First of all sorry for double posting, I also asked this question in the JRX-S forum, but nobody's on right now, so here we go:
OK I got a little problem.
About two weeks ago, I installed a spektrum in my Helios. Then I installed a Personal Transponder.
->This is what's going on: when the batteries start to dump, the servo movement slows down and when I pull on the throttle, the transponder's LED dimms down and out. When I release the throttle, the LED lights up again.
I suppose the servo needs more current or something, or the GTX can't supply enough for the SPEKTRUM, PT, and 94360Z servo

do you think I need a capacitor anywhere? (only capacitor on the car is the big one that came with the GTX)
So, in the beginning, the car drives LIKE A DREAM, then I have this problem, before the end of the race.
I don't have shitty batteries and tried three of my packs. Same problem.
Thanks in advance!
You can see my setup below.
