Steve, after having my Goldberg Ultimate for two months now and about 20 flights. I would suggest you take a serious look at it if you are looking for a new Bipe. It's basically the same plane, but in a size between the DP40 and DP120. In the last few years I have built about every kind of plane you can think of and the CG ultimate is as good as it gets. On top of that they include a complete parts list and one call gets you service.
