these caps aren't like the others were u need another one on the receiver. even with the stock capacitor in b44.1, i don't need an extra with a savox servo, were others need to put a cap on the receiver along with one on the speedo.

btw 21 81 on a b44.1 8.5 is a speed demon, i am just as fast as full timing 7.5 and just behind a 6.5. Got 2nd in the a with my viper setup in 4wd.
