Here in South Florida A/C is something of a "must have" and where it is true the R22's here have no A/C, those that can offer a training platform which does could stand to gain the lions share of the training market.
IMHO if Guimbal wants to break into the US training/personal market in a big way they will have to accept the US reality.....American's like comfort and convenience and in most cases are willing to pay a premium for it as well.
It would also benefit the bottom line if Guimbal were to offer fixed floats, again opening a door to be more competitive against it's primary competition the Robinson's.
Perhaps Bruno isn't interested in competing head to head with Robinson, I cannot say. What I can say is, currently the market is dominated by Robinson, one is served well to see what the competition offers if one wishes to be truly competitive and therefore achieve a higher level of success.
