We use the OA-10's for forward observers. It takes some doing, but we have now managed to be able to place the fire anywhere we want, it will react to real world weather which is available in the flight sim. And yes thats Captain Sims model, I love it. The smoke jumpers I found on a site, someone else did them but it works great, you get too low and you don't see no chutes, lol. I am trying to convert my favorite, the B-17, into a fire plane now, they were actually used up in Canada for years. Thanks for the interest.
