I am in the market for a plane and one on my "short list" is the RV-7. I have owned a plane before, so I have a little working knowledge on questions to ask concerning AD's, damage history, corrosion, engine compression, etc.. I understand that a pre-buy inspection by a good A&P is also critical. My question, are there potential problem areas unique to the RV-7 that should be given special attention in the pre-buy or questions specific to the RV-7 asked of the seller? Are there builders of the RV's that know the right questions to ask and things to look for that assist (for pay or gratis) in the process? I flew an RV-6 on a demo flight many years ago and fell in love with it, so when I decided to buy again, the RV-7 was at the top of my list. Buying a used plane under any circumstances gets the anxiety level up, but buying one with "Experimental" written on it pushes the needle a little further over for yours truly, so I'm just looking to cover the bases as best I can. Thanks in advance for your help and advice!
