my apologies, i made a mistake when i said to edit the aircraft cfg. under [EFFECTS]!!!
first it appears the air file the plane you are using has to have the afterburner configured in the air file .(it apears your afterburner works)
2nd sometimes you place the files or it may be the subfolder that you place into effects in your main flight sim. double check the authors read me instructions.
3rd you are to add the effects under [LIGHTS], use the next number and add the effect ; example as on the f16 viper that uses the toronado reheat
this plane had a subfolder and a file moved into effects and used both for the reheat.
[LIGHTS]
light.17=6, -19.2, 0.0, 4.0, fx_afaburner
light.18=6, -22.2, 0.0, 0.37, efall.fx
-19.2 would be yer contact point(lenght), in this case it is -19.2 behind the 0(zero)point on the plane .
0.0 is the (lateral) point, in this case right about dead center of aircraft.
4.0 is the (vertical) position, in this case slightly above the zero contact point.
the zero point of the aircraft is usually determined by how the author placed the 3 view drawings into G-max or design studio; sometimes its by default, sometimes they did mip it at about quarter chord(.25 percent back of the main wings)
type is critical when typing this in aircraft cfg. for it to work.
there used to be a assignment key under joystick in msflight sim. for afterburners.
some do engage by just simply at full throttle or the author of the plane, assigned a special key command.
hope you see your reheat; we did it different on early boeng 707 and douglas dc8's to imitate water ethynal boost. happy flying-AXE
