Russ, aside from the actual 3D flying ability discussion I say go with the Ultimate. Why - the "This is just plan awesome factor" of the Bipe. I have a H9 Cap232 with the Saito 180 and a Goldberg Ultimate. I have hardly flown the Cap since I got the Ultimate. It is just a blast to fly and people love watching it. The only other factor here is the time factor. You have to put together and take apart you bipe and this takes three times as long as a single wing.
