Excellent documentation Bill, keep the pictures coming. Why did you remove the center composite section? As I have not played with electric before, is the motor mounted off the nose ring, or is it stil attached to the firewall?
Any concerns of cutting the fusalage for elevator pushrod exits? I have used my own version of the DEPS system for my last several pattern planes (actually copied from George Asteris' version) but it has always been installed with the pushrod housings sanded flush to the fusalage very early in construction. I would be a little nervous about trying to do this on a finished fuse.
I removed the center composite section, as it made it easier to work around in the fuse. It doesn't really provide any structural benefit (as it can be bent up and down with ease) and after seeing that Todd had removed his as well, it was just extra weight !! (12 grams to be exact) :-)
With regards to the Motor mount, it attaches primarily to the nose ring, but will be supported by a ring at the back of the engine as well. I haven't decided however weather I'm going to support the ring off of the F1 former, or from a spider web support attached to the inside of the fuse. Attaching off of the F1 former will probably provide better noise dampening, but the spider support, would allow me to be able to adjust the thrust line a little easier.
I'm not too terribly concerned with the exits, because Todd showed me a pushrod exit cover (Hopefully he'll chime in here with the manufacturer) that makes everything clean. Otherwise....yeah....I'm still pretty nervous about cutting the holes. Fortunately the pull pull exits for the rudder are marked on the fuse already.
