TTO2R DRIFT CONVERSION

[jayarr55]

Hello all,
I've converted my tt02r to a rwd drift set up.. I bought the yeah racing drift kit.. I've also got a yokomo v4 gyro.. ever since I installed the gyro I've got steering wobble that I cannot get rid of.. I've tried moving the gyro from the front to the back and now to the center of the car can't shake wobble.. I've changed servos twice.. I am running out of ideas..

Are we sure it's not the electronics its self and it's just the poor build quality of the steering rack? Could be a possibility. Had a tt02 myself and many others here as well and we all experienced the same steering slop issue.

If it's not the actual car, could also be that the gyro is set too sensitive?

The gyro has been adjusted many times by myself and a couple other buddies with drift cars from my local hobby shop. They end up scratching their heads.. the yeah racing kit is OK looks nice but not sure of the quality of steering racks looks sturdy and loose..

The electronics are all new.. unless I've got a faulty gyro

Yea that's normal for Yeah Racing. Even stock plastic parts too. I would be scratching my head too if I haven't built up a tt02 in the past. Got excited building it but first drive I was disappointed in build quality and performance. And most of the time the upgrades out there is just to add bling and really don't have any affect on performance.

I mean it could be but I highly doubt it though. Yokomo is top tier stuff

The TT-02 front suspension is so loose and wobbly, the gyro is likely seeing that and trying to correct for it. Stick the gyro as is into another chassis and I bet your problem goes away.

 

[jayarr55]

Yeah, it was an expensive kit too.. lesson learned though, more expensive doesn't always mean more performance...Any other brands I should use besides the yeah racing steering rack?

 

[WickedFog]

Oh, I have the Yeah Racing drift kit on ours too. The car still won't drive a straight line.

Aha.. dang.. I've definitely been told that before..

That YR steering rack is almost worse than the stock plastic stuff. The bearing bores are oversized, adding slop to the steering.

Tamiya makes the only steering rack any good for it, but it is stupid expensive. And it still won't solve your problems. Grab the front wheels and wiggle them front to back while watching the kingpin atop the spindle. Just check out that slop. Keep going and look at the slop at the hinge pins in the chassis. More slop. There is nothing you can buy for that chassis that is going to solve your issue

My advice - put a body on it and stick it on a shelf. I have over $600 wrapped up in one and it is still a pile of garbage to drive.

Lol that is exactly how it is now shelved with a nice shell.. sucks tho.. might just go back to 4wd.. it performed better that way

When I had mine I kept it 4wd and still preformed like a tamiya. Sloppy steering, diff stripping under brushed power bc they're plastic, ect. Still won't fix it imo but atleast its semi more drive-able, maybe?

I had a 4600 kv castle motor on 3s on my tt02r and it held the power fine.. will admit it would not go in a straight line though .. it would eventually spin out ..

well it could be because it is a shaft drive TC and torque steer being a thing but its just normal tamiya quality and issues so I ain't surprised of it trying to spin out and trying to drive straight. I sold mine which was a basic TT02 (was running stock tamiya sport tuned brushed on 2s) and I was constantly trying to fight the wheel/car trying to get it to drive straight which was making it super hard to have fun with the thing. And this was just purely just hooning and bashing in my alley. Had the thought about racing it but I was like no. Not putting that time and money into a poor car like this.

What servo are you running? I had the same issue running a AGFRC servo with my Yokomo V4 Gyro. Swapped out the AGFRC servo for a yokomo sp-03 and it’s unbelievably smooth now. My chassis is a MST RMX 2.5 but obviously electrics are pretty much the same across the board
