun would be the better option. Hope that helps!
-Brett
I have the TQI Transmitter for my Xmaxx. I followed this process step by step. However, when I make the adjustments, the setting does not save and it still over extends to the left. Also, my transmitter has 4 blinking red lights when I follow these steps to enter end point programming mode. Anyone have any insight or similar issue? I did everything exactly how this guy did.
I have the same issue
@@nopeairsoft469 Are you burning through servos too? I've burned through 3 already. One stock and 2 of the upgraded servos.
Can someone help? I have a traxxas Ford gt, when I drive it wobbles back and forth, I believe the servo is swaying
Sounds like the servo saver parts, give them a check! They wear out over time and stop holding straight, so the car will wonder.
-Brett
Is there a way to adjust steering trim so the knob is centered on the tqi? To go straight i have to clock it to the right. I adjusted the servo horn and I can't get it perfectly straight. I either have to clock the knob to the right or the left. Is it possible to reset the steering trim to center?
Usually the knob is not centered because the servo is usually off center a little from where the vehicle is. You can't reset steering trim per say, but you can adjust sub trim, which is like a more precise trim to use, before the actual steering trim. Go to 5:34 in the video and look at the program tree, and notice directly above the end points, is sub trim.
Hows the servo saver in your vehicle? Sometimes when they start to wear down, the steering gets sloppy and doesn't center. When driving, it feels like the car just steers where it wants to, like "wandery".
-Brett
@@AMain_Hobbies thanks for the reply. I'm kinda new to the sport. So what does the sub trim do? I did what the traxxas manual says and I'm not seeing any changes.
Hey, you're welcome@@jadebylund7061. Here is an explanation copied from the TQi manual: The Sub-Trim function is used to precisely set the neutral point of the steering or throttle servo in the event that simply setting the trim knob to “zero” does not completely center the servo. When selected, Sub-Trim allows finer adjustment to the servo output shaft's position for precise setting of the neutral point.
This might help you center up the servo without maxing out the knob on your transmitter. What vehicle do you have?
-Brett
@@AMain_Hobbies is on a rustler 4x4 vxl. I just changed the servo out after the original died. I've had it 3 months now and the servo savers still seem okay.
Hi would you be able to tell me what is steering dual rate mean please. Does it mean end point
Steering Dual Rate is similar to End Point Adjustment, except steering dual rate effects both left and right side equally when adjusted, and End Point Adjustment controls the left and right side independently.
-Brett
@@AMain_Hobbies thank you soo much. I really appreciate your help 🙏
How can you set end points with the old analog transmitter?
Does it have an EPA adjustment knob? If not, you probably can't sadly.
-Brett
@@AMain_Hobbies Ok thanks. I don't have that.
Shouldn’t you keep the wheels off the ground? I’ve always done it off the ground.
nice haircut ;-)
Can someone tell me how to do it with a stock xp130 transmitter?
Unfortunately you can't set the left and right independently, but you can back down the throw as a whole using the steering dual-rate knob.
-Brett
Hello,
So I just pretty much just built a B74.1D. I have a 3PV Transmitter.
I just wondering if my EPA sounds proper to you.
So I have the Trim set to R 45. its the best I can get it..
I adjusted the EPA per your fist part of the adjustments the Aftermarket Transmitter..
So the L is 60 and the R is 84.
Its seems kind of ODD the right is more extreme then the left?!
I Built the Car to Spec. I used a Digital Calipers.
Im wondering Does this sound Right?
Thank you
John
The number values are not really significant and you will always have one side with a higher value. It does not mean one side has more steering, it just means one side needs more servo throw. As long as you set your epa's correctly, the mechanical parts in the steering assembly will receive the correct amount of servo throw to achieve maximum steering angle (that amount of servo throw can vary side to side).
It sounds like you have correctly set your epa's. Hopefully this makes sense. Have fun racing!
-Brett

@@johnm8558 John, I just got done telling you the values don't matter. All that matters, is your servo doesn't try to overthrow the limits of the mechanical steering system. Please, watch the video again.

@@AMain_Hobbies I support my local rc shop when I can.But when I can't AMain is where I always look. Next on my list is a axe 3300 system for my trx4 sport!
Brett in your video for the Traxxas EPA setup, was the steering trim knob supposed to be all they way counter clockwise and not set to 0? I thought I saw in some other videos and thought you said you want to make sure the steering trim is set to 0 before adjusting your EPA, so just was curious before I swap out my servo in my Maxx since I think the stock servo is shot.
You'll want to center the steering so the truck goes straight before you set the EPA's. When installing a new servo, you'll want to completely center the servo when you add the servo horn. Sometimes I'll put a horn on the servo and turn it untill I see where the horn needs to be, and then adjust by picking up the horn and reinstalling. Once i'm good, screw on the horn. You can also turn on the model and let the servo center (but be sure to set steering trim to 0 for this). Once you get the servo installed, turn on the model and center the steering with the trim knob so the truck drives straight, then set your EPA's. Hope that helps Donnie!
-Brett
@@AMain_Hobbies Brett I think in understand, I will take a try at it tonight and if I get stuck I will message you back. But sounds straight forward but we will see if I get messed up when actually doing it. Much appreciated as always.
@@DonnieKluck You got this Donnie! Let me know how it goes.
-Brett
@@AMain_Hobbies Brett I got it installed question I have is when I turn the when to left or right when I let it go it doesn't go am the way back to center. Not sure if it is just tires gripping the floor but just seemed odd why it wouldn't bounce back to straight (it is just off by a bit but you can definitely tell not straight)
@@DonnieKluck Hmm, most likely the servo saver in the steering system of the maxx. It's the two plastic pieces on the left steering post. Unfortunately, they're not adjustable, so after a year of use or so they should be replaced to get back some steering precision. After use, the two pieces slide on each other with dust and grit, and they sand each other down, making slop. This is my guess, there is no other reason it. Checkout those pieces. I think we talked about it in the Maxx upgrade video.

What’s a good upgraded servo for arrma notorious 6s v5 blx
Anything with lots of torque will do the job, and then maybe waterproof if you need that. This WP250T is a good waterproof option: www.amainhobbies.com/ecopower-wp250t-waterproof-mega-torque-metal-gear-metal-case-servo-ecp-250t/p1466471
This savox is not waterproof, but a little more powerful: www.amainhobbies.com/savox-sb2290sg-black-edition-monster-torque-brushless-steel-gear-servo-sav-sb-2290sg/p536890
And this 1K TBL is the big daddy for power: www.amainhobbies.com/protek-rc-1ktbl-black-label-ultra-high-torque-brushless-waterproof-crawler-servo-ptk-1ktbl/p1331854
The first servo is probably more than enough for your truck and what I'd pick.
Another component to think about is an upgraded servo saver. Stock servo savers are often set loose and spongy to protect the weak included servo, but with the downside they can absorb some of the steering instead of putting it down to the tires. So a good remedy, as long as you have a more powerful servo, is to use an aftermarket servo saver that you can adjust, and then tighten it up a little. In some cases, you notice an improvement in steering response immediately.
-Brett
@@AMain_Hobbies thanks
The traxxax setup doesn't work on Bangood servos....only sets it for the left turn.....right turn slams all the way into wheel and left side goes like half turn.....press set button twice to reset to full throw on both wheels.....just have to under steer when driving my nitro rustler.....ugh
Did you try resetting the steering trim on the transmitter first? Shouldn't matter where you bought the servo.
