Rebuilding my old .15 tmaxx now. Haven't ran it in 15 years. Bought it back in 1999. You shoulda seen the look on the peoples faces when I brought it to the same hobby store I bought it at 22 years ago. Total blast from the past.
Great job! Just bought a used T-maxx and am in the process of rebuilding... I'm a pure amateur at this stuff these videos are THE best I have found on the interwebs - you are extremely thorough which helps a ton! thanks!
Hey thanks for the breakdown. Thought I was going to have to take it to my local hobby shop. They can’t touch it for two months. Seeing this I’ll gladly tackle getting my old t max x back up and running.
I got my block for 18$ hoping it'll run as intended shattered my connection rod and tore up the sleeve aswell as bent the crankshaft i thank you you helped me a great deal
I have a truck for many years. I honestly don't think it has 10 hours of play time on it. I had children and I put it away. He it is 16 or so years later well I think I would change over to all electric. I think that the electric car etc have come a long way. Thanks for sharing this video with us.
Electric tech has most definitely come a very long way in 16 years. From NiCd to NiMh to now having high capacity LiPo batteries, and from brushed to brushless motors, it is a whole new world out there.
Great job again Tony. It lives again.... soon. The truck look likes it's chomping at the bit to get outside at the end lol. Is that a trim adjust you need to do?
Love your motor rebuild. I was just given a t-maxx 2.5 r without a remote control from my brother-n-law. I plan to rebuild the motor using this video. Do you have any ideas about how to obtain a new remote control. Thanks
I'm glad you like the series. Be sure to check out the new series where I go completely through a 2.5 from top to bottom in a lot more detail than in this series. th-cam.com/play/PLabJwbJaz4QuWqKXO5IQByu8D6_rn2c9F.html
Thank you for the help but I got ride of that truck I went a bought a revo I had to buy a 3 channel receiver but the car has two steering servos and a throttle servo do I need to buy a bigger receiver for both the steering servos work at the same time
Thanks for these well documented videos on the T-Maxx! What year is ir? Any good resources on it or a link to the original manual online somewhere? I got a box of old truck gear given to me from a friend including this exact t-maxx but he didn't have much info on it. He was trying to convert it to brushless after he bought it but then gave up, now I'm looking to rebuild it since the original parts are in great shape, just totally disassembled.
I don't have the manual and I can only find diagrams online. If you can, come over to www.Rc-Help.com and post a thread and I will try and help you out in any way I can. Rebuilding these is fun, but can also be stressful. Be sure to post some pictures of what you have now so we can get an idea of where you are in the build. Hope to see you there soon.
Emery cloth is a little excessive on the crank! Use a scotch bright pad at the most. Now your engine will leak oil even worse then before. Even with a new bearing. Might take a bit but it will leak!
I just switched my EZ start for a pullstart. For some reason the battery would die within seconds and it would only crank the engine over slowly. I might buy a new motor one day and see if that solves the problem.
Thanks for taking the time to reply, it's much appreciated. I did buy a new battery for the wand and also replaced the wiring loom, but it didn't seem to make much difference, although I don't have a way to verify that the charger I'm using is actually charging the battery, so went the pullstart route as it was cheaper than going through the elimination process. Eventually I will buy a decent battery charger, switch out the motor and as a last resort I'll replace the wand. Cool site, I'll keep an eye out for that article regarding the T-Maxx starter.
hey man, what way is the flywheel supposed to turn? im hooking up a pull start on my truck i dunno if i have my one way bearing unside down or backwards or whatever. thanks .
Yeah, I got a newer one too, exept the guy never tuned it, soo it ran way too rich, and didnt know how to drive, but the 3.3 runs great and I'm happy, it was a steal for 50 bucks i must say!
I need some help I have a tmaxx 2.5 and I think my electrical is screwed up because when I hit the throttle it steers and I know I have all the wires hocked up right but I am missing the shifter servo would that have anything to do with it
Left you a comment on a new 2.5 is seized ! I can work it back & forth but it will catch TDC. Should I pull it apart before a break in or is that normal ? Don't want to strip out easy start gear's .
If an engine sits around for a long time, it will seem to lock up. It's just the oil getting very thick. Use some WD40 down the carb and down the glow plug hole and work the engine for a while. You can use the electric start to do this if you want as long as you can spin the engine over by hand. The WD will help to loosen the oil up. And also, Traxxas says to use WD after running it as well. Better than after run oil, and will not cause a lock up issue. Hope this helps.
I prefer to soak and clean the parts in ether. It lifts oil and dries immediately. I find WD-40, even the WD-40 white grease attracts a lot of dust. Awesome video though. I learned a lot. Thanks.
