What mode do you use for 4 cell stock racing???

try 5 Al it seems to be the best . See you at the track

what is up with the blue wire, can you just cut it off?

i cut my blue wire almost all the way off.it is for a cap if you want to run one.i choose not to so i got rid of mine.

actually it is for a FET servo that hardly anyone runs, and yes you can cut it off without any problems!!!
