I suggest you dig up the safety stats on experimentals...they are not good when compared to part 23 airplanes (cessna, piper, etc). AOPA publishes the numbers each year.

With that said, I would not set foot in one of those things unless I knew the builder personally and had researched the type. Some types have peculiar issues, others just have bad safety records.

400 hours in the plane is good I suppose.

Are you going to get some advice or hopefully a checkout from an instructor with experience in type? I would definitely not jump in cold turkey and start doing commercial manuevers...
