"WHAT an AIRPLANE!!! It does everything you claim... and more! Snap rolls are great, just need to up it into near stall, and have LOTS of rudder. Knife edge is at 1/2 throttle...(keep working the ailerons though... it wants to continually correct itself). I like to point it straight up, go hands-off, and watch it grab level flight at the stall point. The only place one has to work with the I-wanna-fly-upright tendency is keeping steady inverted flight, and the knife edge. I kept going with power for knife edge, as is the usual plan, and found it trying for knife edge loops! Needless to say, it's a ball to fly! Not just an airplane to point and slam around, but to actually FLY.
"I put in a YS .91 four-stroke, extra size for our "weak" mile-high air. The power is perfect, but I ended up still nose heavy, even after recessing the Du-Bro iso-mounts a full inch back into the firewall (though this is only 1/4 inch back of where your plans show the Saito .80). Hurt my pride to have to add weights to the tail, I've always been able to plan ahead to let the battery do the trim... oh well. Even so, and with trike gear and all, it came out at 10 lbs. 5 oz, not too bad.
"Thanks again for another fine design... I'm still flying my Venture 60, on its second engine though..."
