cruciform tail mixed w/ gyros -- possilbe??

[willshep]

Say you have a cruciform tail.
Both the rudder and elevators (4 surfaces) have elevon mixing. Thus all 4 surfaces "corkscrew" when an aileron input is recieved. Basically you have elevon and rudderon mixing.

Now, could you dampen all 3 axis with gyros? Slip a gyro between the 1st channel before it splits to go to the elevon/rudderons.. and gyros between the 2nd and 4th channel as well to dampen those...
?
I could test it, and will, but just curious if anyone had any thoughts..

thx in advance

Yeah, it'll work, but whuffo?
Such control surface finesse is required for planes which are unstable without aid.
Few models are.

secret skunkworks project.
unsure just how unstable it will be, but considering its flight envelope requirements Ill need the best elec. stabilization i can get (including an FMA copilot).

thanks!

If you're thinking of doing away with ailerons by doing this, you'll get a very docile roll motion. The negative moment of the rising and descending mainplanes would almost overpower the effect of the tail bits. I did something similar with a small Mustang and although it has good stability and flies well, roll is very weak, even after using just about all the stab area as movable bits. Tex.

Yes i have also added corkscrew tailplanes to an aileron plane and found the additional roll rate to be little augmented.

I am not doing away w/ the ailerons.. but will require the elevon/rudderons for a different, ahem, attitude the plane will be in.
