Eje! eso no es asi amigo mio

, con exepcion de las ruedas ,rudder ,y los motores (prop) Todo lo demas tags deberas animarlo tu mismo ..
Wow! that doesn't work like that buddy! with the exceptions of the tires rudder and prop all the rest of the tags you have to animate it yourself el comando f_canopy funciona mediante la animacion que tu creas ,por ejemplo ANIMATE frame0 (la compuerta cerrada) Frame100 mueves la compuerta con el ANIMATE activado y la colocas en su posision Abierta , Luegos Mueves el frame slider Y vez la animacion que TU hiciste ...
Ejemplo
aunque este avion no es para makemdl9 sino para modeldef.xml (FSX)
Le cambie algunas cosas para que veas
the Tag f_canopy works as the animation you made it to it, for example ANIMATE frame 0 (Closed door) Frame100 you moves the door and set it in an open position ,then move the slider and see your animation..
EXAMPLE:
eventhough this plane I'm not making this plane for FS9, its for modeldef.xml(FSX) I change few things only for you to see it as an example
a todas estas animaciones que vallas creando Sin Exepcion (Fijate en la primera imagen que te puse arriba) deberas "APPLY TO PIVOT ONLY /RESET SCALE " porque si no te dara problemas al exportar a mdlall these animation you are creating within exceptions (Take a look my first shot I post for you above) You should "APPLY TO PIVOT ONLY /RESET SCALE " , otherwise you would have problem at the time you export
