That is totaly cool, it would be awsome to get some video also. How does the plane fly with that mount, I bet it slows down really quick.
I saw some cracks in the covering on my electric, turns out I cracked the fuselage in half in two places. I dont think this plane was intended to do blenders. It was funny because I flew at around 9:30 am and then again at lunch time and at lunch the trim was different and I noticed that knifedge was using more rudder, but overall the plane was still flying nice. Good thing I didnt do any blenders at lunch. I broke an Eflite YAK-54 in half doing blenders, it does a better blender than the HL Extra but its only good for about two really good violent ones. The blender when done properly exceeds the speed of foam.

I will stop doing blenders with these little profiles they flex too much and dont have the inertia to really flat spin anyway, but it was looking really cool spinning it into an inverted spin, the palne does stop falling it just doesnt get into a good flat spin.
