Fred just ask away.
I built my TM back in 2007 also. I have a 45 st in it and it's a great flyer though I crashed it awhile back and have never repaired it though now I may have to start working on her again.
My Decathlage was -1 on the top wing to the bottom.
With the ST 45 I can get this plane to really flatspin.
Ground handling is very sesnitive due to the narrow landing gear.
On take off hold a little elev and slowly advance your throttle while easing off the elev. by the time your at WOT you can pull back on the elev and your flying.
If I remeber correctlyu the CG is at the rear of the cabane.
