- This is my second & third attempt at a top speed test for the @poorboysrc Tamiya TT01 / TT02 Speed Challenge 2023, many thanks to Fil for laying down the gauntlet again this year. There are now 2 classes in this competition, one for brushless 2 & 3S LiPo cars and the one I'm entering, brushed motors and 7.2v NiMh batteries.
In this video I run both the Core RC 15T brushed motor and the Absima Thrust Eco 15T motor - can I break the elusive 30mph barrier?
Many thanks to my mate Rob @robbrennanrc for the help and filming of this speed run attempt. Also, many thanks to Craig @theoagrc for sending me the Schumacher Contact foam tyres and wheels, what a star! You can see how the TT02 does on the foam tyres at the end of this video. And finally, many thanks to Peter @cw-01creations46 for donating the Core RC 15T motor, cheers, Peter!
See attempt #1 here: • Tamiya TT02 Speed Test...
My TT02 spec for this run:
18T Absima Eco Thrust brushed motor
Mtroniks Trident XT-12 brushed ESC
YEAH Racing alloy motor mount
ball bearings
oil CVA shocks
alloy propshaft
22/64 gearing - Auta a dopravní prostředky
Great runs, Mark. And the banter between you and Rob is stellar as always! The elusive 30 mph is riiiight there, who will get there first, you, or Craig??? 😉💨💨💨
Appreciated, Fil! Well at least rob and me try to have a bit of fun for the camera, he's a right cheeky so and so! I'm determined to get past 30mph, but we will have to wait and see if Craig gets there first! Cheers, dude! 😎👍
@@MarkBryanRC you guys get us all laughing, and really add to the challenge. So stoked to have you both here! 👍🏻
@@poorboysrc Glad to raise a smile, Fil! Yeah, we are both stoked to be involved, what a ride it is so far and we've only just started!!! 😜👍
@@MarkBryanRC still 7 weeks to go, brother! Looking forward to the nonsense, laughs, and silly speeds! 😜
29 again Mark!! You just giving me chance to catch up pal?? Glad those sabotage foams I sent you are slowing you down… 😂 Seriously through you are welcome pal and I am sure they will come into their own as the power continues to increase. Onwards and upwards matey… there are still more motors out there to be had!! See you at 30 🚀🔥
Sabotage tires!!! Hahahaha!!! You play dirty, Craig. I love it! 🤣🤣🤣
@@poorboysrc 🤪 Anything to win pal
I know, I'm gutted, mate! I was so sure the 15 Absima would do the trick, the stats on the motors should mean it's a few mph faster! I tried a few more times off camera, but still no success!! 😭
Blimey, sabotage tyres!!! 🤣😜 Never considered that! 🤣
Yeah, they need to be warmed a bit before they grip. Well I've only got 2 motors left, already tried one and the other is in the post. After that it's gear ratio time! Take it easy, dude!
Haha, yeah Fil, what is he like?!?!?! 🤣🤣
@@MarkBryanRC I found the warm tires helped a lot! It would be nice to have a sacrificial battery for tire warming, then switch to a fresh pack for the Speed Run.
Be careful of that Craig... He's coming for ya! Haha! 😉💨💨💨
Good runs Mark this challenge is so much fun love watching all the videos and working on mine
Awesome! Thank you, Brent! I got my fingers crossed for ya, dude! 🤞😎👍
29 but still in the lead. Maybe before your next run you'll should bribe Rob to say 35🤔😉😁
Yes, but I don't think my lead will last long, Dirk! I need to up my game, and FAST! Haha, yeah I need a "cheating" cameraman!!! 🤣👍
@@MarkBryanRC that's easy meassire kmh and pretend it's mph. But I hadn't said it🤣🤣🤣
@@RCBirds Very funny, mate! 🤣🤣👍👍
Haha great vid and run bud, good stuff...😎💯💢👍🤙
Thanks dude, glad you enjoyed it! Onwards and upwards! 😎👌👍
So still 29... Seems like 30 is the sound barrier here....
Great effort. Keep your camera man Safe 👍😁
Thanks Tom! You are spot-on, this 30+ malarkey is harder than it seems! Got gearing to play with though after the fastest motor is selected, so I'm sure I'll get there! Cheers!👍
29mph Rob you cheeky bugger! 😂
No way!!!, I'd be throwing a 5.5 turn brushless system in it with a gyro and send it to the moon or its dusty grave!!! 😠. Hope you feel better Cobber and all the best mate😁🦘🇦🇺
What is he like, mate! G'day to you and thanks for being here!
