For the 3520.
From their specs, on 15x5 props, they are showing 100% throttle at 18.1 amps draw.
.... 16x5.4 props, they are showing 100% throttle at 22.2 amps draw.
.... 18x6.1 props, they are showing 100% throttle at 30.2 amps draw.
16" would be the maximum prop size I'd use for a quad, so I'm looking at the 22.2 amps wondering if I could SAFELY & RELIABLY use some 40amp ESC's I have laying? around.
I'm 1 year into the sport and know nothing about KDE. Are you guys thinking theese may be up to par with the Tiger u5 or u7 or the Avroto 3515 or 3520?
40amps is more than enough. 22amps is max throttle, I am sure you're not going to full throttle for more than 10secs at a time. Average you'll probably only going to pull 8-15amps.
As for KDE, they have been making high performance Helicopter motors for a long time.
We will have 4014, 4012, 3520 in stock next week. I decided to carry them after seeing the Dynamic balancing...
