Dave,
My Edge airframe should be here soon and the build will start, YS 140 sport for power. We talked before about a 17X8 or 18X6 APC. I'm finding out that the 17X8 is not a problem although there is a difference the pattern and N blade. The 18X6 has been replaced by a 18X6 wideblade. There is also apparently a difference between the pattern and sport propellers if you can find them. Would using the wideblade in this scenario IMAC and Precision aerobatics be a problem? Special spinner cuts will be neccesary, so your advice would be appreciated.

I would appreciate your advice on the fuel tank plumbing, would you recommend large or medium sized fuel fittings and lines for the 140. Thanks...
