Rangerman.............I've used the Robarts incidence meter, a matter of fact I use two of them to check incidences. Harry Higley has a book on Bipes excellent source for the Ultimate. You are on the right track, the wings, thrust line and horizontal stab incidences most important, just be patient . I am not familiar with the GP meter. Somebody recommended to me the Harry Higley book and I just went for it, plus a friend of mine uses the Robarts meters.
My Ultimate is the ARF, still I'm going to check it for any warping.

AirborneSGT........ if you are flying a 29% Ultimate that is a 3D great machine, you'll probably won't like the smaller Ultimates. I'm not in there. What's great about the smaller Ultimates is that they are fun to fly with less transporting hussle. Especially if you're a busy person and don't have that much time on hand. I chose the CG Ultimate 10-300 ARF from recommendations (everybody has his own reasons, can't argue that) I did some research and compared with DP. Cermark used to handle the DP. DP decided to sell them directly about one yr. ago, their size .40 was going on the market beginning of 2005. When I called DP I was told to wait till about March of 2005. I did'nt wait so Santa got me the CG Ultimate 2004. The CG Ultimate was designed by DP. The CG is a .60.
Cannot tell you which one will fly better, in your case you'll most probably like them both. If you're flying 3D you can tweek them both to your taste. Good luck with your choice.
