Well went flying again today 6/11/08 i busted the 20/10 jfx on a landing, came in a little hot landed in the grass instead of the grass.. So i pulled the tail wheel off and that made the rudder flip up and wacked the prop just on the edge of the runway(paved) .......So it busted the prop, i put a apc 20/10w on it today at idle its 1400 rpms and full power its at 6100 rpms...... I've got a xoar 20/10 for it to try next i'll post what it is along with the weight next time i go flying!
