Effective Air Speed as KAL-1000 Inputs?

[championofcyrodiil]

Currently I use the "Main Throttle" Action group "input" axis to assign the Prop deploy angle (value) with the KAL-1000.

This works pretty well enough because at higher speeds (more throttle) the blades are angled less (closer to +/-45°) to reduce drag against the headwind, and when at low throttle taking off; they sit around +/-85°.

However, this assumes that my actual airspeed and air density is a fixed constant; and at higher altitudes; >7500M; I end up having to throttle back to 50%; as a 65° deployment angle is more effective at climbing.

If I could use my airspeed as the range; set the domain to something fixed; and assign prop angle based on airspeed; that would be more effective I think.

One way I think this could work; is using "Sensors" typically used to collect 'science data' as inputs instead of action groups.  Perhaps I am way off here, but would be interested in other's opinion.  Keep in mind I am not an aerospace engineer or anything like that.  So go easy on me.

Yes, that would be great! And it probably would allow you to solve your problem.

But I'm not holding my breath for @SQUAD to install it. Unfortunately I don't expect that to be implemented soon.

I ended up mapping my Prop Angle to F/B Thrust (H & N Keys).  Using vessel info in mechjeb, I am able to adjust prop angle (with sensitive bindings by turning on Caps Lock) and monitor the high precision values of the Surface Speed indicator.  Good enough to optimize the prop attack angle and get the most efficient flight based on drag.
