RE: A 4H controlline trainer
John, your "bash" looks great! I especially like the idea of the ailerons still being adjustable, neat idea. Being that the plane has a rather long tail-end, it should make a GREAT CL trainer.
I asked my granddaughter about the 4H aeronautics thing and she told me there's a whole program there, aimed primarily at stuff like crop-dusting but apparently there's no "top end" and the kids can go pretty much as far as they want into it. I like that!
Should any of the kids decide they want to go further into this and actually try building/learning what it's all about, I might suggest the SIGAkrobat - another great CL plane in the .15 engine range. I taught my daughter to fly CL on one of these and she had no troubles at all. Once she was comfy with the control rod all the way down at the bottom of the elevator horn I started moving it in - she now flies CL as well as I do (maybe better - she doesn't have to pay for repairs, I do) and has moved in on my Skylarks & Shark-45.
