These things are cool. If you hit the crystal (imput a force), they generate electricity as a function of the force. [Typical applications - gyros, cigarette lighters, old fashion TV remote controls that didn't need batteries] If you put power (hook up electricity) to the crystal, the crystal moves. [typical applications - auto-focusers on camera lenses, and various other linear actuators] I would think that a vibratory gyro would not work very well in a high-ambient vibration environment. Maybe the software guys have a work-around. I don't know.

Getting rid of the bubble that sits in the compass window is more difficult and can be maddeningly frustrating. Fill something like a coffee can with the fluid, submerge the compass in it and keep rotating it until the air escapes is the advice I was given. Eventually worked too.

All you're doing is removing a plug and filling with fluid. Is your engine broke because you have to put oil into it? I just love the absurdity of some of the FAR's. I'm a firm believer in the 'don't ask, don't tell' environment. If you're capable of removing and replacing screws without wringing them off .... then I say go do it. It really is rock simple.

I like the idea of less resistance as I am building an 8 with the battery in the back, but, my dutch genes rebel against the price for little appearant improvement. Yes you can throw calculations all day long showing a little weight saving (about a pound and a half) and less resistance, fact is there are plenty of RV8's out there with a rear battery and #2 wire with no problems.

First, at low power settings (say, less that 14 in. MP) I am getting occasional popping from the exhaust on my O-360-A1A. I have the Van's FWF kit and exhaust. Everything seems tight on the exhaust system. The occasional popping reminds me a lot of my old GSXR-1100 Suzuki's exhaust when backing off the throttle. My suspicion is that the low backpressure exhaust system has something to do with this, and that it is not a problem per se, but I would appreciate some feedback. The archives had very little on this topic. Second, what CHTs are people seeing? I have the RMI MicroMonitor with bayonet probe in #3 cylinder. So far, I'm showing about 340-380F in cruise, the latter numbers being at, say, a 24/24 power setting and the lower at perhaps 20 inches/2300. But in climbout I am seeing anywhere from 390-430F flights have been from sea level up to about 4000MSL, on days with close to standard conditions. I think my baffles and seals are "pretty good," though I'm sure there are a few small spots that could be sealed better. Oil temps have been fine with the Niagara cooler. Any thoughts are much appreciated - TIA. John H.

Good luck getting it to seal again, even with a new gasket, even with two gaskets, Fuel Lube, or Pro-Seal. Change the rear diaphragm, as it may indeed have a tiny pinhole, and go with the "plunge in a tin of alcohol and roll around until no more bubbles come out" method of filling.

It concerned the tachometer transducer that VANs sell for their electronic tach. I followed Mel's experience and when it came time to set my EIS to the number of pulses per revolutions, I just assumed I should use the same value Mr. Jordan has found to work. Well, to make this story short and cut to the chase, I just have these lessons for anyone who is considering this route: 1. The transducer works really well (so far). 2. Maybe it is a different model transducer, but the important thing is to check for yourself how many pulses per revolutions YOUR system puts out. I am not even going to tell you the number I have, so that no one will be tempted to blindly follow this number like I did with the number Mel has found to work for him. Borrow/buy/steal a tachometer you can cross-check with. Thats all I had to say. No damage done, just a lesson learned, and thanks MGM for letting me borrow your optical tach.

I thought it was alcohol as I'd read somewhere that ground troops would occasionally drink it. Or maybe I'm getting that confused with torpedo juice.

Wayne Stiles" I only get the digest and am a couple of days behind in reading them so someone may have mentioned this. but FWIW: In addition to wear and color problems, asphault can present some serious hazards when solvents are spilled on it. Some HAZ-MAT training I went through as a local vol. fireman thuroughly spooked me from putting asphault down for a garage or hanger floor. If I was forced to have an existing hanger with such a floor I'd get it sealed and then capped with a coat of concrete.

This combination is known to do this. It scavenging something aruther. Some cert planes like the pitts do this regularly also. A search of the archives will reveal lots of discussions on the topic. Mike Do not archive. -----Original Message----- From: owner-rv-list-server@matronics.com [mailto:owner-rv-list-server@matronics.com] On Behalf Of John Wiegenstein Subject: RV-List: O-360 Exhaust Popping, and CHTs --> RV-List message posted by: "John Wiegenstein" Well, now that the first two flights of the RV-6 are under my belt, I'm moving from "construction" questions to "operational" questions. First, at low power settings (say, less that 14 in. MP) I am getting occasional popping from the exhaust on my O-360-A1A. I have the Van's FWF kit and exhaust. Everything seems tight on the exhaust system. The occasional popping reminds me a lot of my old GSXR-1100 Suzuki's exhaust when backing off the throttle. My suspicion is that the low backpressure exhaust system has something to do with this, and that it is not a problem per se, but I would appreciate some feedback. The archives had very little on this topic. Second, what CHTs are people seeing? I have the RMI MicroMonitor with bayonet probe in #3 cylinder. So far, I'm showing about 340-380F in cruise, the latter numbers being at, say, a 24/24 power setting and the lower at perhaps 20 inches/2300. But in climbout I am seeing anywhere from 390-430F flights have been from sea level up to about 4000MSL, on days with close to standard conditions. I think my baffles and seals are "pretty good," though I'm sure there are a few small spots that could be sealed better. Oil temps have been fine with the Niagara cooler. Any thoughts are much appreciated - TIA. John H.
