Re: Thrust control law for improved vertical stability and h

I've found it helpful to set the thrust at about 35 and 75, which gives you much greater control over the amount of trust. I can actually hover in place pretty reliably. I am sure there are more ideal numbers. Thank you for your hint on the thrust range. I just have flight-tested it with the origin...

Re: Thrust control law for improved vertical stability and h

The "trigger to lock thrust" looks a good idea. From a certain point of view it is a kind of "thrust trim" (another possible implementation could be 2 shoulder buttons -trim up and down-). But yet I am not sure that it solves my initial concern. Let me call TFH to the "thrus...

Here is my solution so far: http://pastebin.com/4U8TJv6b (only the most relevant lines) I have chosen a linear law instead of a polynomial (or exponential) one because humans are more co...

Thrust control law for improved vertical stability and hover

My ability with my PS3-like controller is quite poor (I admit not being a gamer). The analog controls are dreadful: the dead band around neutral is way too large, the controls saturate half way up to the maximum (or minimum) and the effective range for controlling the thrust is tiny. On top of that,...
