The gear ratio comes in to play.
Not only that ,trasmission plays a role ,if you calculate wheel rpm X Crown Z / pinion Z you will always get less than motor RPM,which is ( wheel rpm / motor rpm) the rate of transmission efficiency.By testing several SCX 4WD cars i have found the front
trasmission to have a lower rate than the rear,my theory is that the long front driveshaft is never 100% straight,causing vibration ,therefore consuming energy.

I just had a chat with Chris,club stages (all five of them ) will be run during the week (in one afternoon) starting Monday Sep 8.Stage in Chaitas Racing Garden will be run most possibly on Sunday 31 provided Daves car has arrived.

In the meantime i will tackle mine and miveson's cars in a try to fix them.

Hi Craig

Broken chassis needed replacing. Also as gears had been chewed due to twisted chassis issue, had to replace axles/gears and swap wheels with the control tyres from old axles to new ones.

Sums up my year, a car with a broken chassis still finishes in 5th place well ahead of my poor excuse of a race car lol

Doesn't chassis replacement equate to a new car build, even if it uses the same parts?

Hi guys

If my car can't be used because of the new chassis, then so be it! :wacko: After it had broken, it wasn't possible to run it anyway.

Cheers
Dave

Hmmm, there's an interesting situation...

Can we shoot Bargwanna an email?...... :-)

Doesn't bother me that its been fixed, every car is different, it could go either way really... Up or down the ladder...
