Any of you guys done any teaching in experimental aircraft before? I have a potential student looking to finish up his commercial in his own experimental aircraft. I asked him to bring in the a/c logbooks to determine airworthiness etc. Anybody know of things I should look for before I even get in the aircraft with him?

He has stated he has about 400hrs in the aircraft and all other CSEL requirements met, but I'm definetly checking his logbook for that stuff too.
