Brushless powered slow flyer
Here is my brushless powered 348mm span indoor model.
A motor is made from a part of junk MD drive. Major components like stator coils and a ring magnet remain same as the original but only a drive shaft and the housing are simply modified as shown in the picture.
Motor: DIY 15.5mm out-runner 2.5g 7.5ohm (star)
Receiver: IRXS300&301BM developed by Koichi Tanaka
Battery: 1cell 60mAh Li-Po
Thrust: 6.8g (3.7V, 220mA)
The power unit is obviously not for 3D aerobatics but, as seen in the movie
, it is good enough to drive 11.6g styrene foam plane indoor.
