Then there is the cost of the engine. Since no STC exists Continental will not let you exchange a c-85, c-90 or O-200 for a core charge. And in case you are wondering, a certified io-240 runs just under $50k US from Conti

However, a remanufactured non certified with all new internals can be had for 25k new from them. Problem is, putting a non certified engine in means she will never be certified again which means you must stay in the Experimental Exhibition category. But, this does free you up a lot to do what you want going forward...
So my question is this: Does anyone here own or know somebody that owns an experimental exhibition? You read all sorts of things online. Some people saying it is so restrictive it isn't even worth considering and other people saying you just fly it like a normal plane and if anyone asks you are keeping flight proficiency which is technically never a lie...
