Phoenix 45HV cutting the mustard on an XL-E!
I couldn't stand staring at my 99% complete XL-E (waiting for the Kontronic Jazz), so I grabbed the hv45 from my experimental electric falcon for her maiden. Just basic low hovering and some short climbouts and everything held together. I then plugged in the eagletree data recorder to see what the numbers looked like.

hover amps: 15A
peak power: 1.9hp (converted from watts)
peak amps on climbouts: 40A
average voltage (from 14s A123): around 40V

Motor (actro 32-4) temp: just warm to the touch, probably around 105-110
blades: 710mm
AUW: around 10lbs.

It looks like a megabuck controller may not be needed for the XL-E. BTW, this 45hv has been in service for about a year with no issues. Running old firmware at that. My falcon was even stuck tree (how ironic, a "bird" stuck in a tree...) for a month before I could get it down.

I think when you start doing high harder 3D stuff you will pull more than that CC45 can handle and I would hate to see that beauty destroyed because of that! BE CAREFUL....RonTeam MikadoUSA 480XXTreme, 550SX, 600SX, 700XXTreme, 800XXTreme!!

Thanks for your concern. I'm only doing 2.1D at the moment :^)
Wouldn't an 11 degree pitch climbout be the most current you would ever draw?

The thing takes off like a rocket, BTW.

Yeah but if you couple that with forward or aft cyclic, you will even more!Team MikadoUSA 480XXTreme, 550SX, 600SX, 700XXTreme, 800XXTreme!!
