Penta rotor takes flight


Decided we're not going to have enough time off in daylight to work out the solvable bugs, so the first flight was at night. She did indeed crash, but is still holding together. The standard crash is to flip over nose first during takeoff. She also tends to roll over sideways as expected.

Takeoffs require gunning the throttle with neutral pitch & pulling up as soon as the nose lifts off. Takeoffs always start with a nose dive. There isn't enough power to take off with the aft rotor pulling down. Once airborne & trimmed, flight is like a normal copter. Landings R easy. There's no dreaded roll/yaw coupling. That was a test stand artifact.

Yaw control without any wind is the same as the quad rotor.

4Ah 20C is not eough. You'll get 1 minute at a time. Landing gear probably has 2 more battery sets left before it falls apart. Couldn't get any GPS locks with the uBlox. It's either damaged or someone is using 1.5Ghz.
