Boeing Bird of Prey

Spencer said he modelled the Boeing BOP and it was a failure. There was insufficient yaw stability. He wanted to try again and asked us to join in. Each produces his version and lets see whose gets to fly.

 

First off, it looks ugly. This is how I might do it.

Fuselage

This component will provide lift and house all RC gear and a Turnigy 1811 motor will be mounted as a pusher, driving a GWS 5"x3" tractor prop.
This will be constructed of a rectangular piece of blue foam: 28" x 5" x1" thick. Hot wire cut the section. Sand to shape, cut the slots, pockets or grooves.
Motor is mounted on 2mm ply, secured with nylon tie (don't intend to do any thrust adjustment), epoxied to a slot in the rear of the fuselage.
The battery, receiver, esc are mounted as far forward as possible and side by side if the wires are long enough.

Wing

A rectangular wing, acting more as a stabiliser, to be shaped and cut from 3mm balsa sheet or 5mm compressed foam (which then has to be suitably stiffened). Length of 30", chord of 3". Hinge the elevons, make score lines for the wing tips and fix that to 90 degrees. Cut out a V-piece from the inboard section and join the two wings into a swept back wing with dihedral.
Connect up to the 2 elevon servos in the fuselage, use wire in plastic tube.
