I've been guying futaba since way back when I first got into rc, when you pay the premium it's not just for the torque, it's also the quality and durability I've always been so happy with their products
This is one of the best RC channels on CZcams. Contributing real information to help hobbyist. Keep up the good work Francis Cebedo.
One thing I didn't mention is the Futaba at 8.4v was running out of amps because of the 10amp limit. Thus if we had a more powerful power supply, it would pull more oz/in of torque. Probably hit 1000+.
You can see it as the red light goes on and the voltage drops.
I love watching these servo test it really helps me narrow down what servo I want with the money I wanna spend. Thank you for these videos.
Glad to hear it!
I love these videos. So much info packed into one video! Helps out alot.
After watching some of your testing videos I ended up finding a good deal on a MKS HBL550 X5 servo and I put it into my X Maxx and seems to work awesome so far!!! Thank You for these videos!!!!
Holy Hell! What a servo! Thats insane! Mega Overkill! Such a whine under load! You should Test the Reefs RAW 500. I know you have tested the 555 and 444 but the RAW 500 is extremely popular because you get an upgrade from a coreless servo to a brushless one, and it is 7-seal "submarine" waterproof rated. plus it is nearly as powerful as the 555 while being much faster. Everyone I know putting good money into servos is going for the RAW 500 in extreme bashing setups such as 1/8 Arrma Kraton EXBs. They assume that because testing has been done on the 444 and 555 that they can trust the ratings of the RAW 500. Also, another interesting test from Reefs would be the 400SC Racing Servo. It claims to have absolutely insane speeds while also having enough torque to easily power a 1/8 Truggy around the track and they are getting incredibly popular in the racing scene for their reasonable price and programmability. A good competitor test for these servos would be the Protek RC 170 SBL and TBL servos as they have been extremely popular for many years already and existed before Reefs RC even existed as a company.
Your content is under appreciated. Its really solid.
I appreciate that!
Very nice review! Always interesting videos
When we learn something, you learn something. This one surprised us.
I am currently using the Futaba CB700 servos in both buggies and boats, and absolutely amazing performance and durability. Top quality product.
I have two Futaba CB700 for 1/8 scale on road nitro GT/GP for their superior speed. Those are so powerful the first time set up has to be very careful to not cause damages to the vehicle. (dial down end points first.)
When you gave the much more powerful A700 10amp with constant 8.4volt, it felt like the rig could give away any moment :-)
Thanks for these tests. I need to change my noisy Savox 1272sg in my SCX10.3 (recycled from nitro buggy) for something much quieter...
Saw the flex on the first pull and thought, that isn't going to read accurate, glad to see you caught that and brought it up! That first pull w/o that flex I'm confident that sucker would of hit 1k.
Those are some pretty good numbers on that servo, I'm impressed.
@RC Review Love the servo test videos, very valuable data for consumers to make informed decisions and much appreciated!
When are you going to test the Hitec/RCD DB777WP & D956WP servos? Both look great on paper, it would be great to see test results and hear how they sound under load. And AMain carries both. Hopefully soon?
Thank you again for your time and expertise! :)
Great video sir. Couldn’t remember if u reviewed a protek black label servo yet? Curious how they stack up. Most people agree that they are one of the best, if not the best all around. Appreciate the videos and time u guys put in. Thanks sir and have a great weekend.
well now in 2022 the Hobbywing platinum 130a with the super BEC does 10amps continuous and 20amps peak . This is for helicopters and airplanes. It also goes up to 8 volts.
Nice servo....
I love your channel! I like the way you test the servos! There is some controversy about a similar servo, the cb700(related to the a700), people claiming it consumes less power, but futaba warning not to use with a bec. Maybe you can test? I also saw from your previous test the hitec 9380, incredible low amp draw at stall( around 2 amp). Did you need to use the hitec PAD when using the 9380 in your rc’s? Maybe you can test the regenerative braking feature in the future......
You should test with a power supply with higher current limits. Your supply is hitting the current limit which limits power.
Maybe I missed it but have you seen or done a review of the servo that Beeftubes is selling? I think the number is BT663MG? I recently purchased one and it works great but other than power and speed there's no information beyond that. It will supposedly do 663oz.in. at 7.4v which is where I have it set and it works very well and it's pretty quiet. I'm glad we have guys like you out there that we can actually get responses from, so keep up the good work and again, great video.
