Aircraft microphones are designed to be noise cancelling by having holes on both side of the mike. With the mike pointed directly at your mouth and square to your mouth, your voice is picked out of the noisy aircraft cabin. Ronnie Brown Time: 11:00:48 AM PST US From: "Vic Jacko" Subject: Re: RV-List: Microair 760 --> RV-List message posted by: "Vic Jacko" The intercom with the current Microair is either on or off depending whether you ground or un-ground the correct pin for intercom. When the pin is grounded the intercom is live. when the pin is un-grounded the headset is dead with no noise except what might be received on the radio receiver. I heard of some transceiver system (can't recall) that has a squelch built into the intercom which is part of the radio intercom system. It might be the new Becker! anyone know ? Yes the system is noisy when turned on but so are most other systems when you break the squelch and talk. They all pick up cockpit, air and engine noise. some more than others Vic ----- Original Message ----- From: Subject: Re: RV-List: Microair 760 > --> RV-List message posted by: Fiveonepw@aol.com > > In a message dated 1/10/04 8:11:24 AM Central Standard Time, RVEIGHTA@aol.com > writes: > > > Since you still have a hot mike, > > doesn't it pick up ambient noise, making conversation difficult? > > But don't you still have to break squelch for the sidetone/intercom to > function, and therefore no ambient noise when not talking? > > Mark > > ________________________________ Message 6 _____________________________________ Time: 07:25:41 AM PST US From: "Cy Galley" Subject: Re: RV-List: More Starter Suff --> RV-List message posted by: "Cy Galley" to get more teeth the ring gear must have a large diameter.

Yes, the engine is a big air pump, and MP and RPM are definitely the major factors in determining how much power is produced. But we can't ignore the altitude. The higher the altitude the lower the exhaust back pressure, so we get better cylinder scavenging and more power for the same MP and RPM. For example, looking at the Lycoming O-360 power chart on curve 10350-A (this may have been replaced by a different curve in later manuals, with slightly different powers, but the principle is the same). If I use 2400 rpm and 24" MP, and assume standard temperatures - at sea level I get 136 hp and at 5,000 ft I get 147 hp. If I look at 2500 and 20", I see 107 hp at sea level, 117 hp at 5,000 ft and 123 hp at 8,000 ft. So, altitude matters, and those rules of thumb that purport to calculate percent power from MP and RPM are not worth much. Fuel flow is a much better measure of hp, as Mel originally noted. Using fuel flow to determine power produced does assume you lean using some repeatable technique, as the specific fuel consumption will vary depending on whether you are at full rich, leaned to best power or leaned to max economy.

All nine were happy with performance of radio with comments such as crisp & clear at 75 NM, and picks up ATIS farther out than Garmin GPS/COMM. One user was 50/50 on radio, good performance but not happy with having to send to Australia for warranty work. Built in Intercom seems to have a problem with cockpit noise but so does my Apollo SL-60. I will watch progress on Xcom and if they miss their production date again I will buy the Microair.

I made the same mistake on my -6a you describe. I chose to drill out the entire brace and replace with a new one. That way hole spacing is not a problem. BTW, I don't quite understand when you say your flap is 3/8" "too high"... It should just clear the top skin by 1/32" or so. Are we talking about the same dimension? By "too high" you must mean the flap won't even begin to fit under the top skin... Sorry if I'm dense...
