SPAD
Simple Plastic Airplane Design
The Derelict. This is our third design entry for an RCCA legal open "B" class plane.
The main difference in this design is the choice of materials. We use 2 mil
Coroplast® for the wing, and the fuselage is made from a light weight, smaller O.D.
gutter pipe. All up flying weight with a Magnum® .25, three Hitec® HS-81 servos
and a 270 mah battery is 2 lb 4 oz! The Derelict is our best flying open "B" class
design yet, and boy does she fly!

Type: Combat
Wingspan: 36"

Summary of Contents for SPAD Derelict
- Page 1 All up flying weight with a Magnum® .25, three Hitec® HS-81 servos and a 270 mah battery is 2 lb 4 oz! The Derelict is our best flying open "B" class design yet, and boy does she fly!
- Page 2 A Dremel® with a cutting wheel works best for this. There in NO down or right thrust on the Derelict. If you are using full size radio gear - see the note below, if not, procede to step 2.
- Page 3 1/2" in front of the leading edge mark and a 1/2" aft of the trailing edge mark you made earlier. If you build the Derelict per plans, and you use full size gear, you will have an extremely tail heavy airplane that you may not be able to balance correctly! 2) Drill for, and install the 4 1/2"...
- Page 4 7/8" wide, you will notice an increase the overall speed of the Derelict, while retaining it's outstanding turning ability! So if you want to gain an extra speed "edge", cut the yardstick down to 7/8"! 5) Test bend the wing top panel over the spar.
- Page 5 NOTE: Your engine and gas tank should already be mounted at this point. USE YOUR RADIO EQUIPMENT PLACEMENT TO ACHIEVE PROPER CG. Your Derelict MUST balance level to slightly nose heavy at the wing spar. A tail heavy condition is not acceptable, and is VERY unsafe! 1) Glue the elevator and aileron control horns in place.
- Page 6 5) Fuel up and go kick some serious butt! As always, send pictures if you would like to show off your plane on the SPAD gallery! And if you have any further questions, please don't hesitate to post them on our SPAD message board ! [S.P.A.D.]...
