After weeks, and I mean weeks, of playing with 3d max and FLY2 and all the tutorials, I've succeeded in "figuring out" how to animate the ailerons. One of the best tutorials sites, which explains modeling in 3d max and particularily the type that affects FLY2,is Battlefield 1942 tutorial at http://www.inicia.es/de/lorenmarti/tutorials_01.htmThis is just a fantasctic site for speeding things up.tony

G'day Tony,Thanks for the link. It takes a slightly different tack on modeling to the tutorial I'm following . It appears that in 3d modeling there is more than one way to skin a cat. :-lolThe section on aileron animation looks really good.Thanks again,Cheers,Roger @YSSY
