As much as I hate to do it, it looks like I'll be mounting the tail servos behind the trailing edge bulkhead. That moves an already aft CG further aft. I really hate having to add nose ballast but there's just not enough space to move things forward. The compartment over the wing is full with the aileron servo/linkages and receiver/wiring. More headscratching will be needed for sure to get it all in there and working in such tight quarters. That's often one of the toughest challenges with small glow planes like this. I've toyed with the idea of a 4th channel for a throttle sleeve but it's not looking likely at this point. I actually bought a new Pee Wee .020RC recently just to rob the throttle sleeve for this TD powered plane but that may have to wait for another build.
