Title: T-Square C/G ?
Post by: builditright on June 14, 2011, 07:41:08 PM

It has come to our attention that we have forgotten to include a C/G location on the T-Square plans and after some checking we come to the realization that we need a little help in finding out the actual C/G location for the T-Square, so the ? is... does anybody out there know the what the C/G location is for the T-Square?
Sorry for the mistake.

Walter,

I checked the original Sterling kit plans. Curiously, no CG is given in either the plan sketches or text!

When I built my Sterling T-Square as a teenager, I just built it and flew it.  Never worried about the CG.  McCoy Redhead .35.  It was a fun plane to fly and got me to doing quite a few maneuvers.  As stated there was no mention of a CG location. H^^

Guys,

     As a kid I don't remember anyone whom I flew with ever worrying about the c.g.  We pretty much just
built our planes and put the engines in where the plans showed.

     However, I gotta tell 'ya after flying Ringmasters, I had one wild ride when I bolted my Fox Stunt in a
Flite Streak.  It was touchy and all over the place!

     Best regards,

Yeah, remember my first Flite Streak.  It was a little more responsive than the old Ringmaster. H^^

As a flying wing, the "T Square" should enitially be balanced about 15-17% of the chord. It can be adjusted for flight preferences after that first flight. H^^
