F1D blog 1

Actually, I’ve played indoor free flight model for 6 months. I’ve already made some achievements during this period of time. For the last several months, I have concentrated on one special model and studying relative knowledge (know how) such as some aerodynamic analysis and construction things.

For example, this model.

Recently, I designed a new indoor model, in accord with the ASFC (Aero Sport Federation of China ) F1D-P rule, wing span 300mm, length of the model 450mm. I use two combined 2*2 rather than balsa tube, because my technique is still immature, balsa tube is even heavier than wood sticks. I’ve made 2 versions for it.

The first: 1350mg

Version 2: Relatively less stronger, but 1035mg, a huge mistake was made that the motor stick is too heavy and weak.

The flight video will post in April.

Thanks to one of my coaches Mr. Zhang Qiang, I have a stadium to fly my model.
