Hey Jerry, yes i've seen your crazy stretched lightning
Cant wait to see it running, are you still going to put a Bolido in it
I'm running 2 5s 5000mah Neuenergy packs in parallel. The V1's mind you, just a slower charge rate i think. As for temps, it was really hot out, around 95 F, so i cut the run short a little bit. They were;
motor: 130-150F
batts: 110-120F
ESC: 120-140F (fan came on a couple of times, but after 30 seconds went off)
The drivetrain is holding up really well, make sure you run hardened steel pinions and spurs on your speed machine, no melting here. Really happy with the UE gear, certainly doing its job. The RC alloys dogbones are really beefy as well, you'll definately be pleased with them!
