Built in a few hours from foamboard with a 20-inch wingspan and length of 30 inches, this plane is a variant of the typical foamboard delta. Powered by a Powerup 400 Zoom swinging an APC 7x5 prop on 3S. Overall weight 13 ounces (318 watts per pound!). Controls are elevons. Flies fast.

Constructed mostly of EPS foam with some foamboard for the stabilizer and fins. Powerup 400 Zoom, swept wings, 17.5 ounces.

All EPS foam except a coroplast elevator. Wingspan 48 inches, weight 61.1 ounces. Tacon 25 swinging a 12x8 prop on 4S. Due to the higher power and heavier weight I used standard-size servos in this one (elevator and single aileron). A great-flying stable scale-up of the famous So series.

EPS foam with foamboard tail booms and tail surfaces. Wingspan 39.5 inches, weight 17.4 ounces. Powerup 400 zoom with a 7x5 prop on 3S1000. Single aileron of course. Will cruise around nicely at 1/3 throttle. Straight up climb at full throttle will make it go out of sight quickly. Flies pretty good as all So planes do as long as they're built straight, strong, and light. This is the first plane I used my FrSky Taranis radio system with, using a D4R-II receiver.

Made from EPS foam and foam board, covered with film. Wingspan 52 inches, weight 29.7 ounces. Features a foam X-15 rocket plane that releases by servo. PowerUp 400 Zoom on the back producing 260 watts.