That's a monster.
It will basically lift a 60 lb weight off the ground.
Good test but a BEC's current rating is not "what it puts out", it is the maximum continuous current it can handle without overheating/shutting down or simply not being able to hold voltage. So a 5A rated BEC will be able to handle roughly 10A for a short period of 3-5 seconds for example. In a car with just one of these on steering you would get away with a 5A BEC and you would still get the full 70+kg/cm of torque from the servo, although you wouldn't need anything near that even in a 5th scale monster truck!
Hi will u test the CB700 servo in the future as it is for crawler servo thanks
nice video i enjoyed the show ....so im certain im hearing you right the reefs triple 5 will out pull the 777 direct drive ?
That would be an interesting comparison
Hi, is there a plan to test Boom Racing Python black servo in near future?
Imho Futaba makes excellent products .
I just spent £300 on 3x BLS173SV for a Kraken 580 and I thought that stung. Imagine investing £1000 for the servos alone... Some impressive performance, but you're going to have a huge, heavy model to require this much performance.
Please review the new Power HD40 vs the famous Power HD25.
Like he will obey you yeah right.
Wow impressive
Hello Francis! I’m here again! Been busy making videos for my channel! But if you did not see my comment in your last video, I loved it to say the least. 👍
Stop fishing for views.
@@danielkonrad1444 I’m not fishing for views. I’m just trying to get Frances to check out my channel. I really like his, so I want him to check out mine. I only have like 24 subs, sooooo, I can spread the word about my channel.
How is it built Brass bushing on servo pins or bearings and what size gear pins . All steel or aluminum.
Man, this servo will rip the threads out of the rodends on the steering links and panhard.
What rig are you going to put that monster in?
5:47 so why arent you rotating the servo the OTHER way pushing down, the way it was calibrated?
Yes I’m set I have 3
Now I’m curious, I bought the reefs 777, they had claimed it was the most powerful servo on the market I had thought
Wow...
So what is the difference with say a reefs 777,888 or reefs raw 500 and these super expensive futaba servos? I have reefs in all my cars including my touring ravers and all the guys I race with rub futaba. Why?
I was looking at these but they aren't waterproof anyway to waterproof them easily
Reefs Triple 7, please.
A real power servo. But 250 dollar is a lot of money. You can buy a lot of other nice upgrades for this amount of money.
You should apply the weight one inch from the centre of the arm bolt
Yes, that is exactly what we do since that's the definition of the oz/in measurement. We see some other folks though measure from a random arm hole.
@@RCReviewChannel please try to test AGF servos next ... heard their servos are monsters
I'm not sure why a RC crawler would need a servo with this torque. The price point is high. I use high speed/torque servos in my 60CC RC planes and helps. But they are controlling huge control surfaces. I'm using a reefs raw 500 in my SCX10III which, I think may be overkill. A very good review.
Great insight. This servo delivers the goods, that's for sure. Whether one needs it or not, is a whole other issue. Certainly it's good that it doesn't need special direct power wiring and it delivers pull after pull consistently without fading. It will probably operate at 50% of capacity usually so it will be just purring along, staying cool.
As for getting a servo that's this overpowered, it's like most things in life like a 600hp car or a brushless motor running 3s or 4s. It's to impress your friends and sleep better at night. :)
@@RCReviewChannel right on point👍
Hi I love your videos if you can could you do more videos on the cheep rc cars I love those videos
i have an a700, and i chucked it in my x-maxx, and idk why, after a while it got super lazy and didnt have much spsed and torque anymore:(
If the servo tries to pull more amps than the BEC can output won’t you risk burning out the ESC?
Or The Servo Just Runs weaker....
German Big That’s kinda how the video made it sound. But current is determined by the load. It’s my understanding that if the supply can’t handle it eventually it will be damaged. You’d need a BEC that can supply whatever current the servo demands.
Could cause receiver brown out?
They are measured at the spline so likely if you put it at the first hole it’d be closer to the figure, correct?
For oz/in, they are measured 1 inch away from center. For kg/cm, they are measured 1cm away from center.
