For my trial lesson in an S300C (LHS P1), I sat on the right hand side so my instructor could start the engine - after that, all training I did was from the left seat.
Now flying a right hand seat CBi and I had very little difficulty in changing across
except for pushing in the mixture control on start; that's a bit awkward!!
The CBi doesn't have as much power as a C, I wonder how three-up in a CBi would fare???
