RE: Extreme Flight 88
Glad to hear you are enjoying the Yak Barry. I 've had similar issues with the pipe slipping out of the Teflon coupler. One solution is to drill a small hole through the coupler and pipe and tap it for a 4-40 bolt. Put a washer on a short 4-40 bolt that is just long enough to get through the thickness of the coupler and pipe wall and insert it with a couple drops of red loctite. This has worked well for me.
