Hi Guys - motor manufacturers!
For years we flew pattern with an OS 140. Now the motor manufacturers come up with equivalent outrunners motors of size 120 or 160 = refer to post #7 above. WHY WHY WHY?
I recently converted to the dark side - Otop. The 160 outrunner is to big, too powerfull and way to heavy . The 120 outrunner is not powerfull enough although size and weight are good. Most guys here in SA using the power160 outrunner love it but say they only using half throttle most of the time.
Why is there no 250kV 140 equivalent size outrunner out there that can take a 10S battery setup?????????????
I am current weighing in at 5.2kg in my Otop with a 120 size equivalent motor (63x56 can), 10S 4400 15C lipos and 100A HV speed controller all from a cheap source because it was purely experimental for me. Averaging about 2800 mAh per intermediate flight ... max amps of about 60A and average around 35 - 45 Amps for the flight. running a 17x10 APC-E prop.
the cheap motor is heavy - if there was an equivalent 140 size outrunner from a reputable manufacturer that weighed the same or less I would go for it like a shot...
Neu has some direct drive inrunners that can easily handle 10S and are in the 240kV range. I've been very eager to see how they do and am contemplating getting one this winter. There's a 16oz and a 20oz motor (also a 14 but probably gets hot).
They are the 1900 series motors, 1917 and 1920 I think.
I'm running a Scorpion 210kV on 10S and really liking it. Max current is low though. 19x12 would be the most it could handle. 18x12 is pretty easy for it. They make a 250kV motor too, but over rated. 17x12 was OK, 17x10 is probably better.
