Default FDR and Rollout to figure out gearing

Can you figure out correct gearing by comparing FDR and rollout on another car that is geared correctly even when the motors being used are different? Is there a rule of thumb?

Not really, because the motors are different. You can use somebody elses gearing as a starting point, go down a couple of teeth to be safe.

Or just use gearchart.com to calculate the FDR or rollout on different cars.

Like the post says here above, you can use somebody's FDR as an indication to start with...
