Default RE: Extreme Flight 87" Yak 54 - Build & Fly

I believe Drew is referring to the flex header. You must wrap the flexible portion of the header with teflon plumbers tape or you will have a huge mess on your hands. After a few flights the tape can be removed as the exhaust residue clogs up any leaks. I too spent quite a while cleaning out the inside of one of my planes before calling DA for a solution.

Drew, the Dubro part number is 553. It is 5/32 silicone tubing.
