1515 1.5d in an 8ight

[glassdoctor]

I've run a 1515 in my buggy and it seems to do just fine. Runtime and temps are very good. Mine is only 1700kv btw and I would race with a 46 spur and 14-16 pinions.

Gearing really depends on what you are doing... but I would guess 10-12t is where to be for racing. It should be fast with the 12 and just ballistic with the bigger gears, although it should not have any problem with pulling that gearing if the batts can handle it.
