Thanks shytorque,
don't foget I am a gyro fan, is just try to point out what are the "myths" and "impressions" commonly spread in the whole air-people.
I finally came to the same conclusion as you... 2/3 extra cost for 1/3 extra capabilities are not justified in most of the cases , except for some SAR ops, mil ops, sling works or so.
I think also that the most of the light gyros suffer an obsolete design (i dont talk about groen, or carter), reviewing the gyros design ina modern way should be of interest, that's what i try to do at my humble level.
Thanks
