Before you go cutting things up you need to slow down understand some points about flying conventional RC aircraft with two axis controls so you can make your own decisions. Hard to follow but it sure sounds like you were listening to folks who have no idea and are speculating. Have you actually flown it yet and find your conclustions to be fact?


Fisrt I want to make it clear there is nothing wrong with flying conventional sized glow trainers on two axis it can work fine and in some cases quite fun.


I am only going to address the so called self righting issue and the 'sportiness' of the handling issues. OK here goes:

For an airplane only using rudder for directional control to increase control response (sportiness)you increase dihedral to make it easier to fly and to slow the response you reduce the dihedral. A totally flat wing without ailerons cannot be controlled. All of this is opposite of what would apply with an airplane using ailerons.

Now how that applies to the so called self righting tendency: The self righting tendency will increase if you increase the dihedral and the tendency will be less if you reduce the dihedral

These two simple facts never change and will always apply. Now I know it seems odd that increasing the dihedral will increase the righting tendency and increase the sportiness (control response) but if you think about it thats a good thing and the go hand in hand. If you want to maintain much of the righting tendency but reduce control response you reduce the rudder throw or size.

I am not sure what the plans are suggesting for your two axis setup but I would be far more inclined to beleve them than listen to a bunch of heresay.
