Hi guys,

Finally, I could draw some lines, according to these principles:

- Easy and fast construction. This is a foam-plywood hybrid, and it uses a fiber glass boom, and possibly depron or Coroplast tail surfaces.
- Good-looking, I'm tired of box-shaped gyros!
- Rotorspan, about 88cm. That's because blasa comes in 1m planks, and my DC giro uses just 0.54m of that plank, so this is the perfect excuse to make something with the many 40cm long blades I have lying around.
- Lenght, 72cm (28").
- Height, 17-18cm including rotor system (the fuselage itself is in the 14-16 range).
- Max width, 7cm (2.8").
- Hang angle, 5º.
- Rotor mast angle, 10º.
- DC control (5-6º sideways, 8º front-aft), throttle, maybe rudder.
- Tricile landing gear. This made me draw a small winglet, whose main purpose is just hoolding the landing gear.
- CG falls just before the winglet. I've drawn things so that most important forces are algined with the CG; however, servo and batt location may fool this a bit.
- Generous side area. Oh, before someone points it out, yes, I have to increase the blade clearance in the tail...
- Norvel 0.074 for power, HS-55 servos.
- This project's name is "As de Picas", the spanish for "Ace of Spades". I prefer to use my imagination for the drawing thing

A side view...
