3) Nicer, bigger place to sit in? Could even carry three for self fly hire?
Wouldnt try 3 in a cbi, c no problem
Not so much a case of "wouldn't try it" but more a case of, "it can't be done!"
The 300C is flown from the left seat which means that with dual controls taken out, you can get two passengers alongside (if they don't weigh too much!). However, the CBi is flown from the right seat and with the collective in the middle, three across is no longer an option and there is no third seat.
Hughes500 is spot on - if you're heavier, the R22 is out and, with the R44 being much more expensive, the 300 is an excellent option.
