Right now i am running a 7.1925FDR. Speed passion 17.5 and stock club esc. I just don't want to burn anything up. Will I be OK???
If you're talkng about 48 pitch and 2.055 internal ratio, I'd go way up on the pinion at least 32 tooth! Around 4.5 FDR would be a good starting point. Then gear to your speed/driving comfort level and temp.

Holy snap!!! Did not even think they made a 32 tooth pinion. I will give it a try and report back. I was thinking I had to go the other way, like a 10:1 FDR. I had it wrong.

Duckstang, if you're using the Tamiya 70T Spur, then it is NOT 48p like most people will lead you to believe. Stock Tamiya uses the AV pinion set which has bigger teeth than 48p. 0.6metric pitch is closer to 48p but even then it will run choppy. I have 26T pinion for all three pitches and the Tamiya AV pinion is roughly 1mm in diameter larger than the 0.6mod or the 48p. the 0.6mod is <.5mm larger than the 48p. Might not seem like much but trust me, its enough to chew up your spur.

Only reason I have a 48p pinion is because of my blitz. Went through 3 spurs in as many months using tamiya pinions before finally getting a 48p.. 8 months of constant bashing and the spur shows no signs of wear now, even with it being wobbly(common blitz design flaw).


If you want your spur to last more than a few months of running, then stick with tamiya AV pinions or upgrade to 48p spur and pinion to get more gearing options. Or better yet 64p and run ultra smoother and even more gearing options.

Thanks for the info, liquidgenesis. Will Associated tc3/4 spurs work in the tamiya's?? My LHS carries a whole lot of associated stuff.

Yes, & any standard Kimborough spurs will fit perfectly(those are what I've been using for years, they've never let me down)....

Wait.. So is it bad to be using a 48p pinion??

I have a 28t pinion with the tamiya stock 70t spur for a 13.5 motor..

Is your 28t pinion Tamiya? What he is saying is Tamiya gears are not the same as gear from other manufacturers. They are slightly of different size and will not mesh properly. If you are using a Tamiya spur and pinion then you are fine.

I think it's a Robinson pinion.
If it is bad to use this pinion, what damages could this cause?

Does anybody have any advice on freeing up the drivetrain? I have worked on the bearings and everything spins free until I attach the belts. I have them at the stock setting. I tried loosening them one notch but the drag is still the same. I'm trying to free up the drivetrain as much as possible. Thanks

hi all,

i just got my TA05 ver.II R this afternoon.

I would like to check if the TA05 ver.II hop-up (namely aluminum part such as racing steering (tamiya part #53848), etc..) are perfectly usable on the "R" version??

Thank you
