Hi everyone. Been lurking a while... Peat this point I decided I will attempt to build a STOL from a commercial kit. Something like a Highlander or Zenith or similar. I'm most interested in short takeoffs and landings... The ability to land on a postage stamp is terribly exciting to me. As long as I can take off from said postage stamp, that is Now I'm trying to understand engines better. I only have bookworm knowledge so far, and would like to get better at evaluating engine options. What kinds of tried and true options are out there? I understand it's not enough info so I will attempt to narrow it down, even through I'm not 100% sure why. Air cooled direct drive 100 hp or thereabouts lightweight 4 stroke TBO should not be too low Straightforward to understand engineering. I don't want to have to go to a mechanic for everything cheap Rotax is all well and good, but ouch my wallet... Jabiru is apparently rather heavy ULpower also interesting, but a bit pricey for me. Honda looks interesting but also not super heap, or is it? The auto engines are. Lots of old postings on this forum with links to defunct websites... I would be thrilled to hear some people here point to solid engines that can be used for the purpose without breaking the bank. And if it has to be a rotax 582 I guess I'll have to get comfortable dealing with gearboxes I suppose... Thanksmfor any pointers.
