That would be a very nice setup indeed. That would get you over 50mph with only a few minutes of run time.
I don't think the empty hull would weigh 5 pounds, especially for a 0.18 cu in engine. SHould be much less than half of that. This hull sounds like a AQ Miss Vegas? Do you wish to improve on stock speeds or keep roughly the same?
