All great info guys.
I agree with cfircav8r that I should try one thing at a time. I have moved the rudder servo to the tail and adjusted the CG at 4.125" from the LE at the fuselage as the manual for this plane recommends.
I flew this plane in the past with a YS 110 and it was great flying and landing, but with the cost of fuel I decided to change over to the DLE 20 gas engine. I have to admit that I just did a quick finger tip level test of the CG after installing the DLE. The plane did seem a bit nose heavy at the time but I have flown planes in the past that were noes heavy with no problems so I thought this would be ok (but it seems that maybe this plane does not like it). After doing a proper CG test I can see that it was out enough that I had to move a servo to the tail.
I will try the plane with the new CG adjustment as soon as the wind gives me a break (soon I hope). I'll let you know what happens.

Thanks guys.
