    Finally got it fly today. It was breezy, but at least the rotors had no trouble spinning up. Here is the proof. https://youtu.be/xfY3FSSsagQ?t=100 Thank you for your help. It's fun!

    That's great! Shape A will be easy to do. Thank you for the clarification.

    Should I shape it more like A or B in the picture? Or should I make it thinner, like the "Typical Section" in the plan? Thanks.

    A question on the wing stub: The plan depicts its cross section in an airfoil shape, while in the photographs the wing stub looks more like a wedge with rounded corners. Should I sand the wing stub into an airfoil, or just round the corners and leave it as a wedge? A wedge will retain more woods, thus makes the wing stub stronger and more rigid. How thick should the wing stub be? Thanks again.

    Got it. Put the wedge on the top and align the axle to the bottom. Thanks.

    Should the rotor axle be perpendicular to the top surface of the wing or to the bottom? From the magazine pictures, it seems that the control-horn mount is aligned to the wing bottom, while the motor-case mount is aligned to the top. There is about 10 degrees of difference. Thanks.

    Pick a receiver small and light. Range is not that important -- For such a tiny plane, you will lose sight of it long before it gets out of the radio range. I happen to have a Spektrum AR6115 at hand for this project. Happy hacking!

    For my first build, I decided to get it into the air as soon as possible, so no paintings, no carbon reinforcements, and no dihedral adjustments to the wings and the stabilizer. I applied the stickers for the colors and as a cheap way to stiffen the surfaces. The plane ends up very nose heavy. I had to add 20 grams of tail weight for balance. In hindsight, I should not place the battery so forward. Maybe I should have run it on a single-cell lipo. Because of the incidence reduction, its GC is about 1 cm aft of the original position. The pitch is still stable with this new incidence-CG combination. Don't know how the flight compares with the original configuration. All up weight, including the 20 grams of tail weight, is 133 gram. (The original 5 gram nose weight has been removed.) It needs more than 10 mph of wind to fly. It penetrates ok, and gets small very fast, maybe due to the weight. It prefers to make wide, smooth turns, like a jet, again this maybe also due to its high wing loading. I think it should be lighten up. It tends to wave its wings. I think removing the wing dihedral not only makes it look more scale, but will also improve the flight performance.

    Well, once I was told that for the PSS type of gliders, the incidence of the stabilizer should align to the flat bottom of the wings, so before I read Phil's reply, knowing no better, I had adjusted the stabilizer incidence accordingly, which involved shaving off the foam above the stabilizer, and filling up the resulting gaps below. This is how I arrange the gears. I link each side of the elevator with a separate carbon rod. The battery is E-flite 200mah 2S, commonly used in their micro planes, like UMX Beast.

    the gap is later filled with foam

    Also, do you keep the original incidence and CG for free flight?

    I am doing my own Alpha Jet conversion now, and I have one question: How to remove paint from the black canopy? Thanks.
