I am having a problem with my power fading off and can't clear jumps after about a min or less in my desc410. I am running a vtx10r be with vst 550 4.5 with revtech 5500 mah 65c lipos. I have tried a few different esc settings so I don't think that's the problem. I have my punch at 100% throttle freq 12000. I tried different gearing and motor timing. My temps are fine after a 8 min main my esc will be about 160 and my motor 170. I have no motor temp cut off and my esc is at 240. I am not hitting lipo cut off I am at 7.5v after a 5 min race.

I am thinking its my motor or my batteries. I have 2 sets of batteries its the same with eather set. It was so frustrating this Sat at a local club race I was having problems clearing a triple that I should be able to over jump. I was in third in the main and just could not catch the top 2 with me packing that triple most of the time. But I did beat 2 teknos driven by some pretty fast local guys

Any ideas??
