My miniTitan was repaired and had a new ESC. Time for the first test flight. After a minute of hoovering, I shortly pushed full collective to check the governor. The headspeed dropped, not surprisingly since the governor is set to it’s lowest setting. So I pushed full collective again, to see if the governor is able to compensate.

Went flying after dinner, the wind had calmed down and the rain had stopped.

I had some trouble starting my Raptor (glow heater indicated only 1A instead of the usual 5A). Since it’s been a while since I charged it, the battery was dead. A few minutes at the charger solved the problem.

In the mean time, I took my miniTitan out. Did some flying back and forth and a few stall turns to regain confidence. Next I did some back-flips. This is where it went wrong. On my 3rd back-flip, I intended to keep the heli inverted for a second and continue the back-flip, but the ground intervened…
