Flew my Plank this morning then hit the ground very fast

I pulled out my Plank wing, replaced 1800kv motor with 2217 2700kv motor and 1100mah battery with 1800mah. Flew right out of my hand, very fast and smooth then started doing loops and rolls, went into death spiral and boom. Surprisingly, the wings just separated from the fuse, the motor shaft got pushed back a bit and the casing of the rx came apart but it all fits back together. Couldn't find prop or prop adapter. Crashed not far from an automobile so am thinking I need to test this out on the island where there is nothing to hit. Wow, flying it felt so smooth and effortless - and it looks cool in the air. I thought as I was walking to pick up the pieces that there wouldn't be anything left but epp just bounces. Have to rebuild this one.

Figured out why I spiraled in, left screw out of servo arm and right elevon jammed all the way up when I was slamming it around. - so my theory goes. Bent motor shaft a bit, motor probably wont last long as I will fly it anyway. Don't have any straight shafts.

Took about an hour to get plank back together. Ready to fly tomorrow.
