Motor Specs Question
Hey guys, I'm trying to learn more about brushless motors and how the batteries voltage affect them and max RPM's, current draw etc...and was hoping someone can share some experience or knowledge on the specs of this motor. I have used 2S on it and maxed the gearing out on 2S, being that a bigger pinion won't fit (2WD ECX Torment- 23T Pinion -Stock 87T Spur). I'm sure I could run the risk of meshing properly and really squeeze some more teeth in there but...why risk it? LOL. My question is, being that this motor is rated at 5200KV, even tho the ad says it can handles 2-4S, would the motor be at risk of KABOOM because of such high RPMS? Being a 3650 sized motor, from what I've read the max RPM "safely" on these is approximately 50,000Rpms, 3S would give it just above 60,000 Rpms. Has anyone had experience with this, and if so could you share some knowledge in how to read the specs provided? I maxed this thing out at 79km/h so far...few more runs to make sure before we go 3S IF we even can or SHOULD. I have had 4 full throttle passes on this back to back with 2S and she only gets to about 125 deg F.
Cheers and thanks in advance,
