Guys if you look on Horizon's site, the mustang's Rx is 3 cell compatible, has 2 modes for controls. and yes jumpers for v-tail etc. The stang is running a 480 motor, more than likely the same one as the Stryker. Not real sure how long the stock motor will hold up on a 3 cell, from what I remember was only around 15 runs before it puked.

Watson,
You need to check the amp drawl on the 480bb, per PZ the stock speed control is rated for 15 amps. I doubt the stang's is any higher as its running a gear box.

Critter,
the servo/ rx deal was way back when. I think Pz figured why give it a way if they could make you buy it.
Also on your Rx problem, check the 2 motor wires where they connect to the rx. If insulation is cut too high they can touch one of the components right next to them and fry.
Sorry but it's been quite a while since I looked at a PZ rx.
