Scratch built p-51

The wife loves the way p-51s look, and we got TONS of blue-cor lying around. So we want to give a home built a shot.

I figured flying weight around 10oz or less, with elevator and aileron controls with a 24in wingspan or so. Basically, light, cheap and easy to build (and fun to fly )

What kind of powerplant would you folks recommend? We got a spare GWS IPS flying around, but that may not provide enough oomph.

I'm thinking the fuse can be almost 2-d to make life easier, just cut the profile out of 3/4" foam. Then shape the wings accordingly.

Any other thoughts? Gotchas I should worry about?

WHat about the mini BL ac 1215/20 with a MPI gearbox? It would Drill holes in the sky.

At 10oz AUW, the GWS EPS-300 B should work fine. This is the same set up that powers the Switchback and Radical 540. Both around 10oz AUW. Price is usually $18-$20.

I'd suggest a direct drive 280 class motor on 2/3 aa cells

lightest and with the high pitch speed a model like a mustang would like.

have had experience with the GWS mustang with 24 inch span on an IPS s2 and 8X6 , flew fine but the large but slow spinning prop really held back the sleek airframe.

in dives you can practically hear the big prop braking
