Thank you very much for the explanation John. For me right now the biggest disadvantage of the IC engine is that even at idle speed it produce a significant thrust which is not nice when landing. I could kill the engine but then there would be no chance of restart if something goes wrong. With electric I could shut the prop down completely which then pretty much worked as an air brake. Anyway, will give it a go again, thanks for the advice!
