Sam,i understand what you are talking about but part of the fun and satisfaction in this hobby is incorporating idea's of your own,not just saving money..designing the plane should be left to people who know what they are dolng,but the engine does leave room to experiment.As you say,i expect i will end up buying most of the parts,i don't have machine shop access.I do have engine experience though,spent my apprenticeship with the De Havilland engine co,the rest of my misspent life with aircraft,industrial,engines,plus R&D on motorcycle production & racing engines..Now retired with lots of time,little money.The 1/2 VW engine seems a prime subject to play with.This is my 4th home build but am getting a bit old to fly,Will see.PS love your vidio's,keep posting them.
