Scout G-CIMX currently showing nearly 54,000' near Great Dunmow - shattering Jean Boulet's 1972 helicopter altitude world record of 41,000' in a Lama; trust the Nimbus doesn't conspire to also break Jean's subsequent and inadvertent record for the highest ever autorotation...
It's doing 500kts as well... ah, back down to 82kts.
