flm rusty heat issues w/ pics

[zeropointbug]

What are you worried about? 140F is a decent temp, it is normal for those motors... although, you could gear it way down and connect that extra pack, it may or may not run cooler, and you would tons more power. When you run 2s2p, you should take off the extra dead weight of the second pack... not good for anything, less performance, lower runtime, more heat, just a waste. Try that.
