The reason the option to put the elevator servo's in the rear was to solve problems like yours. Why not use it?

Doing this would be off setting about 25 ozs. off the nose. Hard to beleive this would not be enough? Hmmmmmmmmm!!!!

Now you have me worried cause I have a DA50 up front with a Slimline smoke system. Thinking I may have to put the rudder servo in the rear with the elevator servo's.

Luckily, that option is also there. Is yours the ARF or ARC version?

Please keep us posted as to how you resolved your problem.
