I built two similarly-sized Gulfstream II (Daddy Rabbit derivative, I think). Both were powered identically - E-Flite Six-Series 2000Kv (Mega 16/15/4 equivalent) on 3S 2200's, 40A ESC, 7x5 prop, both right about 28oz. Mine was built with fixed gear, my son's with retracts. I still haven't put mine on radar, but we got Ian's on the straight and level at just over 100 MPH with the gear up. Hopefully this winter I'll build another - the kit is sitting on my workbench, waiting in line.

That should be pretty close to what you're looking for with these models.
