Which one you think the better for the job; Castle 90 ESC or Cobra 100 ESC ??
You know, these advertisers don't compare apples to apples when they advertise, and I'm having trouble figuring out which ESC will give more bang for the buck. The Cobra also has a higher rating, while the Castle has a heat sink. I assume the Castle is a switching BEC?..... but they don't say at what Volts and Amps.
I'm going to be using a 4120/14 class of Cobra 710KV motor pushing a 13x8 , or maybe a 14 x10 prop with a 4S 5000mah to a max of about 900-950 Watts with 55-65 amps. Most of the time I'll be at 1/2 to 2/3 throttle. But the problem is that it's hot as hell here in Houston, and less heat build up occurring internally will help overall. The plane will be a 8.5 - 9lb Kadet with about 7-8 minute flights.
