SO....when it comes to engines for the Kitfox it looks like you have a few choices:
1. Rotax 914 $30+K (115HP)
2. Lycoming 233,235 $25-30+K (115HP)
3. Rotex radial $25k (not in the scope of this debate) (110HP)
3. Rotax 912 $19k (100HP)
4. Viking $14k (110HP)
5. Corvair $6k (110HP)
There are a few others like Jabiru, but you get my point.
We all know the 912 is the gold standard and would be the easiest over all to install. And most important it is supported by the manufacturer. Logic would tell me that is route to take.
The problem I have is with #5 because cost definately is a factor. I have never built an airplane before and have no experience owning or maintaining one. I damn sure dont want to trip over a few dollars and fall from the sky in a torrent of hell fire because I was "cheap" either. However, from what I have been reading (and I can only go off the info that I have found so far) the Corvair engine can be made extremely reliable, and is a HIGHLY cost effective power plant.
The benefits to me are:
1.Cost- its affordable
2. I can source my own engine
4. parts availablity
5. this is something I can tinker with and build myself. (-After all this is why we are doing this correct?)
Cons:
1. difficulty installing, engine management, cowling,ect
2. Needs carb heat to prevent icing.
3. not supported by manufacturer.
4. Engine is older than me.
5. What I dont know may kill me...
I know of one Corvair proponent on this site (and thank you John) but before I start throwing money around (even if its only a $100 for a Core, or $50 for a book) I would to hear the thoughts of others and glean as much information as possible.
Thank you in advance.
