Probably the best way to determine the split within the gyroplane community would be to read the gyro forum in the USA.
www.rotaryforum.com/index.php
It will not take long to understand that even though there are many gyroplane kit manufacturers there is more bitterness and outright venom created in the RAF discussions than all other machines combined, in fact there is no other real problem except the arguments between the pro RAF and anti RAF factions.
One of the most interesting methods that the pro RAF group use to discredit the anti RAF group is to lable them as "Bashers" which is the American PC method to silence anyone who disagrees with group think with no other method to argue the point. "Basher" is the gyroplane equivilant of "Racist", "Homophopic" , "Bigot" etc. You just have to wonder if the gyroplane community will ever evolve and join the rest of aviation and accept physics and aerodynamics the same as the rest of aviation.
If you are into the soap opera kind of entertainment with an aviation flavour read the ongoing circus on that forum and it will not take long to identify the actors in the play...enjoy..