I'm not going near a brushless setup after I tried to film Rob with his 48000kv and 3s!!! Video coming soon!!!
I'm still sore about this stalemate situation of 29mph! One more motor to try and then it's time to gear up the fastest of the bunch. Cheers, Cobber! 😎👌👍
Great run, well done
Thank you dude! 👍
That was great to watch, Mark! Although not beating your PB, still got some valuable knowledge in the bag!
I'm guessing between those motors, now you need to figure out which one has most RPM AND most torque, because you will need some oomph when you up the gearing. Ha ha, a bit more factors to factor in!
I'm beginning to get nervous, as I noticed yours was a bit less stable in this run, I need to hurry get mine built as I realise I have never driven one before, I need to learn from scratch, ha ha...
Have a great rest of the weekend there, mate!
Hello my friend Mads! You got that right mate, got 2 motors to test and then I'll choose the one to go forward with. Looking like the first one I tested might be the one! Yeah you need to get up and running so you can get a feel for the chassis. Can't wait to see what you think! Cheers mate and hope Sunday is going well! 👍
Nice passes 👍 good luck 👍
Thank you Sir! you too! I got some catching up to do! 😬👌👍
The joys of trying to out do each other, if that 15t thrust was brand new it maybe have been a bit quicker ? Might have to start playing with gear ratios soon ;) it’s good fun watching you and Craig go for it, take care mate
My thoughts exactly, Andy! Yeah the friendly rivalry with Craig is really making this challenge more fun. I have one more motor to test and then it's on to the gearing. Fingers crossed! All the best and take care too my friend!
Nearly mate, 29mph still good tbh thanks for your upload 👍🙏🐱
Thanks Cat, yes I feel like the "nearly" man at the moment! 🤣But I will not give up! Cheers mate and have a lovely weekend! 😎👌👍
😂😂 you pair are so funny 😅. Never mind Mark 29 is really good 👍. Take care 😊
Thanks Kim 👌 😊 Yes 29 is OK but I really wanted 30!!! We will get there mate! All the best and have a great weekend! 😁👍
Great run
Thanks Thad! Look forward to seeing yours! 😎👍
Fun times while working for that goal!
Great stuff fellas and 29mph is impressive!👍😊
You got that right, Jeremy! This is awesome and even better with the little challenge from Craig we've got going on! Thanks, dude! 😎👍
I thought this was going to be a lot easier than the lunch box but i am not feeling to confident now seeing the struggles to get these going fast! My kit arrived today so I will be working on my build this weekend and also pondering what I can try and do to eek a little more speed out of it! Good luck on finding the right combo of gears and motor!
So did I, Addam! I've had 4 runs now and it's not getting any easier! Even at 29mph, this thing is a handful! As soon as I've found the fastest motor on this gearing, the fun really starts as I ramp up the gearing... Then it's how straight can I keep it! Enjoy the build my friend and tons of luck to you too! Thanks for the great comment and see you soon!
Uhh, yeah. I’ve been surprised a couple of times too when comparing specs to reality. But yeah, state of motor, quality, voltage of battery, winding out the gearing, bottle neck of both amps and ESC to the motor … and things happens 😅
Great point, Mikael! Quality is a big factor in the performance of these motors, unfortunately there is a lot of cheaply made stuff out there! Generally, you get what you pay for, except that Absima Thrust Eco 18 that was an absolute bargain! Cheers! 😉👌👍
Awesome mate 😁 well done 👍
Thank you very much, Mark! Cheers! 😎👌👍
Love it. Was expecting to break past the 29 though.
You and me both mate! Don't hold your breath though!!! Cheers!
I run that Trust eco 15 in my DT03 fighter buggy . Runs nicely for what I use it
Hi Dave 👋 yeah this thrust eco really is a great motor, it just didn't do any better than the 18t which surprised me! Definitely worth a buy at 10 quid though! All the best from Mark 👍 🙌
29 aint to be sniffed at 👍 i wanted to get involved with this speed run challange, but just aint got the time 😭 hopefully it will be back next year 🤞
Too right, Richard! Sorry you don't have the time, I know how it is, but if there isn't one next year we'll arrange our own! Cheers!
