Moving the spar to the rear sounds good. A strong tie in with the wing tip framing and L.E. and T.E. should work.
Is the engine eating plugs? If not, I agree that there is still power to be found......[)]
I was thinking the same thing about the spar, the only bummer is it wount build in my fixture [:@]
You're right.
I only ran it long enough to warm and tach two quick tests and the only adjustment was to start rich and lean out, so the plug life is not yet known.
A too short header may blow them. I will try 1/2" spacer if needed(the pipe was slipping back and it was gaining speed). A bit more ground test and some air time (barring any foaming) will give me plug life info. Plug are a major issue with the price of rare metals going up and harm to the engine.
