Khodges, humble attempt?? Holy cow, that's one heck of a nice plane. I bet adding all that glass area took a bit of time. I'm a hack compared to you guys.
My 1/4 scale Cub has a Saito 150 in the nose which allows it to perform some very unscale like maneuvers (I fly a lot of IMAC stuff), like hovering and knife-edge circles. It's 3 years old now and has given me 100+ trouble-free flights, The darn thing still puts a smile on my face every time I fly it. Here's a rear view shot.

Oh, btw, just got back from the LHS and picked-up these Robart hinges which I'm gonna' try. They're Part # 350 Door Hinge 1/5 & 1/4 Scale, and here's a link to the web page (you mustr scroll down a ways). I'll report back as to how they work.
