RE: .60 sticks?
Thats a nice photo BT. You guys are making me want a larger stik.
I did go fly my Sweet Stik today. It was rock solid in the air. I never even switched to high rates. I just did a few loops and rolls and mainly just cruised around. The rudder response was excellent. I use rudder a lot and make lots of turns with just rudder and elevator. This plane turns with the rudder like a 3 channel plane with lots of dihedral. I was worried since its a little on the heavy side that it would land fast. It didn't. With almost no wind to help it still came it at what would be good high wing trainer landing speed. Very controlable all the way to touch down. It landed as slow as my buddies 1936 gas stick model (basicaly a swizzle stick) and my plane is at least a pound heavier.
Now that the engines have been tuned and leaned out they start with just a bump of the electric starter. They still won't start by hand. I got my head leak fixed by just tightening the head bolts. I took the head off my buddies engine and cleaned it good and put it back on and it still blows bubbles pretty bad. We may send that one back.
I have never owned a gas engine so I am not familiar with the displacements. But isn't a 20cc the same as two 60 size glow engines in displacement? If it is why would you put that much (or more) engine on a 60 sized plane? Do they not put out as much power as a glow engine? I like the idea of having a spark plug and being able to use gasoline for a fuel.
