| The Boeing 40 biplane created by Stuart Natof |
| |
| This plane is based on the 1925 Boeing 40 which won the US Postal Service competition. The Boeing 40 used the Liberty V12 engine left over from WWI, and subsequent models (40A, 40B) used radial engines. Stuart used plans from J.A. Morrow for this plane. The wing loading is 0.98 oz/sq ft with a wingspan of 23.75 inches, and a wing area of 1.27 sq ft. Stuart wanted an indoor flyer that looks like a real airplane with low wing loading for slow flight. The AUW is 34.8 g with a 130 mAh battery. Watch the video for realistic takeoffs and landings. |

| The Boeing 40 has a MINOR receiver, MCF5030S carbon fiber prop, two MCS2 coil servos from MicroInvent, and a Gasparin GB45S7R motor. The plane is covered with aluminized 2 micron mylar, and the fuse is 1/64th inch contest grade balsa. |
