First I have the best 3D ultimate for a 50cc engine which is my Wild Hare Ultimate. I am wanting a basher for a smaller bipe.

How much better is the DP Ultimate over the Goldberg Ultimate? I have owned the smaller DP Bipes and they flew very nice. Regarding the gear to put in the basher it would be:

Digital Metal Geared Hitecs or JR
Lion RX pack
Most powerful engine not to upset wing loading

I know the Goldberg Ultimate was one of Dave's earlier designs. The only thing I like about the DP Ultimate is that it is IMAA legal from the start. Since this is just a basher and I have a bunch of big planes already this is not so important.

Any feedback from people who have owned either would be appreciated.

Oh yeah for owners of both, what engines do you use to have enough to hover and such.
