Hi Bill, Jeff,that's a beautiful job.... I have a question, the answer to which might enhance your story - since you have a generator attached, if it's 1/8 scale it ought to be able to produce 17/8 = 2.125 KW, but of course power doesn't scale linearly - can you increase the load on the generator and (since you have a volt meter and an amp meter) tell how much power your engine puts out?

As a "werrit" (someone who worries about things even for no reason, and who sticks his nose in where not appropriate...) I spotted your remark about non-linearity of models: Of course, when it comes to things like polar moment of inertia (4th power) Stiffness of beams (3rd power) volumetric considerations (engine displacement etc. Cube = 3rd power) Areas (area of piston = force developed on con-rod) etc. I understand all these matters, but for a generator I would have simply guessed at a volumetric (cube, 3rd power) relationship with scale? I.E. for the "same" flux density as the full sized generator, and speed of change (dB/dt = rate of change of flux: or N=>S =>N at the same rpm as full sized) then the "Power" developed in a generator could be purely a volumetric ratio, of the "volume of flux" involved? - or "Volume of copper wire" involved? I haven't thought too deeply about this, but maybe you have the answer and explanation? Hence 1/8th scale generator = 1/512th of the power? => 17kW => 33w?

Thanks,
