thanks for your replies scale dreamer and skyking.after looking more closely at the edge,i think i was in error about edge having a belly pan as it is a mid wing.john ;keep me posted what size prop works best with the 91 .i'm assuming you have an os fs 91.how were the instructions for the edge?
I;ve read a lot of posts on the vector 300 extra and i'm curious as to the flight characteristics of the edge vs. the 300s .about same or totally diff.Is the extra more aerobatic?i've been in the hobby a lot of years but i am only now getting into the extreme aerobatic type.

thanks .ken
