The motors fit thru the dummy radial with 1/8" clearance. This will funnel most of the cooling air into the motor itself.
Here the M A 16x10 prop is holding on with a truturn style A spinner. The spinner adapters and spinner bolts needed work before they would fit each other for this application.
The spinner came with a steel backplate that replaced the prop washer. I used a great planes spinner adapter but it needed to be cut before the spinner would fit.
Motor mounts are 10/32 titanium with aluminum spacers. Here I was looking at the opening for cooling air being blocked by the wires.
With the esc behind the firewall the opening was enlarged and sealed with 30 min epoxy and microballons.On the side are 3 new holes for the motor wires coming from the esc.
Here the 80 amp esc rests on top of 1" long dowels epoxied to the firewall and screws in the mounting tabs.
With the center wing on I started lining up the stabilizer.
Wetting the balsa with epoxy before laying down some cloth.
With the cloth applied a layer of plastic is left on while the epoxy cures and a little over lap here from the top and bottom strip.
