Default Turn vs. FDR chart

Is there a chart for what gearing you'd need per what turn motor? I'm guessing it wouldn't be exact but ballpark figures could help us newbies out.

Not really. There are a lot more factors involved in FDR than just the number of turns in the motor. Primarily the type of driving you are doing. If you are racing then the FDR depends on the size of the track, how long the straights are, how many track turns there are, and if it is on-road or off-road. If you are just driving around in the street how long you stay on full pegged throttle is going to affect the FDR to keep the motor running cool enough not to burn up.

Wow I didn't even think about track size which should have been my first thought.

Its probably easiest just to ask people who are running in your class what ratio's they're running and use that as a starting point. Different motors also have different characteristics and therefore are geared differently to get optimal performance.

Most motors have a guide in the box.

Well, I know my trinity and LRP ones do. And Novak have a table on their website.

In the manual of my Corrally 5T motor there is a chart listed of turns to ratio, but in real it is more an indication.

That's probably a good guide for a starting point. Other motor manufacturers suggest gearing ratios for their motors too.
