My question regards the springs that hold the various exhaust system parts together that came with the Rans kit; they are bronze color and are 2 7/16=94 long and very stout. It took myself and another grown man to pull the springs open enough to capture the welded loops on the pipe. With the used 912ULS I purchased came a silver spring 2 =BC=94 long that has much less tension when pulled open; I can connect exhaust parts by myself. So my specific question is what are these two springs? I would like to order more of the silver version (I only have eight and need four more) but don=92t know what to specify or where to get them.

Pull and the spring opens easily with no danger of busting your knuckles. I tired that method and it works great. Not my idea, but another pilot's good suggestion. ----- Original Message ----- From: Bill To: rotaxengines-list@matronics.com Sent: Wednesday, March 06, 2013 7:53 AM Subject: RotaxEngines-List: Exhaust System tension springs Hello, I am building a Rans S7 and now installing the 912ULS engine.

Grab the spring and use both hands and lean into it and use your weight instead of your wrist and forearm. The springs from CPS (original Rotax springs) are less stout than a few aircraft MFG's. They are easier to install and work just fine. Don't forget to safety wire them and applie high temp silicone as per Rotax. -------- Roger Lee Tucson, Az.
