Hi RV9flyer,
Ditto...you get the pioneers and you get the conservatism, I'm the latter.
Sorry but I do not have much info on the exact causes, the last time I saw the guy and his plane I asked him what happened to the BMW since it was not fitted anymore, His response short and sweet: "After 3 engine outs I decided to go Rotax". He was annoyed with his failure and not really interested to talk about it.
My main aim was to tell you that if you go with intended you go with a minimalistic knowledge base where as with a Rotax it is much better understood in general.
For some people is all about the money, the other about the challenge and satisfaction of success of making something different work, for others it is about piece of mind, tried and tested by many.
This is one of those never ending debates, but please keep us posted on your findings.
Kind Regards
Rudi
[font="]PS: I followed the link you provided and see they advertise it with "[/font]CENTRIFUGAL CLUTCH"[font="]. This reminded me of one of his gripes while flying the BMW it was that one have to anticipate the clutch kicking in or not. Especially during tricky landings when one is required to play with the power setting, and during simulated engine outs. This creates and additional workload during tricky landings and something to keep in the foremost of you mind. I do not know if your option would include this or not.[/font]
