The HYDII problem is still there, unless I load another plane first with the engine running. After that I can shut down and restart the Draken’s engine with no problem. I went into the aircraft config file and the afterburner threshold was 0. I changed mine to .95 and now the afterburner works fine. (Although the nosewheel sometimes disappears on the runway, but whatever. For what I paid for it, I’m not complaining!) I’ve had the previous version of this for a couple of years, and it’s just nice to have all the effects working! Thank you Thomas for a wonderful model! Wish I knew how to do it!
