Gearing for FK'04

Anyone can help?

Currently I have using 124 with 33. Is that okay?

It really depends on the track. A good rule of thumb is to gear the motor so that it stops accelerating 3/4 of the way down the straight.

Your FDR with a 33 tooth pinion is 6.5 (124/33*1.77). 6.5 is pretty low for a low wind mod motor, but like I said it does depend on the track. Also keep in mind that another general rule of thumb is to go down a tooth on your pinion for each wind you drop. For example, if you are running a 33 tooth pinion on a 10 turn motor, go to a 32 tooth pinion on a 9 turn.

Thanks Josh , what is the FDR in average?

By the way, any more advice?

Can anyone share with us, what is the ratio (eg. 124/33) you are using for your FK'04?

Hi there!

I've been looking for a T1 FK04 Gear ratio chart but haven't found. :oops:

So I wonder if anyone could find one for me?
