Tamiya TT02 Upgrades - 29t Pinion

Installing a 29t pinion with a 64t spur gear gave us our best results yet! But there's disappointment for the Super Stock RZ motor.

This is great. I continue to watch with interest!

[@rctamiyaaddict4687]

Awesome, thank you!

I concur with the thought that you may have hit the limit of current that ESC can pass through it. A 80 amp esc may be in order. I'm still a fan of the low turn Radeon motors. Great video, and I'm certainly impressed that a speed run car is still keeping its great looks. I think mine was wrecked at just over 30 mph. Keep it up! Will you be entering this years poorboys speed run? Its coming up in less than 3 weeks.

It's great that you hit 30mph! I'm looking forward to seeing what you do next.

[@rctamiyaaddict4687]

Thanks. Hopefully we can squeeze some more speed out of it.

In Japan next week, I'm getting a 61T TT02 hop up gear an 25, 27, 29, 31, 33 and 35 motor gear. I will also pick up some cheap hop ups, motors and tamiya program servo has 5 settings.

[@rctamiyaaddict4687]

Very nice. Hope it all goes well for you.

@rctamiyaaddict4687 thanks, don't worry its not my first time there. The rc cars amd parts are way cheaper and duty free so now it summer I will travel liht and come home heavy 😅

I ended up with "Tamiya 54229 06 Mod. FF03 Pinion Gear 29T" and "Tamiya 54500 High Speed Gear Set" wtih a 64T spur . Motor is Torque Tuned and a 2S LIPO. Runs really fast...I have no way to meassure the speed.

[@rctamiyaaddict4687]

Have a 63T spur to try out soon

[@markconnor269]

Nice video 👌 shame about that motor 🤔

[@rctamiyaaddict4687]

Thank you. I’ll have to see if there’s anyway to recover it

[@SRG-HITMAN-11]

You need to polish the shaft as slipted pinion would of burred up the shaft power motor and polish shaft with emery cloth or fine file

[@rctamiyaaddict4687]

I think you’re right. Hopeful and get it usable again.

Awesome you got to 30mph, Bummer about the RZ motor... What esc are you using? I think most brushed Tamiya esc are rated for 23 turn motors. If your using the Hobbywing 1060 esc, your good to go down to like a 13 turn motor.. This is where gear ratios will come into play, A motor will only pull to a certain ratio then fall off or over heat, hence, why some ratios are faster with a smaller pinion, its weird....

[@Paul__FC]

Hope to see you this year in the PB speed run. Of course driving an," Eddie Van Something " when it's announced.

[@rctamiyaaddict4687]

It has the ESC it came with, THW-1060. Be looking forward to see what car PB RC goes with this year.

[@UncleBobsRC]

@@rctamiyaaddict4687 Awesome, the 1060 seems to be the top choice.

@@Paul__FC Me Paul? Not sure what I'm doing....

[@Paul__FC]

@@UncleBobsRC yes! I miss that caddy to this day!

[@aviano72]

Hmm that shaft on your motor does not want to cooperate 🙃 Did you find out what was wrong ?

[@rctamiyaaddict4687]

The grub screw was out. Probably the pinion damaged the shaft while it was spinning around.

[@dans2423]

Great video. But why did you use a bigger spur gear than the stock one?

[@rctamiyaaddict4687]

The stock is 70t, the one installed is 64t giving a better ratio
