The side hatch is an interesting idea, and I'll see how well it would work on mine. I am, however, using a rigid carbon fiber pushrod.

I do like the simplicity of your control setup. Going with the pull-pull on the rudder has got the servos scattered all over the compartment, and to get a non-kinked run to the nose wheel, I had to use a separate servo. So, one each for rudder, elevator, nose gear, and throttle.

Cheers,
