Is there any point in converting a three-channel rudder-elevator-throttle plane into an aileron-elevator-throttle plane? The plane in question is a Herr Mini-Sport. I was pondering the kit-bash required to make it 4-channel, but wondered how well it might work with just aileron control instead of rudder. Along the same vein, do you ever put a steerable tail-wheel linked to the ailerons on a fixed-rudder plane?

P.S. If this is the wrong forum for this post, please feel free to move it as appropriate (1/2A or park flyer? wasn't sure exactly where it belonged)
