FlyEng,

I think you will still be able to achieve CG with the elevator servos in the tail as long as you use the "midi" size digitals. I don't have the ignition module and Rx batteries as far forward as possible. I don't like that hard-to-reach space between the firewall and the first former, but could have placed stuff there if necessary.

Definitely want to use pull-pull rudder, however.
