I have a buddy that has one of these EXTACES ,(i sold it to him built ) it went together very easly . and its very light .
I had a chance to fly with him today , and i got to say it is BIG FUN !!! slow flyin,hovering ,torque rollin FUN
Hes got a OS 91 FSR on it , I dont think you need this much power BUT too much power is part of the fun !
i will get him to post some specs and comments on it ...
