The reason why I am asking about a Corvair is simply cost. Rotax 912 engines are getting close to $24K now
, while A completely rebuild 100hp Corvair is under $2.5-6K (about $7k if you have one of the experts build it for you). A Corvair in a highlander drops the completed build price from $55-60K down to under $40K. The weight of a Corvair is equal to or a little less than a o-200. My big question would be building an engine mount and cowling for it. Have any of the builders/prosective builders thought about this?Jon
