Going from "reverse to full throttle" only once will destroy the gears. Joy. One more thing to like about Kyosho re res. 1 Share this post Link to post Share on other sites

While I'm a life long fan of Tamiya, Kyosho just did their re-releases right. Metal diff gears, slipper clutch's, all made for today's motors, and batteries. Comes at a higher price, but well worth it over all plastic kits, with 1980's technology. 1 Share this post Link to post Share on other sites
Killajb 1546 Posted May 9, 2022 For what it's worth.. I used anti-wear grease on my NovaFox differential gears and haven't had any issues. I run a 14T brushless that pulls the front wheels off the ground when accelerating. 5 Share this post Link to post Share on other sites

I took gearbox apart and checked gears,no sign of any damage to them.I put anti wear grease on differential gears as you said but still makes clicking sound when accelerating.Dont think there is much else i can do.

Killajb 1546 Posted May 28, 2022 I'm afraid anti-wear grease probably wouldn't solve a pre-existing issue with the gears, it was more of a preventive suggestion. Share this post Link to post Share on other sites

Seems weird that there would be clicking every time you accelerate, but no sign of any damage on any of the gears from that clicking. If it were jumping teeth somewhere, I'd have expected that to have left a mark of some sort. Share this post Link to post Share on other sites
tamiya3speed 463 Posted May 30, 2022 Do you recall if the brass pipe is installed in the diff gears? Or the pin on the long diff joint? Could lead to the diff jumping and crunching under load. Also make sure you are attached to the correct motor holes based on pinion choice. Share this post Link to post Share on other sites

Yes the brass pipe is installed in diff gears and motor holes are right for 15t pinion.I have been careful to make sure everthing was done right. Share this post Link to post Share on other sites
drc35 3 Posted June 17, 2022 My Fox always clicked and popped especially with Modified Motors,trimming and shimming did help somewhat. I think it is the spyder gears that are jumping? 2 Share this post Link to post Share on other sites

I took the gearbox apart and put anti wear grease on the diff and it helped a bit but still clicks a bit when accelerating.I have bought new gears for it just in case it gets worse.Does yours still click?

danimaldaisy 70 Posted February 6, 2023 I had a nightmare issue with a grasshopper re release. Turned out one of the gears inside the transmission was out of round from the factory. Tamiya USA sent our replacement gears and the issue is gone. Maybe take the transmission apart and rotate the assembly and watch for anything weird. Also a last issue when putting the transmission back together was a stubborn bearing that was never inserted all the way even though it looked like it was. DT02 and 03 transmissions had zero issues building Share this post Link to post Share on other sites
NClosidrvr 0 Posted February 9, 2023 I had this issue when I restored a vintage car using rere parts with a NOS gear set. It didn’t help me that I was reusing the old hex drive shafts too. Anyway the way I “solved” it was to carefuly add shims to keep the diff gears together. Took a few times taking it apart, reassembling, putting it on the ground to find it still wasn’t right, but eventually I got it. It’s also why I gave up on the car. I had the similar struggle with a Wild One FAV I built from parts. I Decided I was done with resto runners. If its not a new build rere, I’m not having it to run.

RichieRich 685 Posted February 12, 2023 If you have a cracked tooth, which can be hard to find, it will make a load of noise. I would check each tooth starting with the spur gear. If you need any help, I'll be upstairs sleeping. Share this post Link to post Share on other sites
