Re: Switch Between Two Receivers on the fly

<r>The ESC needs to be calibrated for the exact endpoints and mid-point of the throttle signal from the receiver, so you might run into trouble trying to do this. If the throttle signals are close enough between the two, then it could work. However, you'll probably find that you'll always have to po...

<r>You can't directly use the 12V battery to power the receiver (because it probably has an operating range of around 4.5-6.5V).

Re: Proportional Throttle/Braking/Reverse with RC speed cont

Doubling the gearing for (theoretically) double the speed would also double the load on the motors, which would increase amp draw (exactly double? I don't know for sure). I predict doing so would lead to a much shortened life of either the motors or the ESC.
