I didn't time my build, but it was in the neighborhood of 16-18 hours, largely because it takes forever for the foam safe CA to dry. I took it out for it's maiden and that's where it gets ugly, partially because I was in a hurry to get it in the air. I have the TP 1320 pack so the CG was way off (even with the battery all the way back). I figured I'd fool around with it and address the CG later. I first took it up and it flew like a champ I was actually amazed at how well it flew (so were the people at the dog park). But I started getting comfortable with it and that's when disaster struck. We all know nose heavy planes like to descend when not under power, well I was doing some low level inverted passes and didn't give it enough down elevator, it headed for the ground, I panicked and dumb thumbed it into the ground nose first. The fuselage isn't that bad, but from the wing forward it's a mess (you know broken pieces of plywood and foam etc..) I immediately ordered another one and figure I can cut some time out building it because I'll be using epoxy more often, I have some CA accelerator now, and all of the soldering is done. I was just wondering how it flies with the correct CG, it has to be great. I can honestly say that was the best flying plane I have ever flown, even if it was only for ten minutes.
