donkey doctor,

Thanks for the info on Tyvek covering! Going to do some experimenting now. My SB lasted only about 10 or 12 flights. Great flyer with my Magnum .30fs. I let a friend fly it and he didn't see the need to throttle back after take-off. One lap around the field and in a very shallow descent at full throttle the horiz stab went into flutter and ripped off.......instant lawn dart! I will build another eventually because it is such a fun plane to fly.
