Acrobatic radio-controlled aircraft Satan

The Satan plane is of my own design. I based on the dimensions of Extra Chaos or Su-31 from Hacker. The goal was to make a plane that would be suitable for aerobatics or even 3D aerobatics. Hence the need to control elevator, ailerons, rudder and engine. The plane is equipped with AXI 2212/20 engine. I was hoping that the weight would not exceed 550g, which it didn't, but no matter. Propeller GWS 9x4,7; 9x7-static power 13A Li-Pol E-tech 3s1700mAh HP battery. 3x HS-55, small 4-channel hitec receiver

I generated the wing profile from PC and drew the plan in Autocad.
Span 1000mm length just over 1000mm.
The wing and tail surfaces are structural balsa. The fuselage is made of two 20x5mm thick spruce strips with the wing in between, and the rest of the fuselage is 20mm polystyrene. The plane flies very slowly indeed, perhaps too much for me.

The wings.


I glued the balsa with Kanagon, the spruce strips that form the fuselage skeleton on the fuselage with epoxy and the polystyrene with Purex. The wing is glued with epoxy, the elevator with Purex.


Ailerons and tail surfaces.

Finished Satan aircraft.


The ailerons are glued with fiberglass tape and the tail surfaces are each on two plastic hinges.


The servos are taped and taped to the fuselage with polystyrene.


I made the levers on the directional surfaces out of 1.5mm plywood, it's quick light and cheap and I can make them exactly how I want them.



I completed the aircraft in early September 2005 and the first flight was on 4 September . While flying it the elevator stopped working-my cable fell out and this is how it ended. I started fixing it that day.
5.9. 2005 was the 2nd sortie, but my ailerons stopped working, probably a loose cable in the connector. And the same day in the evening there was a complete and successful trip.
The plane is capable of sucking up with the propeller, which is a GWS9x7, I haven't done much yet.

Suggestions for improvement after long experience

Longer snout. Taller fuselage, both at the rear and at the bottom to protect the rudder more. Data servos aft surfaces closer to the center of gravity and use some thicker than HS-55 (HS-55 is sufficient for the wing). Maybe a narrower wing profile if the Satan should be faster at full throttle. Smaller control levers on the tail surfaces.
