Glen,

I think that's what I will do as well, make an oversized spinner backplate from ply and then the angled spacer and somehow anchor it to the model's nosering with the firewall attached to the motor. Seems a little gymnastics will be involved, but that appears to be how some others are doing it on various models. I did find and download the firewall pattern posted on the F3A Electric discussion group. Good info also found on the RCU Valiant thread.

This is my first electric 2-meter pattern ship (and composite as well) so I am venturing into new territory here.

The composite firewall and servo tray material arrived yesterday from ACP. I got a couple sheets of both the end-grain balsa CF laminate and the nomex honeycomb laminate. A long-time pattern guy and friend of mine gave me some pointers on these materials last night at our club meeting.

The aeropoxy is arriving in the mail today which means the next couple of weeks should be interesting.

How far along are you on your assembly? Thus far I've gotten the elevator and wing servos installed and linkages done on the elevators. Elevator linkages were a bit tedious, but the the aileron links will be easy by comparison.
