RE: relatively new to rc, don't know what to do
Throttle problems? No, it is the fact that you need to reverse the throttle on the Futaba transmitter. Futaba is just the opposite of most other brands on which way the throttle need to be for most ESC's. Just flip the reversing switch on channel 3 on your Futaba transmitter to REV. It is most probably on NOR when you get full throttle at low stick.
