Sorry, didn't take any pictures. The receiver was installed right behind the wing mount bolt plate. Get some Velcro that sticks to itself. The kind that's smooth on one side and rough on the other. This type of Velcro uses no glue and is normally used to secure things like garden hoses or extension cords.

Work with fuselage upside down in your work cradle. Attach one strap to the wood cross piece at the rear of the wing opening. I use an ice pick to punch a small hole in the Velcro. Install the strap with an allen head servo screw. The forward strap is installed under the rear of the servo mounting plate. I took a piece of 1/8" ply and cut out a rectangular piece about 1.5" x .5". In the center of that piece, I glued another piece of ply about .5" long. Drill a 1/16" hole in the center if the mount plate on the vertical face and install the other piece of Velcro. You'll end up with a Velcro strap attached to the rear of the wood mount. Epoxy the mount assembly with the strap facing the rear of the plane, just under the rear of the servo tray. When the glue is done, wrap the receiver in a wrap and Velcro it in.

I put a piece of foam on each end of the wrap and used a small nylon wire tie to keep them in. That'll keep the receiver from slipping out of the wrap.

Wrap the battery in 1/4" dense foam and push it down into the space between the cockpits. Install the rudder and elevator servo's and you'll find that the servo's will keep the battery from falling out.

The engine was mounted to the stock mount at the original location. So far no engine thrust angles have been changed. The model flies fine.

The ailerons are hooked up as flaperons.

Don't mind helping at all.
