When it comes to the Rotax, there are a lot of people who swear by them. There are also a lot of people who swear at them.
The bulk of Rotax designs are unsuited for IFR or even night VFR flying, by Rotax's own admission. They are lacking some necessary equipment (I forget what it is
). However, the Tecnam Bravo and Super Echo are good looking airplanes, and I think the quality is there. I even like their low wing Sierra.
One other thing, a friend told me that Rotax does not allow the rebuilding of their engines. You have to buy a replacement and they scrap the old one.
