Designed to resemble the Heinkel He-162 Salamander, this plane was built to test the Super Flying Model 2200-9-3500 brushless motor with 1028 fan unit. The V-tail had elevator only, and the nose gear could be steered. The fan duct was made from poster board and doubled as the fan cover. The plane flew but did not have much power because of inefficient duct design.

This plane was built to test the effectiveness of twin rudders on a twin boom airplane. The plane had a single aileron, but the test program eventually ended with the plane being controlled by a single rudder. It worked. The wing dihedral allowed the rudders to function.

The first plane of it's kind for me, it had the Super Flying Model 2200-9-3500 brushless motor with 1028 fan unit and a posterboard duct. This plane also had 60 green LED lights on the bottom. It flew very well and was very fun to fly, especially at dusk.

Designed by my son who was 14 at the time, this plane required some adjustments before it flew. Throttle had to be applied carefully because full power caused the plane to pitch down, but the large wing area allowed good flight at constant throttle.

Yet another in the So series, this one was different in that only the wing was EPS foam, all else was foamboard. This plane was given to my friend for Christmas.

The 29th in the So series, this one was also different in that only the wing was EPS foam, all else was foamboard. This plane was given to my Son for Christmas (and he painted it).

30th in the So series. The wing was EPS foam, all else was foamboard.

Another So plane. This one was constructed from EPS foam for the wing, fuselage, and tail booms (tail booms were strengthened with clear tape). The stabilizer and fins were foamboard. The motor was mounted high above the centerline and incorporated a few degrees of up thrust to compensate. So.31 flew very well.

The 32nd "So" plane. This one was constructed from EPS foam for all, except the tail surfaces were foamboard. The motor was mounted high above the centerline and incorporated a few degrees of up thrust to compensate. This plane is fast having only a 24 inch wingspan. Flies great.

Designed by my son, this one was a noble attempt, but ended up not flying well. It was the smallest RC plane we've made to date, with a wing span of 18.75 inches and a RTF weight of 5.1 ounces. Used a GWS EDF-50.

Another fast So plane. Wingspan 24 inches, weight 14.3 ounces. TowerPro BM2409 18T motor, 8x3.8 prop, 3S1800 lipo. 92 watts per pound, thrust to weight ratio 1.16. Excellent flyer, very fast! All EPS foam except tail surfaces are foamboard.

This plane had a wing made of foamboard reinforced with a carbon spar, and a Kline-Fogelman 2 (KFM2) airfoil.

My second foam board delta, this one was made from two boards with a wingspan of 60 inches. It required 6.4 ounces of lead in the nose, and the battery all the way forward to fly well. At a total weight of 29.4 ounces it flew well and stable with glider characteristics, but when the battery started getting low you could really tell. TowerPro BM2409 18T motor with an 8x4 prop, 3S1800 lipo.

This was a small flying wing using a single flat piece of foamboard for the wing. Uses an 18-11 micro brushless motor with a GWS 5x3 prop and a 3S500 battery pack. Did not fly well.

Hot-wired from EPS foam, this plane was built several years ago for a Speed 400. First flight was November 12. It was recently modified for a brushless motor and flies great. Turnigy C2409-1600, 8x3.8 prop, 3S1800 lipo. Wingspan 36 in, weight 17.3 oz.

Hot-wired from EPS foam. This plane was built many years ago when brushed motors were still in style, and it sat unfinished (I have a bad habit of doing that). Finally got around to finishing it with the originally-designed brushed motors. Flew good but was underpowered.

Based on the Zagi planform, this plane was hot-wired from EPS foam, with the fins and fuselage built from foamboard. Controls are throttle, elevons, and nose gear steering. Landing gear used are the shock-absorbing type from Hobbyking and they work excellent. Uses a Turnigy motor spinning a 8x3.8 prop, 3S1800 lipo, and three HXT900 servos. Flight performance is excellent, wingspan 48.2 in, wing area 458 sq in, weight 22.6 oz.

First flight was January 03, 2011.

An attempt at a lightweight slow flying plane. It was lightweight, and it did fly slow, but also not very good. The name was applied to this plane after the first flight (should tell ya how well it flew!). Hot-wired from EPS foam with a cambered airfoil. Wingspan 33 in, weight 6.1 oz.

An excellent flyer, hot-wired from EPS foam, covered with HobbyKing film covering. Controls are throttle, nose gear steering, and elevons at the tail (tailerons).

Made from foam board using the planform of the Lockheed SR-71 Blackbird. Did not fly well.

Made from black foam board, wingspan 30 inches, weight 17.3 ounces, KFm3 airfoil. Controls were tailerons on the stabilizer, but were not very effective even at high rates due to being too close to the plane's centerline. Plane was modified for traditional elevator and single aileron.

40th in the So series, made from foam board, wingspan 20 inches, weight 16.0 ounces, KFm3 airfoil. With a stabilizer span equal to the wing span, this plane was similar to So.14. It flew marginally well with some interesting control problems.
