A better question should be…what kind of amp are you drawing and how hot does the motor and battery get while pulling the wait for 5 mins?

the point was to get a idea of how much lift i had ,,not to drag 3lb around ,,the motor only pulls 24 amp at full and is made for up to 30 amp

You can wreck lipo batteries if you drew more current than their current rating. They are probably only rated for 12 A.

WOW, 1400 grams eh? thats prolly close to double it's own weight... add a second lipo on parrallel so you dont have to worry too much about hurting the one lipo with that amp draw and you could put a nice little camera under that thing... I'm gonna try that,,, just hope I can get one soon, waiting on a little more $$$ still, getting close, lol. Good experiment though, just keep an eye on that engine temp and how much power is going through the lipo's... Did you try measuring amperage between lipo pack and ESC at full throttle? that would be an interesting number to know....

Mark

PS - find out how many C the battery can handle continuous and burst, then multiply by MAH, so for EX, 8C continuous 13C burst on a 2100MAH pack would be 16.2 amps continuous and 26.3 burst
