I did an RC conversion on the Guillows Zero in late 2005: [link=http://www.rcuniverse.com/forum/fb.asp?m=3713800]Guillows Zero RC Conversion[/link] It's stable and flies very well, as long as you keep the airspeed up and don't horse it around. Doing exotic maneuvers at below half-throttle, or giving sudden, full-deflection control inputs WILL cause it to snap & spin - Kinda like the full-scale WWII fighter planes... Senor Matthews offers good advice about the airfoil - converting to semi-symmetrical is slightly more work but will yield a much smoother flying plane.
I plan on sheeting the wing and fuse in 1/32" balsa, using silkspan to cover the entire model and painting it. I've never used it; will it be strong enough for a gasser?
I sheeted the wing and the fuse back to the trailing edge and ended up slightly on the heavy side. Strength-wise I don't think it needs it and next time (next time??) I'd only sheet the cowling area, the center section of the wing, and the underside of the fuselage around the wing (for landing strength). Over the years I've developed a love/hate relationship with silkspan. I love the way it covers and finishes but hate the way it punctures if you look at it the wrong way. My current fav is koverall, with the caveat that it's slightly heavier than other fabrics so you have to be careful not to glob on too much dope when finishing.
What torque servos have you used on these sized Guillows conversions?
Hitec HB65s for the aileron / elevator, HS55s for the throttle. HS55s all around probably would have been fine, but the HS65s weigh nearly the same and have almost twice the torque.
Thanks for your assistance! I will post pictures as they come along.
Please do!!!
