| T77, 7 Wing Plane designed by Stuart Natof |
| |
| |
| The 'T' stands for "Triumph"... of engineering over common sense. |
| |
Stuart says the chord is 3 inches, the wingspan 24", and the vertical space between the wings is 2".
That makes for 3.5 sq ft of wing area, from a 1 ft by 2 ft frontal. The all up weight is 46g with a 130 mAh battery, providing a wing loading of 0.47 ounce/sq ft. The dihedral is 8 degrees (on each side); I should have made it 11 degrees. The tips are fenced to avoid crabbing. |
| The power plant is a Gasparin Potensky 4 watt brushless Bee with a MicroInvent (MI) 5030S prop that provides plenty of power. The receiver is a MI MINOR, and the speed controller is the MI MBC2. The T77 uses a MI MCS2 coil servo for the elevator, and the larger MCS3 coil servo for the rudder. |
| The cover is 2.2 g/m2 clear mylar. The leading and trailing edges are 0.028 OD CF tubing (from Peck-Polymers) as are the assembly verticals. The 24 mm spoked wheels are from MicroInvent and they weigh 0.25g each. |

| Truly a triumph in engineering Stuart. |