@@MarkBryanRC i’ll hold you to that 😁
Definitely mate! 👌👍
Wow... puzzling for sure..... One thing I found in this video different and it may be why the speed has dropped with the faster motors or I am just dreaming it could be the reason because I wanted to see more speed for you guy's! I did notice the first run you powered your car with a awanfi battery and if I recall those were pretty good nimh packs.... could this be maybe the other battery is not up to the task of powering such low turn motors? I may be dreaming but you never know!...Mark running out the door now calling Rob with car and fully charged Awanfi battery! LOL!!! Never know
Hi Steve and many thanks for the thoughts! Yep I agree with you, that's why I did try the other battery, we did film it but I thought the video was long enough and it only did the same speed. Those Turnigy batteries and the Awanfi are the best I've got so that's why I'm using them. Many thanks again for trying to help, it really is appreciated my friend!
Good to hear, strange the lower turn motors are not going faster? could it be the pinion gear is to big and it is not allowing them to get up to full rpm? maybe try a smaller one at least 3 to 4 teeth smaller maybe? I don't know what else it could be other than those are not the best of motors then? they don't make good brushed motors like they used to before brushless came out.. maybe try one of the associated 17T radon ones they have they used to be pretty good. @@MarkBryanRC
Thanks again, Steve! We think alike, for sure! I did try with a simple test - the foam tyres are a much smaller diameter than the rally tyres so fitting them is a really quick way of dropping the gearing. But guess what, Steve? Every motor was exactly 2mph SLOWER with the smaller wheels?!?!?! I think that means they can pull higher gearing... We will see for sure when I start increasing the pinion size - stay tuned dude!
O good idea with the smaller tires i did not catch that they were smaller. a couple teeth on the pinion should hopefully jump up a few MPH 32 or 33 mph would be nice! @@MarkBryanRC
@@ShenRC Sorry, I should have said in the video - my bad! Thanks Steve, yep I'm actually hoping for that speed increase! Cheers!
Very Nice vidéo 😊😊
Thank you, much appreciated! 😎👍
Fun stuff there! I'm catching up to everyone, though. Look out! I just posted my third speed run!
Thanks dude, fun is the name of the game for us here! You posted No 3? I'll check it out!
Wow great job though your running faster then I am with Brushless.
Thanks Kevin 👍but yeah I'm sure you will be catching up soon 😉
29 again mate . Over to craig 😊👍
I need a bigger road Dom!!
Thanks mate! Wait till you see the next run of mine! The challenge is definitely over to Craig now!👍
You sure do, brother! 😬👍
@@MarkBryanRC have u got another run coming mate ?
@@rc-dom-uk I've already recorded the run on the Orion 12T motor. Waiting to see what Craig does before uploading!
Back to the drawing board Mark. Think more in terms of just raw naked speed and power! Good luck anyway i'll be watching🍿
Definitely! This is harder than it seems! I have a few things to try yet though. Glad you'll be following along, much appreciated! Cheers! 😎👍
ARGHHHHH ... SO Close... LMAO Well if you cant get there you might as well have fun trying.. I am still scratching my head a little on the fact you went to a faster motor, but went slower????? Thanks for sharing. Good luck the rest of the way
I know mate!!!! I hammed it up for the camera but I was disappointed! We will get there soon I'm sure. I think quality has a lot to do with these motor's speeds. Thanks for the support and motivation, buddy!
Hey don't sulk Mark, you are still winning the brushed contest unless there is one that I've not seen that beat you? So the foam tyres are better after a little warm up? I was determined not to spend any cash on this but I might get some. Do you know what they are or should I ask Craig? My only plan to beat you is to put even higher gearing in and one of those 15t motors which I do have already. I'm going to have another go with the brushless set before I convert to brushed anyway. The trouble is finding a flat and empty road or car park. Anyway an entertaining video to kick off my weekend. Cheers for now mate 😁
I know mate, but I was bloody certain those 15T motors would top 30!!! I got 30 in the M03 with that Absima 15T. But yeah, I was hamming it up for the camera, it's a good laugh ain't it?!?!?! Craig ordered the foams for me so best to ask him. Good to know we will be competing and it all helps with the interest, I'm getting plenty of it here! It's gonna be close then because we have similar powerplants and gearing options - as we've already seen, a lot of it is down to being able to get the power to the road and to stay in a straight line!!! Cheers my friend, have a good weekend! 😁👌👍
Hi Mark, 29mph can be broken!! I have to watch the latest upload 👍🏾
Hi Paul, yeah it's gonna get smashed, pal! Hope to see you on the next one my friend! 😎👍
29 again mate could be worse mark great video 👍
Tell me about it, Coryn! Yeah, I was acting up for the camera a bit! Cheers mate! 😎👌👍
30!!! So close
I know!!! Next time... 😬🤞
try a surpass brushed motor they are so good for 15quid!!!
