YAK 54 Crash during maiden flight
This is my first YAK54 size 40 from rich model after YAK54 ep from B/Horse. I assemble it nicely and checked the cg, control throw before flying and everything seems to be ok. It was nicely taxing and smooth takeoff and after about 4-5 metres high it started to banked to right and as usual, I counter it but nothing happen to the plane. It keep bending slowly and crashed. I was wondering what went wrong, one thing is I fly it without cowling. required engine is .52 4c and I'm using .56 4c, 12.25 x 3.75 prop. Anyone knows what went wrong ? is this because of no cowling install and caused air brake at the firewall ?
