What would peoples choice of powerplant/fuel be if building a new SEP right now in the 180HP area? Ive just started building an RV8 with an estimated completion date in 5 years. The availibity (and price) of Avgas for the next 30 years to enjoy the thing really worries me, I'm seriously considering looking at electric but the infrastucture isnt here to support it and the extra weight will make it rubbish for aeros...Not to mention the work to get an electric system approved by the LAA...
Is there a Jet A1 option or will that have the same issues as Avgas (espcially at the dwindling number of smaller airports in the UK...)
