I have a new wot trainer and have to admit the quality is very poor. I am about to spend my 3rd weekend on the so called artf problem after problem.
Wheel bolts to long and need a spacer 2mm.
Wing spar too long needs cutting.
Servo tray not square and holes in wrong place to line up with servo snakes ect.
Retainer nut on fuel cover not glued (fell off).
Covering peeling away in 8-10 place. And many more issues....
DO NOT BUY A WOT TRAINER....
