Propellars,
I've got fifteen flights on my Reaper so far with no problems. Mine weighs 171/4 pounds dry which equates to about 21 pounds at takeoff. I've got retracts and when I fly, it's mostly full throttle and lots of high-G manuevers. With the retracts and my MW54, I would guess the top end at around 130 m.p.h. When I first saw the wing set-up, I too was a little skeptical. But I built it stock witth no modifications there. As far as flutter goes, if the wing comes loose enough to flutter then you're probably way out of luck anyway. Incidently, when i built mine, I elliminated all the counterbalances on the control surfaces with no ill effects. My control surfaces look "normal"!

Regards,


John