@@RCReviewChannel where is this from?
Jon Thomas right in the units.
Hey brother what is your link to go online to buy products thanks great view
In the description
In the description, you use the wording "best for...." when what you mean is most torque. Not the same thing eh. Apart from that, good job, thanks for sharing.
thanks...i did not see 1000 ...my super500...8.4v 6a...pulls at 50cm...10kg...new, price??? 125
Any black friday deals?
This is a giant airplane servo not sure how well it do in crawler. If anyone remembers reef made a 999 special edition it’s all about gearing to get that torque
@@themountain59 you hate reefs enough to reply to every comment mentioning them, lol.
I was there
974oz/in at 84watts vs 735oz/in at 140w. looks like a monstrous bone breaker
😧 I think I predicted 648 at 7.4! Nice, Futuba.
Shouldn't you be using the CB700? This is (in theory) the aircraft servo rather than the car servo.
I am curious about this also
Your probably not going to get that much torque from a Model in real life usage so the amps usage of the servo will be a lot less especially on large scale 3D Airplanes. But good to test max draw and torque. The smaller Futaba and JR servos I tested had really low amps usage as compared with other servos like Hitec and Savox but I still prefer those over Futaba and JR as there better bang for the buck!! We tend to overpower our plane batteries anyway.
Check out my tire mod!
Air in the tires
It would be different if they still made product in Japan, but they don’t. They shouldn’t be charging this much for a servo, but Futaba purists will still buy this, just like Airtronics/Sanwa purists buy their stuff.
🤤🤤🤤🤤
What you're really gonna get if you run this servo hard off a 6V 5A bec is some black smoke.
The scale says 110lbs/50kg Max. Won't that make the results inaccurate? 🤔
It's within range. 1000 ounces is 62 lbs.
The kg/cm is a different measure, measuring kg 1cm from center. We're measuring 1 inch away from center and doing a conversion table here www.convertunits.com/from/oz-in/to/kg-cm
InternetS ????
i believe it's called interwebs
You get what you pay for - Futaba quality
Impressive but too much money for me. Im happy with my HH
I was gonna buy 2 of these but I’d never buy a servo that makes that noise. Horrible .i really like the agf servos but the price has tripled now everyone knows how good they are.
I also hate the noise… but what can you do? Savox, Futaba… all soooo noisy.
@@WasNiksIsNiksWordtNiks I bought an agf servo and it is totally silent. I expected all brushless servos to be silent. Maybe it is because he strained it so much!?.
@@neontetra1000 What model did you end up buying if I may ask?
@@WasNiksIsNiksWordtNiks I cannot remember the model number but mine are the original low profile one all alloy
They are now rebadged with different graphics for touring car
Mine are plain black and were only about 40
Dollars each when agf were new to the market. They are still Great servos . I will but the full size One next for a new 1/8 e buggy
I'll buy the reefs 777 for $148 before this one . And it pulls more oz/in of torque.
Reefs 777 for sure. Futaba is crazy charging 250 for a servo. Whats crazy is they have a couple of servos that the charge 200+ for.
@@themountain59 alilibaba doesn't have any servos with 1000oz of torque.
OK I've been out of the hobby now for about nine years as I went completely blind in a big heavy vehicle 1/6 of 1/5 scale I understand you needing this much torque maybe however almost 20 years ago I bought a JR 8717 servo it had a rating of 188 ounces and a speed of I think .08 around that I have ran that servo in an HPI savage fairly heavy vehicle, an electric Losey buggy and an electric team associated Trogi. I have never seen the need for a faster or even stronger reacting servo And it only 188 ounces. I don't understand why these new servos have to have 350 400 ounces and then recommend that servo on a 1/10 scale vehicle it should not take nowhere near that much power to actually turn a 1/10 or 18 scale vehicle, I just don't get it
First?
Nope nope nope to Much money
I'm not seeing $250 worth of results here.
Just screaming lies. Man that's loud
Complete overkill for 99% of RC's.
Do some reviews on cars , that stuff is boring.
Quiet you. This quality RC info for RC enthusiasts. That’s all we need is another channel to upload their opinion of the same regurgitated review of a rc car.
