danny boy Posted March 12, 2014 Share Posted March 12, 2014 (edited) Hello. Can someone check if I have this right? My leopard 4082 motor pulls about 3500 watts at 140a. A watts to hp conversion is 0.00134102209 hp for every watt. So this means that at 140a the motor would be giving out 4.693577315 hp? Or have I got this completely wrong? Thanks for reading.

Bonez Posted March 12, 2014 Share Posted March 12, 2014 that is correct Quote Link to comment Share on other sites More sharing options...
Tug Posted March 12, 2014 Share Posted March 12, 2014 Yeah, one hp is approximately 750 watts. 3500 Quote Link to comment Share on other sites More sharing options...
ajlovering Posted March 12, 2014 Share Posted March 12, 2014 3500 / 140 = 25 volts Are you using 6S? If so the voltage will drop considerably at 140 amps to around 3.4 per cell or less so you would be getting 2800 watts or 3.8 hp Cheers Quote Link to comment Share on other sites More sharing options...
RCbutcher Posted March 12, 2014 Share Posted March 12, 2014 Im impressed I could not work this out. How would i begin? Hw sc8 120a esc , cc3800kv @ 2 or 3s I have a volt metre but no lipo yet. Quote Link to comment Share on other sites More sharing options...
suicideneil Posted March 13, 2014 Share Posted March 13, 2014 Peak output and real-world output are two different things, but we all love the 'on paper' specs- my Gmaxx puts out about ~500HP per ton Im impressed I could not work this out. How would i begin? Hw sc8 120a esc , cc3800kv @ 2 or 3s I have a volt metre but no lipo yet.You need to know the peak/max current the motor is rated for and/or what it's peak wattage rating is, ESC spec doesn't matter in that regard- Castle don't list that spec for the 1410 motor( many brands don't as it happens ) but they might be able to provide it if you ask nicely.Once you know that, it's simply current X voltage to get peak watts, divide that by 0.00134102209 to get peak HP. If you wanna know HP per ton, you simply divide 1000 by the weight of your model in KG, and multiply that by the HP figure...Unless people still go by Imperial measurements for BHP...
