Matt . The bull pup D12 is a sports scale rocket. I had one that I flew often and lost it on a roof. With the 2010 challenge asking for a duel review, I dusted off two kits from the build pile.

Of course I know it's just ...

Construction The first thing I noticed was that this model was in a box. Some Estes kits are in flimsy plastic bags, which makes the parts prone to creases and such. I opened up the box, and all the parts were ...
