hey guys, just finished building my US '007 car & I want to know how you all determine what pinion to run based on your tire size. I am a bit concerned on properly selecting the right pinion for 19 turn based on 57mm tires..I'm running it tomorrow


can anyone help????

Chekpoints like to roll out in the 33-35 range. You might have to switch to a smaller spur (108) to achieve this type of roll out.

teamgp

With a 116t (64p) spur, start with a 35t pinion. You'll probably end up with either a 36t or even 37t pinion though. Just trying to make sure you don't fry the motor.

With a 112t spur, start with a 34t pinion and you might end up with a 35t or 36t.

For 57mm foam tires, the target rollout should be between 32mm and 34mm.

what temp should the motor be after a 5min run?

I have the same question, but am using a CO27 with 57mm tires.

thanks for the info A.Rhoades & TeamGP, but what do you all mean by "rollout"??? is this the amount traveled "per 1 revolution of the motor"????

I have never ran "foams" before and I don't want to over think the whole methology about it....I just can't afford to "fry" a motor (know what I mean??? X-Mas killed by checkbook this year)

anybody have a rollout chart for foams????

thanks for the info!!!

For a Co27 on a med size carpet track you will want to be around 31-33 pinion w/116 spur.

Yes, amount of distance car travels per one revolution of the motor.

Rollout = Tire Diameter X 3.14 / FDR (Final Drive Ratio)

This is a great site for reference - www.gearchart.com

awesome!! Thanks again..

last thing: can you give me a good starting point (rollout) for stock & mod foam as well (based on 57mm tires)

thanks A. Rhoades

Save some time and math...... www.gearchart.com Print the charts for foam and rubber any config u need.

And dont forget the 007 comes with roll out charts in there setup book

I ran into a little challenge with the stock 116t spur, I believe a 35t pinion was as large as I could go.. So, I'd recommend a 112t spur for the smaller tire sizes..
