Some time later and a lot of trials and errors...
Thanks for your interest guys...
Two fundamental things: the plane IS tail heavy and the plane drops the tail, even when balanced, while standing in the mains in a trycicle configuration.
So... after a lot of trying I figured the following configuration:
Engine is planced 7/8" ahead of the recommended configuration. Also, a 2 1/2 ounces brass spinner is used.
That balances the plane to the point that is indiferent to drop the nose or the tail.... The balance point is as the manual recomends, 3 7/8 " from the leading edge.
The plane still drops the tail in the ground. Took out the main (wing mounted) wheels and bent them back a little (perhaps 1/4") and now the plane stays on the 3 wheels... but not too much... if it hits a bump will drop the tail. I assume that when the 12 oz. fuel tank is full it will help when taxing and taking off.... and... when landing, then it will have a "natural" flare...
I have built the Tiger 60 from a kit (this one was an ARF) and had the same characteristics...
Still, you can't beat the way they fly...
Now, about flying it... hey, I live in Montreal... we still have about 15" of snow in the ground and not telling you the wind-chill factor... Will wait till May!
