Buitenzorg. You have my undevided attention! I understand satic rollover as for example, Heli on floor, full right cyclic, up with collective, over she goes. Dynamic rollover, three feet off floor, moving to right, skid hooks in wire, not enough left cyclic to stop movement,over she goes. surely rollover whether static or dynamic is a combination of force in a certain direction resisted by a greater force. I have in mind a pole vaulter who may well lift himself twenty feet using a fourteen foot pole, but would not have sufficient energy to achieve this with a twenty four foot pole
