Hi Bill,

Thanks for taking.

I'm currently using a mouse with a saitek throttle and so haven't ran into
this issue.

I'll have to give it some thought to how to create a trim cyclic for
joystick users, if the workload is considered onerous over a long flight.

I chose to use a turbine and prop combination, which I'm really happy with.

I'm happy with the flight characteristics after adapting it to have a
stabilizing rotation around the lift point.


Regards

Simon.
