This time I'm back to basic by using all foam board material with some plywood parts. This De Havilland Tigermoth biplane RC plane is designed to have the same scale as PT-17 Stearman. While Stearman wingspan is 1300mm this Tigermoth wingspan is 1200mm. Smaller but still can do short take off. Using 3536 1200kv brushless motor, 40A Esc and 3S 2200mah can give this plane more than 5 minutes of flight time. The flying weight is about 1145 gram, with that made this model has 4 on wing cube loading and that's almost like a glider. Because it's the same scale as Stearman you can use Stearman's papermodel pilot figure.

Specs :
1. Wingspan 1200mm / 47.2 inch
2. Flying weight : 1145 grams/ 40.4 oz
3. Wing loading : 26.2 gram/dm2 - 8.6 oz/sq.ft.
4. Wing cube loading : 4 (Between glider and trainer)
5. Wing Area : 43.68 dm2 / 677 sq.in.
6. CG : The rear center wing strut on the upper wing.
