Hello Dave

I have a Leo with a TT120RP installed in it.
The plane flies quite well with the stock settings, but the CG needs to be moved back a bit to make it fly like it should.
It rolls on a line and stays in knife edge using rudder only. Spins are easy, you don't even have to use aileron.
Verticals are not a problem if the engine is in the right mood..
To be honest this engine is a piece of crap.
I aready had to repair the pump (airleak at the high pressure side) and replace the screw that holds the rotating part (barell maybe?) of the carb.
I'm using a MenzS 15*10 and it's adequate. I had to install bigger wheels to take off from grass, but if you have a paved runway the original landing gear will suffice.
Because of some deadstick landings in tall grass i had to rebuild the area holding the landing gear.
If i knew that it was made of paperlike plywood, i would have done it prior to maiden.
First i had a holder for the exhaust pipe just like yours. It lasted only a few minutes before it parted from the wing.
Now i'm using something that is a lot more elastic.

BTW according to my calculations the CG should be at about 170mm (mine is @ 165mm now with some lead in the tail)
