Notes about the model

Model is of classical balsa design, covered by paper. Used material was selected with respect to weight and strength. During the building I tried to spare every gramm. Weight was the factor in selecting the components for the model, given in the table below:

Receiver: Rex 5 MPD 9g
3x servo: no.8524 19,6x8x19,6 mm 4,3g
Battery: lipo 300mAh/ 7,4V 20g
Motor: dualsky xm2812rtr-27/ 70W 26g

Final weight is 190g. Model is very stable with enough power. It glides nicely when motor is off. I tried stronger and heavier battery 450mAh/7,4 g (30g), that leads to slightly increased power and motor flight time duration, however that does not pay off 10 g weight increase.

The aim was to get slow and nicely flying aircraft in 1/20 scale. The plan is made so the building is as simple as it could. I hope that it can be an inspiration for those who like the original plan.
