Hi all, I really need your help please. I am a member of the Aeroworx team that released the Aeroworx C-47 / DC3, and now in the beginning of this year the Tiger Moth. I am trying to give the Tiger an engine start flame and a bit of smoke. It works perfectly in the Particle System Browser with the Preview but for the life of me can't I get the correct data ref to use so that it actually works in X-Plane. My email address is frederickstegmann@aeroworx.co.za and your assistance in this matter would be GREATLY appreciated; I will give you all the necessary credit in the next update of the aircraft... Both our aircraft are available on the X-Plane forum as freeware. We are working on a major update for the C-47. Thank you and kind regards!
