slight dive until 500+kph then level and there you go !
Spin out the comp wheel by over-revving slightly the rpm (this need to fine the prop pitch a little bit more than what you want to let the rpm raise and then get some better boost before reaching an equilibrium)
@Trumps : To shake out a Hurri : pull G : it can't follow or it will depart.
Use your far sup roll-rate at certain speed. The roll rate of the Hurri is poor at most of the speed range.
Pls don't overload your ammo belt with the maritime mine that we've got with that Patch - I guess they borrowed the WM from Silent Hunter
