Autopilot servos

[svyolo]

I was wondering if the BH would fly better with a rudder servo than with a aileron servo for roll control. How does the 4 place respond to small rudder inputs?

It doesn't seem that the dynon system has an option for pitch and yaw, at least not yet. They have staffed themselves so short that it seems new feature additions are probably going to be few and far between.

Or maybe Dynon's staff is currently focusing on getting their STCs completed for the certified market? Huge market potential there...

From the homebuilder's perspective, it seems they have probably bitten off more than they can chew at the moment, or maybe I just got spoiled by the higher level of support that predates the current era.

Actually I was asking about using the roll function, but through a yaw servo. If the rudder causes enough proverse roll, you could simply use that for roll control. I just don't know if the BH behaves this way. I don't think I would "fly" the plane that way with the autopilot, ie using heading select to turn. I was just interested in maintaining a heading or course.

Interesting, I hadn't thought of that.

A friend of mine has a Husky on Wipline amphibs. It has an autopilot. I was really curious, because I'd heard bad stories about autopilots in those planes. I flew it a bit and was pleasantly surprised how well it would track and respond to heading changes. It wasn't coupled to the ailerons, but rather a rudder servo, as Matt suggests. Bear in mind, the plane had a couple of big pontoons providing bottom weight and stability. I don't think it would handle turbulence as well as aileron coupling, but in fairly smooth air, I was pleasantly surprised. without the floats, I'm not so sure.

Riding in a 4 place at cruising speed, and approach speed. Push a rudder pedal to displace the nose 15 degrees in yaw. How much proverse roll do you get? The BH doesn't have a lot of dihedral, so maybe not a lot.

My guess, it would wallow around a lot. You could probably make it work, but it wouldn't be ideal.

When does your kit arrive svyolo?

April 1st. I can't wait to start. I am going to start sourcing electrical system parts later this week. Between this forum and VAF, I think I have answered all the questions I had. I appreciate all the help from everybody.

Thank you all.

Hey Matt, what avionics package are you favoring?
