My Posts This: Topic  Forum		Does anyone have any experience with the Kasama Rotorhead on a 90 size heli for F3C type use? Especially with respect to hovering/ handling qualities in the wind. Also in regards to whether the dampening is too stiff at lower rotor RPM. Thanks.

Regards,
Rick

My Posts This: Topic  Forum		We change O'ring by use motocycle soft O'ring. But it short life. Two weeks change one.

Some washer in rotor head kit are not fit. No good for low RPM. I'm modify by sandoff washer for correct thickness.

I akso use O-Ring. My rex hoovers much better. If I do not see the changes during flights, should I exchebge them for new one anyway?

One day it just became your lifestyle.

My Posts This: Topic  Forum		I'm curious about this too as I want to install a Kasama 90 Cyber flybarless head on a 20lb. 800mm AP helicopter. I'm turning 1200 rpm and wonder if the Kasama Cyber head is too stiff.
