To anyone that can help.

I have a Sebart WIND 110 with the recommended Hacker motor / esc etc.

The ESC is in default settings incl brake off.

I have been surprised at the lack of down line braking. I have it set to "tick over" at low throttle (rather than stop) but I think the airflow is increasing the rpm in the down lines and therefore failing to control downline speed. This has been a bit of a disappointment because I had expected that motor to hold the rpm that is being requested by my input : not speed up under air flow pressure.

I am hoping that I can alter this with changing the ESC set up but it did not come with instructions ! Although I suspect that this is a wider more general question : are my expectations unreasonable ? Should the motor be able to resist "winding up" on these downlines and just run at the rpm I call for ?
