I have no intercom at all. I have the SL15M with jacks wired to the panel. There are two PTT buttons wired off the jacks. One is on the panel (co-pilot) the other on the stick for the pilot. My headsets are Bose. There is no side tone in the headset unless you press the PTT button. I am reading something in the SL15 installation book about when the PTT are installed between the jack and the headset where it would need to be modified. I am not real good at this stuff, so not sure what is going on. Any ideas or thoughts would be appreciated.

After plugging every possible hole I could find in my baffling here are the results. Yesterday was quite cool here in East Texas and a flight was in order. After take off I climbed over the lake at the end of the runway and noticed the CHT on # 3 was over 400. By the time I reached 2500=92 AGL the temp was at 446 degrees so I leveled off and allowed it to settle out. After a few minutes the temps came down to about 406 but was about the same on 2, 3, and 4. I landed and removed the top cowl so I could block off the oil cooler by about =BD of the distance exposed. After another short flight the temps did not go above 412 on climb and then about 402 on cruise. The big difference was now cylinder #4 is the hottest. The oil temp climbed from around 154 to 182 so this was positive for this time of year. My oil cooler is mounted to the back baffle on the left side of the engine. I am at a bit of a loss for why the temps will not come down. One of the solutions offered was to add louvers to my lower cowl to increase exit air area. I am willing to do this but have some reservations. Increasing exit air would increase air flow through the cowl but should increase drag and therefore performance. How significant would this be? Obviously I would be willing to give up a little performance if I can keep it cool. Also it seems odd that hundreds, maybe thousands of RV=92s are flying and staying cool enough without louvers and so I wonder what else I may be leaving unchecked. I am convinced I have no leaks at this point. Here is what I have done: Closed up all leaks in baffling especially around the front and around the upper ramps. Added a deflector in front of cylinder # 1 RTV around every crack or seam where air could exit Plugged a big hole between the case and #3 in front of dipstick housing Blocked the heater exit on the right side of plane as it was pulling air from #3 ( I have two heater muffs.) My baffle is very tight and I see no areas where there could be a leak. I do notice the area above the cylinder on the right side is much less since the cylinder is further forward and under the upper ramp. Maybe this could be modified to raise the upper ramp some and equal this out. Because my temps change accordingly when I takeoff, cruise, and land I think the probes are at least responding. I also think since blocking the oil cooler caused a change and now #4 is hottest indicates they must be working. There is no setting on these that I am aware of, but maybe I should have the system checked out by Vision Microsystems to verify they are reading correctly.

Lycoming about 30 years ago had a problem with cylinder heads flying off of a few IO-360s with very old cylinders, in cold weather, where the engine was producing more than rated power. So they decided to retard the timing for IO360s from 25 to 20, which meant the impulse coupling or retard breaker also had to be advanced 5 degrees so you still start at TDC. They did this through a Service Instruction. I don't know that they changed anything for the 8.5 compression engines like the O-360. On most newer IO360s you will find 20 degrees called for, but older ones take 25(and produce more power). Steve Struyk wrote: > List, > > I just did my first annual condition inspection.

I would think that besides the heat transferring more quickly from the liquid to the probe than from air, the probe would never know. Besides, having the probe and themometer in a common container of liquid fairly well ensures they are at the same approximate temp. I would suggest caution how deep into the liquid you immerse the probe since I'm not familiar with how they are sealed- just part of the metal barrel on the end of the probe in the liquid should suffice. Possibly heat a very small pan of peanut/canola/corn/whatever oil ("you put my good candy themometer in USED MOTOR OIL?!?!?!") and heat until 400-425 degrees or so as indicated by the themometer. A meat thermometer would probably work as well. Take it over to engine where you already have the probe dangling and just dip the first half-inch or so into the oil. I'd think you'd have it warmed up to oil temp in 20-30 seconds, but again, I've never tried this- someone else out there could probably offer more specific advice.

It therefore changes the retard timing so it fires at DeadTopCenter rather than 25 degrees Before DTC. The impulse mag can have different settings. Some fire at 5 degrees before DTC and some at DTC. If you ever might hand prop your engine, you want the DTC impulse mag to reduce chance of a kick back which is bad for your starter. Indiana Larry ----- Original Message ----- From: Konrad L.

Lycoming about 30 years ago had a problem with cylinder heads flying off of a few IO-360s with very old cylinders, in cold weather, where the engine was producing more than rated power. So they decided to retard the timing for IO360s from 25 to 20, which meant the impulse coupling or retard breaker also had to be advanced 5 degrees so you still start at TDC. They did this through a Service Instruction. I don't know that they changed anything for the 8.5 compression engines like the O-360. On most newer IO360s you will find 20 degrees called for, but older ones take 25(and produce more power). Steve Struyk wrote: > List, > > I just did my first annual condition inspection.

DICK Martin RV8 N233M the fast one ----- Original Message ----- From: Tim Bryan To: rv-list@matronics.com Sent: Sunday, December 10, 2006 11:29 AM Subject: RV-List: Continuation on High CHT problem I reported on these earlier and received lots of great info and solutions. After plugging every possible hole I could find in my baffling here are the results. Yesterday was quite cool here in East Texas and a flight was in order. After take off I climbed over the lake at the end of the runway and noticed the CHT on # 3 was over 400. By the time I reached 2500' AGL the temp was at 446 degrees so I leveled off and allowed it to settle out. After a few minutes the temps came down to about 406 but was about the same on 2, 3, and 4. I landed and removed the top cowl so I could block off the oil cooler by about =BD of the distance exposed. After another short flight the temps did not go above 412 on climb and then about 402 on cruise. The big difference was now cylinder #4 is the hottest. The oil temp climbed from around 154 to 182 so this was positive for this time of year. My oil cooler is mounted to the back baffle on the left side of the engine. I am at a bit of a loss for why the temps will not come down. One of the solutions offered was to add louvers to my lower cowl to increase exit air area. I am willing to do this but have some reservations. Increasing exit air would increase air flow through the cowl but should increase drag and therefore performance. How significant would this be? Obviously I would be willing to give up a little performance if I can keep it cool. Also it seems odd that hundreds, maybe thousands of RV's are flying and staying cool enough without louvers and so I wonder what else I may be leaving unchecked. I am convinced I have no leaks at this point. Here is what I have done: Closed up all leaks in baffling especially around the front and around the upper ramps. Added a deflector in front of cylinder # 1 RTV around every crack or seam where air could exit Plugged a big hole between the case and #3 in front of dipstick housing Blocked the heater exit on the right side of plane as it was pulling air from #3 ( I have two heater muffs.) My baffle is very tight and I see no areas where there could be a leak. I do notice the area above the cylinder on the right side is much less since the cylinder is further forward and under the upper ramp. Maybe this could be modified to raise the upper ramp some and equal this out. Because my temps change accordingly when I takeoff, cruise, and land I think the probes are at least responding. I also think since blocking the oil cooler caused a change and now #4 is hottest indicates they must be working. There is no setting on these that I am aware of, but maybe I should have the system checked out by Vision Microsystems to verify they are reading correctly.
