Yeah i tryed the 12.25x3.75 prop and the plane was like it was something else...It had more speed than the 11x6 i was using and was going to try a 11x5 but she hit the ground..wing is good to go again but the rest is in the bin,the wing only came apart where the epoxy was(it ripped 1 layer of ply apart)and it was a clean break.

The crash came from a straight down continual snap roll and got a bit low to the ground and pulled a bit more elevator on to get it up but it just made it snap more and in she went at about 3/4 throtle...Dont have any more 12.25x3.75 props at the LHS eighter..
