Ampdraw in Eolo?


Has anybody measured the static ampdraw for the stock Eolo with 8 cells? I have a Kontronik sun 4000 ESC I intend to use on mine. This one can handle 35A cont./6-16V, so I think it will be enough.

I measured 15-16 Amps, 136Watts to hover 1300g flying weight with Astro 020 4T brushless, moderate headspeed. I did not measure maximum Amp draw.

It is my understanding that it is not the maximum current that was causing some problems, but exceeding the maximum current for the BEC causing the ESC to shut down (anyone confirm?). You may want to check the maximum current allowed if your ESC has BEC. 3 Amp BEC is good.

Ok. The ESC I have has the shutdow function disabled. 3 servos is no problem, 4 might work also. Figured it would be good in the heli since it doesn't shut off at all.

Soo, I finally got to do some testing on the Eolo. With a Kontronik Twist-33 / Smile 40-6-12/8x1700scr the static Amp draw was: 75% governor, 4 deg. pitch=13,5 A, 14 deg. pitch=26,5A. Could not measure hovering draw cause I used a clamp meter. The result in non governor mode was 27A at max pitch...hope this is of use for somebody!

Of remarkable use. Thanks for measuring.
I finally know my LiPo pack is safe.

I measured 20-30 amps on 10 cells with the twist 3700 in a hover

hope that helps
