I am looking to build my first plane. I really want a 2 seater touring type aircraft so the RV14 or 14A came to mind. However i live in europe and dont want to pay the huge prices here for 100LL that comes with a Lycoming engine.
I see though that ULpower are about to release their new 520 220HP Turbo engine. It struck me this could be a good replacement for the IO-390-EXP 215HP engine as it burns mogas up to 15% ethanol. Especially as the 520 is likely to have most of the power available upto height.
However one issue i see is the effect on CG. the 520 is about 30 kgs lighter than the lycoming, do more experience builders think this would be an issue? I may have to go for a europa elite + or Whisper 350 gen 2 if cant get a mogas power plant in the RV.