Thanks for the tip, Wayne! 😎👌👍
Nice! (**he said dejectedly**)
🤣 Oh yeah! Definitely dejected! This is harder than it seems, dude! 😎👌
29mph is pretty good for a brushed motor. I'm working on my brushed entry now.
Thank you Sir! But yeah, the best motor will get a gearing upgrade. Lot's of luck with your entry, pal! 😎🤞👍
Nice runs almost got that 30mph, that is the fun and frustrating part of speed runs you think you are going to go faster by changing a gear or motor and then you go slower.
Thanks, Kurt! WE got there now! But yeah, lots of frustrations trying to go faster but we are still having fun along the way! Cheers!
How did you mounted the 15T?
The TT02 Motor Mount just offers 16T , you justed used this?
The 15T is referring to the 15 Turn motor. The numbers on the motor mount are for the number of teeth on your pinion gear.
Great run dude, but wtf man, why isn't a 15 turn motor faster than an 18 turn? Is it workmanship, is it materials or maybe quality??? I do hope your luck will change and you break that elusive 30mph threshold!!!! Are you using your best NiMh pack? Remember, the voltmeter is your friend for checking your packs, playing with timing on the motors does to, to a point. I use Contact foams on my SR with brushless power, do you know what "Shore" those tires (foams) are? Higher numbers are more firm and lower numbers are softer, I think. I guess we'll see what happens in the next video. ATB my friend!!!!
Many thanks brother! I know, it's a conundrum for sure. Agreed, it must be down to manufacturing tolerances and quality. Yep the batteries I'm running are the ones I know give the most oomph! Tried others just in case but no joy...
No idea what the shore is on these, but after a short run they give excellent grip. Crap when cold though! ATB to you too my good friend!
So are you guys from Walsall or something? I'm down road in Sutton Coldfield and never see anybody out with rc apart from the odd rc planes in Sutton Park. So does lower turn equal more speed usually? I have a FTX Banzai but it only does 20mph on the stock motor. Worth me trying one of them 15T Absima motors before I have to go brushless?
Hi Dominic, no we are from Oldbury, you were not far off in your guess! We never see anyone else RCing either, seems we are somewhat spread out across the country, although there are a lot of us in the hobby.
Yep, lower turn motors are usually faster (higher revving) and yeah, I reckon your car will be a lot faster with the 15T Absima fitted! Have fun with it! 😎👍
@@MarkBryanRC Oh no I'll be trouble for getting that wrong, my Mrs is from Smethwick next door! Nice one for the advice, it has a 20 turn Ftx motor in now, good for about 20mph.
@@dominicchesterman2107 Haha! I'm actually from Smethwick and Rob lives there!!! Small world! Yep, you should be good for 25 with that 15T motor! Cheers!
It's so strange these motors not giving a good performance. I think pinion time 🙂
I totally agree, Mal! Got me scratching my head! 2 more motors left to test and then the fastest will be geared up. 30+ will be done! 😬👍
@@MarkBryanRC If not a big rubber band and flywheel 🙂
@@BasBoyRC Definitely!!! 🤣🤣👍👍
Pls keep the camera more steady next time! damn tamiya's won't go straight, perhaps some toe in or out will do the trick? I think when ur adjusting the steering to try n keep the car straight is hindering hitting that 30mph. Otherwise great video
Sorry about that, Rob is zooming in too much - I'll tell him but can't guarantee he'll listen! Got toe in already, maybe it's my bad driving?!?!?! You are right though, need to keep her straight! Cheers!
A sulky face always helps, if you ask me. 👍
It's one of my specialties, Steve!! Cheers mate! 😎👍
now i'm not that familiar with the motor's and such but could it not be torque related that the "faster" motor's are actually slower?
at least how I see it in my head is that higher torque would result in less RPM lost because of resistance so maybe that's why the 18T matched 1 of the 15T's and beat the other?
don't know the torque figures of the motors used but did notice that the tamiya torque tuned, GT's and the tamiya BZ's have a pretty big torque bump compared to most other motor's (most carson etc) where i can find the torque number it comes out to about 10-20 mnm (Millinewton Meter) the torque tuned and GT's claim 30mnm and the BZ's 49mnm.
at least seeing these results and what I've heard left and right, RPM / T is only part of the story and the other part they don't like to talk about unless it's high :P
or maybe due to manufacturing variation it's hard to make promisses..
