Nick says:
" The climb limitation for most helos is generally due to the somewhat silly handling requirements of FAR, where the longitudinal stick stability is measured at max climb rate. Some helos have difficulties meeting it, so they impose a climb rate limit at the highest climb rate where the handling is still compliant "
yes, that is why the 407 is limited to 2000 fpm VSI, and you do have to watch it as you can easily hit the 2000 fpm in that rocket
