I have owned 2 Goldberg and 1 Cermark Pitts (Patrick design) and 1 DP Ultimate-- They are ALL GREAT PLANES--HOWEVER IF IT WERE ME I would wait for the DP-- The difference in the size is worth it! The DP tracks stright on vertical like no other bipe and I have had a few. The tail wires make the neatest sound also--if you are using a 4 strokeyou can hear it. Again for emphisis-you will not go wrong with either, but the fuse and w\s difference on the DP is a lot for me! Just my opinion.
