The CB/CBi is RIGHT seat pic. Some history..The CB was born out of discussions in the early 90's with Schweizer when the NTSB was threatening to ground the Robinson. The idea was to bring the cost of acquisition and operating costs of the 300C, closer to that of the R-22. A number of "downgrades" were made to the existing 300C model. One of those was to take away the capability of carrying 3 people.
The "B" in CB stands for "basic", as in no capability to put in a third seat--which is why the PIC sits on the left in the C model.