You make a great point! I'm still trying to work it all out! From past experience (what little I have of it) that Core 15T went faster every time I RAISED the gearing, I was expecting it to get slower at some point but it didn't. But you could be right about the 18T having more torque and being able to pull that 22/64 gearing.
I agree about the Tamiya specs, very misleading. The specs I can find for the Absima and Core motors are very sketchy, too. The numbers are definitely only part of the story. I think trial and error is the only way forward, fingers crossed I get it right! Cheers! 😎👍
Too much wind resistance on those body posts mate 😂😂😂😂
Haha, I never thought of that Derek! 🤣Cheers mate, take care! 😎👍
@@MarkBryanRC 😁👍🏼
Mark take the wing off😉 that will get you the magic 30!!!!
Thanks James! Yeah I thought about that, but the car gets very light as we approach 30, I might even look at adding more downforce! I know it will go faster when I start gearing it up, and as you will see, stability becomes a determining factor at 35+ !!! Cheers, mate! 🙏😎👍
@@MarkBryanRC l see! I was thinking less drag = more speed as a easy tweak but messing around with gearing is usually more successful But sounds like you are already on the right track...that's more then Pete Wylie was doing the other day! Iol run Forrest run!! lol that guy is a hoot!
Take it easy buddy.
Well mate, I could be wrong, we will see! Yeah Pete was heading for the sky!! Made for great viewing though! Will do mate, take care too!
Great run Sir!!
But beware..... as you're probably fully aware this is no longer the TT02 Speed challenge..... its now the beat Mark Bryan challenge!!
Pete, Craig etc all coming for ya bud.... so that's enough of the defeatist attitude and long face!
Time to draw on your many years of experience and vast subject knowledge and go back to the drawing board and come back better and faster!!
I have full faith in you Mark..... Use the force fella!
Don't let the yoda down! 😉
👍 👍 👍 👍
Oh yes, Sir, I know I have a big target on my back! 🤣
It's gonna be close between me and Craig and now Pete, as none of us are going overboard with the electronics. There will be plenty of others out there with better setups so I'm happy to race-off against those two! I need all of the force I can get, mate! Send some good vibes my way, fella! Cheers! 😎👌👍
Mark what if you take the rear wing off ?
I thought about that Darren but I'm sure it's adding to the stability! Might do that though later down the line when desperation sets in! Cheers! 😁👍
@@MarkBryanRC yes it adds stability I have an Audi A4 shell and when it has no wing it goes well done the straight but not so good on the corners lol also if you could run a lower shell might help also? I was also thinking take out the front diff to see if that helps as it will be taking some power also for a speed run. 😁
Hi Darren, yeah I've had the same experience as you with wings! I might take out the prop and front diff later and see how it drives - Cheers! 😎👍
Oh No...
Hold on, that doesn't make sense!
A 15t motor SLOWER than a 18t motor? With the wires round the correct way? Would a bigger pinion do it justice?
And Thank You for the mention although I wasn't much help it would seem 😶😮
I have a Core RC 15T also Peter and couldn’t get it anywhere near my Superstock BZ speed. It is fast but not as fast as the modified ones it seems
@@theoagrc Aaah Yes, the modified ones have the adjustable timing plates on the ends, don't they?
Come on Core, sort it out for the Speed Demons, they need adjustable timing plates as well 🤔🧐
Hi Pete, yeah I know, you can see how dejected I was in the video (I did ham it up for the camera though!!!) I'm finding the fastest motor by using the same gearing and then I'll mess with gears.
You will get more mentions as we go along, my friend, you are so very welcome, I wouldn't be able to do this without your help, all those TT02 parts are coming in handy for this! Take care, mate! 🙏😎👍
We are learning a lot about brushed motors, eh, Craig!!!!
I only have that Orion 12T you sent that is adjustable, I need to play with the settings on that as you'll see! 😬👍
Still pretty good I think but I don't see why it's not going up on speed
I know Fonzie! It's all very confusing and gets more confusing very soon! All the best!
@@MarkBryanRC Lol 🤣 looking forward to it so far from the videos I have seen you are the fastest 👍😂
@@Fonzierc Well I was the fastest but someone just beat me! I'm not finished yet mate, lots more to come! Cheers! 😎😎👍👍
That's such a shame, I was really hoping that you'd hit 30+ mph mate! Oh well, better luck next time.............
I know, Barry, I did ham it up for the camera but I was disappointed! Thanks for the support and encouragement, it's just what I need buddy! 🙏😎👍
Nice. @c.k.hobbyshop just hit 36
Thanks! I just went and took a look - he's flying on that Fireball!!! Cheers! 😎👍
