S-Tee mod for symmetrical wing
My intent is to transform an S-Tee kit from relaxing park flyer into a pattern/stunt plane by replacing the standard flat bottomed wing with a zero-dihedral fully symmetrical wing designed and produced by Doug Hart at my request specifically for this experiment. I may also try enlarging the control surfaces to enhance 3d flying characteristics. Here's how that turned out. Thanks, Doug, for the custom cut.

Now to the fuselage modification. The Hummer wing has significantly less chord than the stock flat bottomed S-Tee wing. Doug said S-Tees tend to be tail heavy anyway so I should mount the Hummer wing at the BACK of the S-Tee wing saddle to help with balance. Therefore, here are my fuse mods for the symmetrical wing.

And here she is. The smaller chord Hummer wing is set at the rear of the existing wing saddle to achieve balance and it's STILL a bit nose heavy but once I get her trimmed out, she should be a fun flyer.
Final Word: S-Tee mod for symmetrical wing
Flight on 2s with a 6x3 prop was sluggish at best and overall unsatisfying. Switching to 3s power and a 5x3 prop made a world of difference and also solved a secondary problem = since I have a simple tail skid rather than a tail wheel, the plane wanted to careen wildly left on power up for takeoff. The 3s/5x3 prop switch greatly reduced that careen left tendency. The heavier 3s battery also solved a minor balance issue. Finally, after a minor tweak of control throws and expo amounts, I have it flying the way I want and I'm quite pleased with how it turned out.
