The three blade props arrived in the mail today (sheesh they're crap quality) but decided to spool them up anyway just to see. Despite a very gentle launch, she shot straight to the ceiling and sucked herself there and I stupidly cut the throttle far too much, and she fell to the floor. The rigid plastic mount the gimbal attaches to snapped on one corner. So stupid. But I have finally broken something other than a prop. Now to train myself NOT to cut the throttle (nor to fly it indoors when experimenting). Looks like I'm going to learn about gimbals next as I fix this little problem. Breaking things sure makes you learn about how to fix them.
