I built one of these a couple of years ago (see: http://forums.rocketshoppe.com/show...ighlight=bumble ) and cut out the parts for 3 more soon after. The Boost Glider thread reminded me to pull them out of the shoebox and get back to building. The instructions (attached) call for the boom to be cut from spruce, but that seemed awfully heavy, so I used hard balsa the first time. This time, I'm using spruce for one of the gliders and hard balsa for the other two. I'm also going to try using tissue on one of them. It's a very easy glider to build and trim (and lose!). I encourage anyone who has never built one thinking gliders are too difficult to try this one. The only change I made other than the spruce boom was to substitute a BT-5 for the pod to use 'T' motors.
