The R22, would be a much better and possibly a safer machine if it was possible to have more energy ability in the rotor/head, and the possibility of slightly more space inside the cabin, fit a nice romote type of cyclic, better seat belts and a slightly more modern instrument panel, larger dia tail rotor shaft, beefed up main and tail gearboxes, more power, a better set of skids and then I think the R22 would then be fit for some serious enjoyment, Oh, and a compartment for the odd suitcase, but then would this be called the R22!
