question

Hello, did you assign your Throttle for both engines ?

The elevators aren t far enough from aerocenter in Flightmodel.cfg, so the aircraft falls from the noze.

After restarting the sim, the plane works correctly.

I don't know a lot about flight models, but I'll just list some observations:

• It accelerates really fast. When I put full throttle on takeoff it blasts right through flap/gear retraction speed.
• Stall speed is high. The plane will stall at 145kts flaps up and 120kts flaps down.
• For some reason elevator control is less at full stick backwards than at 80% backwards. Maybe something to do with the front fins? It will also slow the plane down a lot.
• The landing gear absorbs too much energy. I can slam the plane into the pavement and it won't even bounce.

Thanks a lot for this feedback MrLiam, I think you do know more things than me about flgith models :)

You can play with the table n1_and_mach_on_thrust_table in engines.cfg.

Also with this line:

afterburner_on_thrust_table= 0.0000:2, 0.5000:2, 1.0000:1.2, 1.5000:2

But this line disappears of the engine.cfg file when doing a Save&Resynch.

So we have to edit it independantly and only do a Resync without Saving.

I know it stalls at high speed, i know that a Delta wing is complicated to emulate, but i also know that in real life, Delta wings seem to behave this way without Canards and without electrical control ?

I tried to set Flybywire at 1, the behaviour is better at low speed but after Mach1, the elevators don t react anymore...

I will try to update the contents of the model via Onedrive, and anyone can try to modify parameters, putting the files in MouseAircraft in the SDK.

I realize that adjusting exactly the wings to this model makes it hard to control.

I need to cheat a bit: setting the aerocenter around -4 or -3 and shortening the root chord to 30. This way it s really easier to control at low speed.

So the distance between aerocenter and elevators matter when flybywire=0.

I`m expermenting this table:

afterburner_on_thrust_table= 0.0000:2.0000, 0.5000:3.0, 1.2000:4.0000, 1.5000:5.0

With these values i can reach Mach 4 !!

Before i was using this table to increase Max Speed:

drag_coef_zero_lift_mach_tab

I would like to know the inifluence of this last table because now with afterburner_on_thrust_table, i can increase speed.

Does it still have a big influence ?

A little update.

Landing gear animation`s lenght=400.

Respected original drag_coef_zero_lift_mach_tab .

Only playing with afterburner_on_thrust_table .

So, weight repartition seems to be crucial.

CG and Fuel Tank position modified.
