FSX and aerobatics

yeah shame theres no way to emulate the G's, maybe if someone created a vest/suit that constricted to match G's that'd be fun, but lethal lol perhaps limit it to 4-5G (rollercoaster G's) that'd be good :jump: anyways heres a taster of the RJF extra, it's now in Flightsim.coms hands as to it's release time, was hoping for 1700GMT but that looks set to slide...

Matt that looks perfect :)

In FSX or any of the simulators doing aerobatic FDE's takes a lot of care to get the near and post stall dynamics correct, or at least useable. A lot is possible, but many workarounds are also necessary as FS uses a quite simplified set of parameters to model a very complicated set of aerodynamic reactions from a complex 3 D form in varying attitudes. No two aircraft, even if nominally the same type, fly exactly alike.

Correct. FS9 and FSX, or indeed any version of FS, has never modelled independent wings. The main lift parameters are as though for one "slab" of wing and therefore do not strictly model assymetrical lift, one side stalling before the other, one side promoting auto-rotation, etc etc. Microsoft themselves attempted to address this by writing in some pseudo assymetrical parameters mainly aimed at promoting the impression of assymetry of lift, but with mixed success.

In addition, the default params use quite a lot of yaw stability which normally prevents a reasonable degree of side slip of the kind which aerobatic aircraft need for all sorts of manouevres.

The only way to overcome this is to radically tweak these params and juggle them so as to extend the impression of assymetry. It takes a lot of patience and a certain amount of experimentation.

have reinstalled the Avsim.ru Freeware Su-26 and my Repaints that I have done will Release them soon

i agree that certain moves you have to tweak the cfg and .air files to get them to do it, a fair few people said the default extra couldn't knife edge pass due to lack of rudder, oh she can but another key factor is engine horsepower and torque, to do things like tailslides, just make sure you idle your engine, sounds daft but you only power it back 1/2 way into the vertical, example being hammerhead, let speed bleed off till at about 25-30 kts then give it a bootfull of rudder left or right, generally they go left easier than right due to the torque, but by the time you have rudder fully deflected you'll be halfway through the hammerhead parallel top-bottom to the horizon and the 0 airspeed and rudder should whip the tail around and bring you back on plane :jump: seems like my old plan of starting an aerobatics school would be of help to a lot of people who want to fly like that but can never figure it out...

The main difference I have found in real hammerheads and FS ones is in the lack of propwash. The pivot at the top is almost a zero g manuver with the prop blast nicely levering the plane around with rudder. At near zero airspeed the FS planes tend to lack enough rudder power due to lack of prop blast effect.

Yes, a lot of experimentation is necessary! Spinning is possible but a bit trickey to set up. Amazingly enough one of the Corsairs I did would exhibit different aoa's for the right and left wings as exemplified by the angles of the condensation tip vorticies visible in external view.

they just made it available but I think it is the uncorrected version since I gave Matt the HU about a small failure after he uploaded that one

Matt,
just for your information the Royal Jordanian Falcons have flown Extra300S earlier in their history

S variant was in use from 1992-2006 looks like they have changed to L variant during the 2006 Season

question:
have you planned making the rare romanian hawks scheme

Concept 5 RJF coming very soon

maybe I release it together with my Frecce and a totally fictional Paint
as Concept 5 Airshow repaint Package or something like that

Tom check your shine levels pal looks a bit chromed instead of shiny, and yes the Rom Hawks is on my list :kilroy:
