RE: Sig Hog Bipe - feedback?
The mods I suggest are pull pull elevator AND rudder. Glassing both wings wider than the fuse and of course dual aileron servos. I fly a .91 OS four stroke. It will hover if you concentrate but not low. It will provide a nice upright (almost about 30 degrees nose down) flat spin on command and easily recover. You definitely need a shock mount. Its the shark bipe on page four of fubar hill websits.
