Test flying home-made rotor blades.

This is the 12th test flight with these rotor blades. I milled them from oak. The blades are 580 mm long with a chord of 42 mm. They are semi symmetrical and have 3° of twist. they weigh 67 g each. I am developing blades for a scale helicopter project.

Hovering takes 318 W. It would probably be much more efficient if I had just bothered changing the gear ratio. I flew for 15,5 minutes and used 2250 mah.

The helicopter is a Century Swift 16 which has been stretched with Swift 620 parts. It has a Hacker outrunner and 8S 4270 mAh lipos.

1100 headspeed? Wow. So you were doing 150 mah per minute!
