na przyklad w eod dalo sie spokojnie zrobic petle helikopterem, w dc zwykle konczy sie to przyziemieniem na wirniku...
ztcw zaden ze smiglowcow w dc nie zrobi petli realu.
to tyle na temat "bogatszego" modelu lotu w eod

hmm a latales w ogole helikopterami w tych modach?
heli z dc nie moga zrobic petli? akurat tak sie sklada ze widzialem AH-64 Apache wykonujace taki manewr na filmie z pokazow, poza tym na jednej z zachodnich grup o lotnictwie czytalem ciekawy tekst, polecam bo to ciekawa rzecz, sorry za wysoki poziom angielskiego ale nie chce mi sie tlumaczyc
"I realize that this is a bit off the group's charter, but as a
helicopter aerodynamicist, I feel duty bound to correct some inaccuracies
I saw in someone's post.
Almost any helicopter can loop or roll. However, to survive the
manouver, don't ever attmept this in a teetering rotor helicopter. They
rely on gravity to provide the control power. In the unloading
experienced in a less than perfect loop or roll, gyroscopic forces will
take over and cause the rotor to precess. Usually, this ends up with
the rotor hub banging against the rotor mast, which usually results in
component failure. Teetering rotor helicopters include the Bell 206
(Jetranger), Bell 204 and 205 (Iroquois/Huey), Bell 209 (Cobra), Bell 212,
Bell 222 and the Robinson R22 and R44. The 222 has something called a hub
spring that does provide some head moment in a low g situation, but I still
wouldn't fool with it. I was once told that only one person has ever
survived looping a Cobra.
Most other helicopters have articulated or rigid hubs, which have
varying degrees of safety in aerobatics. I have seen a video of a CH-53
rolling, a S-55 looping and stills of the S-67 looping and rolling, a
S-76 rolling and a UH-60 rolling. Byron Graham, a Sikorksy test pilot,
is reputed to have rolled every Sikorsky helicopter he ever flew. I have
also seen an incredible video of a Bo 105 doing a complete aerobatic
routine, including manouvers impossible in an aircraft (how about
hammerhead turns, while flying backwards). However, the German pilot who
performed the Bo 105 routine was later killed - flying aerobatics in a
helicopter."
