RE: Re: Kang's F1D Plan

OTOH Larry Coslick has some models with 70% of the stab area on the left side. The purpose was to induce extra stab tilt under high torque launches in low ceiling sites.

At my last flying session at St. Lukes I tried to get my F1M to fly in the high part of the room. It took all day to accomplish that which I did mainly by increasing stab tilt (had no other choices available). I'm not sure if added stab offset will be the answer for the low powered parts of the flight but it's worth a try.

 

 I think all of the lifting surfaces should be larger on the inside of the turn than the outside.  Flying with the wing level (without banking) is efficient.  I saw that Kagan and Sanborn have 0.5" stab offsets on theirs.  I've tried stab offset on a couple of my EZB's, and I didn't like the differential forces that would tilt the stab a lot at launch.  So I copied only half of the offset.

Pretty model. Why the stab offset?
