Also, I seem to recall that Skydrive is the UK dealer with a lot of experience in maintaining Rotax engines.
Thanks!


Good link, I didn´t know that forum at all.

Sorry to push back on your nice plans...
No worries………it is a pain though, having to sell this aircraft first.

Nope, it is 2000 hours (TBO) with many passing 3000 on condition.

That is correct, even the new 914UL get a TBO of 2000 from Rotax these days.

This conversion kit seems like a reasonable idea, but they do recommend having a full condition inspection before adding the turbo, and the $8500 is just for the kit, installation/inspection is another $2500 + parts. I guess also the warranty would also just apply to the kit parts.

If you can't sell the 912 I guess it would seem reasonable?
I guess, thinking about it………my Rotax engineer is my friend and he worked my engine from almost zero hours so if I would travel to the States to pick it up, I´d have the whole kit installed locally for a bit more than $10.000,-.
My heart still tells me to stick to the original plan though………..which was sell the plane, and buy a nice, "0 kilometers" conventionally breathing 912ULS.
Granted, my plan is to fly high up in the Andes but talking to owners of both 912ULS and 914UL…………the advantage is on the 912ULS`s side, I´m afraid.

The 914UL consumes 40% more fuel (!!!) and the power difference at sea level is negligible. In the mountains the 914UL wins, but I have seen several club members that make it up to 6000 meters with the 100 HP Rotax 912ULS………..so why wouldn´t I? Obviously, these trips would have to be planned on good weather days…….but the same goes for a 914UL, and as I said; my non-turbo´d friends take off from airstrips at 3.000 meters with their 912ULS.

The extra consumption every day, every flight; the extra maintenance $$…… I don´t know--> I´m torn.

I´m enjoying this thread though………..any more opinions out there?
