Hi Cris Most guys start building there KRs with out positively knowing which engine they will install. Of course the engine should be as light as possible, but it is critical the center of gravity(CG) of the completed plane fall within the parameters set forth in the plans. You can adjust this by building your engine mount to move the engine a longer or shorter distance from the firewall, removing or downsizing the header tank and install wing tanks, and by relocating heavy items like the battery fore or aft. Gotta go, I'm taking off for the KR gathering in an hour. Brant Hollensbe DSM
