Ralph,
I have a Homelite 30 on mine. It originally had a early type Zenoah 23 (Kalt 22) engine but was under powered. Sure seems to have plenty of power now.
Mine is a little on the heavy wing loading side. On landing, I bring it in with plenty of speed and left the speed bleed off with the plane close to the ground. It stalls at a faster speed than you would think.
On tank off, keep it on the the ground until you have good flying speed. With the big engine it will jump off the ground early before you have full control. For this reason, I would not put the scallops in the control surfaces. Leave them straight.
Up in the air it is like a smaller stick.
The Bridi Stick and the Old Timer are the same plane. The only difference is the name on the box.
