Batt. and ESC gettin hot. and getting shorter run time. never did this b4, why?
i have the 2100 prolite and jgf 450f 11th pinion. i crashed this heli about 3 times and i recently fixed it and began to notice hot batt and esc. i thought it was the weather in the beginning but even in the shade it gets hot as hell. i flew this heli about 80 or so times and never had this problem. also im only getting 8 min of flying time and the motor loses power at that precise time. b4 i used to get around 12-14 min. i tried other batt and does the same thing. should i reprogramm my esc?

my trex specs
325 woodies,
450f
align 35
401gyro/ hs56
3hs56
align 2100 11.1
TP 2100 11.1

thanks
is that a new heli? Oh no honey, its the same one w/different stickers.....

Sorry mate. You've killed your battery. 8 mins flight times are normal. 12-14 min and most likely you've run your packs down too far.

Do the maths. 80% of 2.1Ah is 1.68Ah. Fly for 14 mins this means average current consumption is 1.68 x 60/14 = 7.2A

Check the specs of the motor and tell me this is correct.

11t on a 450f. What is your throttle curve cuz that could be some crazy headspeed. On a 9t that motor runs 2800rpm at 100% throttle. How many mah are you putting back into the packs? 12-14 mins is unheard of on 3s 2100 mah.Timing is everything
