I had read quite a few articles about the Guimbal Cabri G2 helicopter but I had not ever got close to one.  Then, when we were at Klamath Falls, I regularly saw two of them showing up on FlightRadar24.  Since they were not a focus for the visit, I didn’t think much of it.  However, at the end of one day, we were positioning for the return of a Huey that we knew was out on a flight.  While we were waiting, the two Cabris flew overhead.  One continued on southwards but the other turned to make an approach.  Their base was apparently close to where we were waiting and they taxied right by.  The person in the left seat was clearly feeling the heat as they had opened the door and were dangling their hand out of the gap while the right seater taxied them back to the ramp.
