Cut off the corner (about half) on a 45 degree (on the outside). Then, turn down the end like a lip. Tie the baffles up tight. All of them. The straps on #1 and #2 do not need to be cut back. ________________________________ Message 3 _____________________________________ Time: 12:58:58 AM PST US From: TeamGrumman@AOL.COM Subject: Re: TeamGrumman-List: Baffle cutting --> TeamGrumman-List message posted by: TeamGrumman@aol.com In a message dated 5/2/06 9:40:38 PM, gilalex@earthlink.net writes: > It replaced the twisted wire I previously had - and the parts manual even > shows springs..... > Springs are OK if you put a 'pop' rivet in the baffle (with the head on the inside), then punch out the mandrel,then hammer down the tail. If you really smash it, drill it out with somethin in the 0.060 range. Otherwise, the constant load on the spring will pull through the aluminum baffle. I like the twisted Safety wire trick. ________________________________ Message 4 _____________________________________ Time: 01:01:31 AM PST US From: TeamGrumman@AOL.COM Subject: TeamGrumman-List: Horizontal --> TeamGrumman-List message posted by: TeamGrumman@aol.com Does anyone have a really nice horizontal for sale? Or know of one? I have a very good serviceable one to trade. ________________________________ Message 5 _____________________________________ Time: 05:34:11 AM PST US From: "flyv35b" Subject: Re: TeamGrumman-List: Baffle cutting --> TeamGrumman-List message posted by: "flyv35b" The safety wire will also pull through the baffle hole in time. 2 holes drilled about 1/4" apart and threading the wire through both of them will help. A rivet also works good with safety wire and you can even put a cotter key through the hole, bend the ears and put the wire through the cotter key.

Static RPM increased 125 RPM, with a similar increase takeoff/climb RPM. There is a very marked difference in takeoff acceleration and climb performance. Engine is at TBO. Since cruise RPM did not change, no noted difference in cruise performance at this point - we don't have fuel flow instrumentation. The system is very well made and designed, looks good, and was fairly straightforward to install. The price is still painful, but I'm a satisfied customer after witnessing the performance gain. Sorry this isn't more scientific, but I'll be happy to share pics or field questions.
