We are really getting to extremes here. The thread originally cast around for opinions concerning the -6 as a primary trainer. Those opinions were offered, and the OP has made a decision.
But what is the point of indicating the RV series is so ill suited for a training aircraft that "...it could adversely impact General Aviation and my enjoyment of the hobby..." ? Please take a step back and look at what is being offered here.
Clearly, the -6 is not going to be the "perfect" trainer for some aspiring pilots, but it is a LONG way from the hot rod that some are making it out to be. We all draw from our own experience, and as limited as it is, MY personal experience is that of the 15 or so aircraft types accumulated over 1000 hours in my logbook, the RV is among the easiest. I have never received ?transition training" in any RV that I've flown, and in the case of the -8 and the Rocket, my first time sitting in one was in the front seat as PIC (solo, in the case of the -8). Some will view this statement as reckless, some will view it as boastful, but it is offered only as fact and to provide perspective. Flawed as my opinion may be, I feel that if someone of my limited experience can do it, it simply CAN?T be that difficult. True, not all pilots are the same - If some pilots take longer to get up to speed in their airplane, so be it. But just because some have trouble stepping into an RV, that's no reason to outright condemn the aircraft as a trainer. After all, plenty struggle with the Cherokee and 172 as well.
And BTW, I understand there's a guy here at work who is learning to fly (from scratch) in his -6A.
