I have listened to some of the new sounds that people have done for the 29. They sound good, but if anyone wanted to make them better, I found two clips that are great. They are on
www.audiomicro.com. They have the start up and in flight. Sounds like it was made as it was passing over head so maybe if you cut it you can get a good loop out of it. The clips cost money to DL. If nobody is willing to pay, I could get them if someone wants to make them work.
