Скачать или смотреть Homemade Coaxial Helicopter cyclic Roll testing

This test was to check the free cyclic movement of roll under load.

I have changed the gearing from 5.6:1 to 7:1 this has set the tip speed to 530ft/sec at an engine rpm of 5040. I'm happy with the ratio and speed of the rotor now but I believe the engine is not producing full power due to the exhaust not being tuned. This is my next task.

I thought changing the gearing would have improved lift from the last test but I'm disappointed to find it hasn't.

I haven't tried more pitch than 4.5 degrees on this ratio yet and I will try this just to see if an improvement in lift is possible.

The weight of the craft is currently 118kg and the expected max take off weight with 60hp is 275kg.
