Huston, we have brushless
Well,
The Hacker A-20 is installed on my Formosa and has survived two flights without incident. It was waiting for me when I got home, and within 48 hours was in the air. I had to fix up the nose after the tree incident, so I glued two vertical balsa strips of 1/4" square or whatever GWS uses to mount the motor on.
It took awhile to figure out how the prop stuff works. The can of the motor spins, so one mount just puts 4 screws into the can. On the other side, the prop adapter just winches on tight when you slide it on and attach a prop. I mounted the motor so the but of the can sticks out because it seemed best to keep the motor cool and I didn't want to mess with digging out all that foam. It seems to be working great, though some better mounting screws would have helped.
I'm not going to go crazy on painting this plane either I've decided. I might still do some one color stuff for identification purposes, but not as fancy as I thought at first. I'll wait until I go balsa to have a really slick plane.
Anyways, she doesn't go vertical, I think I'd need a gear box for that. A 10 x 3.8 SF will get her very close though but I think the draw is too much for the motor and battery. I didn't measure it but after awhile the can and battery were hotter than I want. I put a 9 x 4.3 on it, and it draws 14 amps static. More than I wanted but within specs of both. I fly half throttle most of the time, and I can fly at 1/4 or less now, plus that's static draw, so I should be fine. I haven't figured out maximum flight times, but I will soon. I just wish I could get her to knife allot better.
Well, that's enough for now.
