I just ran my 3pk Spektrum today. Indoor carpet with foams. Futaba 9550 servo. KO VFS1 Pro ESC. Stock class. EvoIV. Worked pretty good. Normally I ran the 3pk in HRS mode. The Spektrum didn't feel any slower at all.
It felt really weird though driving without a normal antenna. I kept reaching to raise up my antenna.
Only problem I did have today, and I wasn't too sure what it was.. but I got flipped over in the last turn and the car rolled around and landed back on the wheels, but the car was dead. No steering, no nothing. Transponder light was on. Spektrum light was off. ESC light was on. But nothing. Turn off the car.. then back on.. it was fine. This happened twice. Once during the Qualifier and once during the Main. Same turn. Same type of roll. Same problem. No idea what happened. Maybe my ESC setup buttom was pressed in (doubt it since I try it now and still works fine)? Maybe Spektrum? No clue.... I'll just do some research... Maybe it was failsafe??
Other than that I like it alot. More race testing next weekend....
