RE: Kangke F-20 / Rossi 53 trashed
I crashed mine too, I thought I had a radio interference and it rolled over on it's back and did a nice figure 9. Turns out that radio is on it's way to Illinois for a look-see.
I had to beef up the tail/stab connection too and am still working on getting it back in the air.
I also learned a high visibility paint/covering scheme can help..it doesn't take anytime at all to lose perspective, top to bottom, etc.
When and if you rebuild it...add a decent size fuel tank and beef up the nose gear mount.
good luck...it's a bummer though.
