fragile spur gears???

yes that's what i thought!!! lol! :)
Prhaps a 4s or 5s lipo would be nice... but probably too much y motor...
I have more and more fun with the 9L since Squee gave me the good ratios to use... that's amazing how the motor behaviour is different with my new ratio (16/66)... old one was 16/72, the motor didn't "took its turns"...
I will have a look at Maxamps products... 4s lipo should be a solution...

>>>Please, can someone confirm that 5s lipo are too much for a Feigao C 9L + bk9920 ???
