Looks good, I think I am going to make a hatch for the tank too... How did you do you sheeting? This is my first build, and I have yet yo figure out how to sheet the fuse.... did you make a paper template and than cut out the sheeting? And how do you prepare balsa for sheeting, so it will not brake when you bent it around the fuse? As to mounting the hatch, have you considered magnetic strips, or velcro?
Thanks.
