From: "Dave Bigelow" --> Kolb-List message posted by: "Dave Bigelow" A few years back, I did the first test flights of John Pitre's Twin Star on floats at Kaneohe Bay on Oahu. Part of my checklist was to run the elevator trim full nose up and full nose down to check control stick pressure. His particular Twinstar had a single cable that ran to one side of the trim tab control horn. The other side of the control horn had a spring. As you added nose down trim, the cable loosened and the spring pulled the tab up. I don't know if this was standard from the plans. Right after rolling the trim wheel full forward and slacking the cable, the aircraft started shaking violently. I looked back and saw the elevator fluttering back and forth several inches very rapidly. I rolled the trim wheel back nose up and the flutter stopped. I have no doubt that the tail feathers would have failed in short order if the fluttering had not been stopped. My take on this is that any movable trim tab on the elevator should be built in a manner where there is always a positive connection to the horn with no springs or bungees. I'm not sure what would happen if the connection to the tab horn ever breaks or becomes disconnected, but I believe the chances of catastrophic flutter are high. -------- Dave Bigelow Kamuela, Hawaii FS2, Rotax 503 DCDI Read this topic online here: http://forums.matronics.com/viewtopic.php?p=13885#13885 ________________________________ Message 12 ____________________________________ Time: 01:14:58 PM PST US Subject: Kolb-List: Re: best price on 503 From: "Dave Bigelow" --> Kolb-List message posted by: "Dave Bigelow" Larry, I'm in the process of converting my Firestar 2 to twin Hirth F-33's. I took off my 503, but am keeping it until I'm done testing the twin installation. I have the engines mounted, but still have to work out the throttle hookup, hook up the fuel system, and do the wiring. I'm thinking about two months more. The 503 has 50 hours on it, and has never been overheated, seized, or in any way been abused. It has a B box, twin altitude compensated carbs, powerfin two bladed prop, and comes with a 503 "Smart Single" digtal engine monitering system and an analog tach. It's completely ready to go except for the engine mounts, which can be obtained from Kolb or elsewhere. I used this engine to climb to 16,000 feet, and it never has missed a beat.