the brass piece inside if the needle snapped, and i bought a new tmaxx 2.5 on ebay, it is very nice, only ran a half gallon of fuel through it but i was going to put the batteries in the battery box, and the pack where you clip the batteries in, and the pack is gone, i was hoping you could make a video of how to change the packs between trucks, i was going to take the one off my other truck but i dont know how, if you could make a tutorial, that would be great thanks again, bigmom lol (im a guy)
Also another cleaner u can use that works very well.. if u have any old or contaminated nitro/glow fuel it'll work fine and removes paint too (higher nitro contents work better than lower ones.. old 20% nitro is fine, 30 is even better!)... but for after run maintenance DO NOT use WD-40 (it may work ok for short term but long term it's terrible.. WD-40 has kerosene in it and will evaporate too.. ALWAYS use after run oil and I hear also a 50/50 mixture of Automatic Trans Fluid and Marvel Mystery Oil works as an after run oil which I never tried but heard Adam Drake does with good success.. personally I use actual after run oil.. shame Prather after run oil isn't made anymore, wonderful stuff!)
Yep, I always try to use actual after run oil when I can. Back when I made this video, these engines never sat long enough to have any harm from WD-40, but yes, for anything over about a week, definitely use the real thing. Thanks for the comment Aaron! www.Rc-Help.com
I have the tmaxx 3.3 that is getting a rb tm523 ive had issues with rear diffs stripping would a locked axle solve the issue or will it cause other issues
hey, i fixed to the new truck, me and my buddy who knows more than me at this, worked on it, and we got it working. i stripped the wires down on the headlight power wire, and the receiver wire, we didnt know which was which, and he gave me a pack from another buggy so we power tested, and found it. anyways, its fixed and im going to use the old truck for parts, it turns out it was a .15, not a 2.5, mistake! but i havnt ran it yet, and it was my birthday yesterday so im eatin my cheesecake, Thnx!
NICE!!! Is it still running, or does it need a rebuild like this one did? Be sure to check out my new series on the T-Maxx 2.5. th-cam.com/play/PLabJwbJaz4QuWqKXO5IQByu8D6_rn2c9F.html
that was an aftermarket Con Rod. That is not an original TRX rod. I know there are two companies that make a beefier rod. Nice work. Are you still RCing?
I am still playing around in RC, but not as actively here lately. Hoping to get back into it either this winter or spring when things settle down a bit around here. I do miss it though lol.
the old truck was a .15, i ran out of space, i think the text restricter is kind of stupid, but thanks for listening to my pointless "story" i guess you could call it, these things are so cool! ill be back though, im sure something will break, i registered on the site, i will check it out every now and then, THANKS!
When ever i start mine it takes off by it self and the throttle is closed and when i turn the top end screw tighter it revs up higher. How do i adjust my carb so it stop taking off by itself?
The OWB is a one way 'clutch' that allows you to use a separate motor to start the engine but once the engine starts, allows the engine to free spin without grabbing it. www.Rc-Help.com
I need a little help. I have a traxxas Nitro 4 tec from a freind of my. I clean the hall car bout I want to know if the motor is good everything looks good bout I will have to get the electric starting that you use to start the car and the Nitro I don't know what cain of Nitro ore gas . I don't really know nothing bout RC cars iam starting to get on to. So please help me out.
It's my pleasure. If you want some more in depth videos on rebuilding this truck, check out my new series on a 2.5 T-Maxx - th-cam.com/video/hmbG_RkHLbY/w-d-xo.html
Because it is fun and it helps people that still have this engine. I agree, it is under powered for the size of the truck, but thousands of these trucks were made and people are still rebuilding them. Thanks for the comment. www.Rc-Help.com
This was actually at stock carb settings. But it ended up being the glow plug after playing with it for a while. It would run with the glow igniter on the plug, but once removed, it would die. www.Rc-Help.com

Can you link the race formula 12:29
was it cold when you started this? it didn't look like the clutch liked the temperature by how the truck was jumping

Why would you even bother to rebuild a pro 15 engine it has too little power for a tmaxx truck
Because it is fun and it helps people that still have this engine. I agree, it is under powered for the size of the truck, but thousands of these trucks were made and people are still rebuilding them. Thanks for the comment. www.Rc-Help.com
RcHelpDotCom also it has the shorter chassis right and shorter wheel base difficult to get parts for because you have to go through traxxas
You are correct, it is the shortest of the T-Maxx trucks if I recall correctly. www.Rc-Help.com

too lean but u sorted it
This was actually at stock carb settings. But it ended up being the glow plug after playing with it for a while. It would run with the glow igniter on the plug, but once removed, it would die. www.Rc-Help.com
