This is the real question that needs to be asked when you are considering which propeller to buy. I had an opportunity to test four different constant speed propellers on one aircraft. There were three different 2 blade propellers and one 3 blade propeller. This aircraft was owned by a friend who flew the aircraft. I just went along as the observer and data recorder. The original 2 blade CS propeller on the aircraft had been dynamically balanced on the engine. Since the plan was to leave the original propeller on the aircraft when we were finished with the testing, we did not removed the dynamic balance weights from the engine ring gear. All three of the 2 blade propellers had about the same vibration level during their flights. Then we flew the 3 blade propeller. On the takeoff roll and initial climb, I noticed the pilot was highly stressed about something. About mid field, as we were climbing out, he finally said that something must be wrong with the engine. That the engine wasn't producing power. We laughed about this later. We seem to expect a certain vibration level which can be directly related to the engine power. We don't even think about this. And it's not something that any instructor I have had has ever talked about. It's just there. I've been told that a 2 blade propeller has a 2nd order harmonic on the Lycoming engine. And the 3 blade propeller does not have the 2nd order harmonic on the Lycoming engine. What does this really mean? On another test sequence, I had an opportunity to again ride in a friends aircraft. On this friends Harmon Rocket 2 with a stock Lycoming IO-540-C4B5, we removed a 2 blade propeller and installed a 3 blade propeller. The 3 blade propeller made the Lycoming run like it was an electric motor, it was so vibration free. When we installed a second 2 blade propeller, the same old vibration came right back. At the same level as the first 2 blade propeller. So the question goes back to you, the builder/flyers. Do you want "turbine smooth" or "tractor engine"? Maybe I should have titled this: "How to tame the Lycomisaur" Regards, Jim Ayers ________________________________ Message 12 ____________________________________ Time: 09:24:11 AM PST US From: "Wayne @ Aircraft Engravers" Subject: Re: RV-List: RV forced landing --> RV-List message posted by: "Wayne @ Aircraft Engravers" Bert, After you tell the story on Sat. night can you post it here so that we can have the facts also?

Do the same thing with a 3 blade prop and it will take off and go much further with no tumbling before dropping to the ground. Does this make sense?

Do not archive Harry Crosby Pleasanton, California RV-6, flying! Harry, I should not have called it a bus bar. I think that led to a lot of misunderstanding and some flaming. A conductor was needed between the master relay terminal and the starter relay terminal. I then assumed that 4 inches of copper or brass material in the form of a bar would be used to make that connection, and that the starter current would be 300 amps. Right or wrong, I did the calculations based on those assumptions. This is not a bus bar in the usual sense, like one that connects a row of circuit breakers together.

Disconnect the jumper from the big terminal on the starter, run a wire from it to your starter switch, then a diode from the starter side of the switch to ground to prevent arcing in the switch or contactor.

The reason I ask is that with a 4, there are 2 power strokes per revolution. So logically the two blade prop could create the pressure wave in sync with the power stroke that could be felt by the pilot. However, using that same logic, a three blade prop would cause the same effect with a 6. But the reports that I have read say theat the three blade is always smoother than the two. I suspect that is due to less thrust per blade being passed back into the frame. Comments???

It should be good practice to use carb heat when the throttle is reduced on a carburetor engine. This occurs when we approach for landing. What harm or what causes those who don't use it to be motivated by their actions?

The one I had in my C172 would ice up in a heartbeat. I've been flying behind Lycomings since 1990 and have yet to get icing in the pattern that I could tell. Carb heat just isn't needed because of the way they've got things set up. In fact, the manual for my Cheetah didn't call for it, either. With that, I got used to not using it. Since I'm still using a Lycoming in my RV, I'd have to figure that it works like the one in the Cheetah. Actually, it does better. :-) Now, for you guys who are determined to use carb heat in the pattern, by all means do it. However, it's just like auto gas. You won't crash and burn from using auto gas. You won't crash and burn from not using carb heat at every landing. Please don't cut us down because we don't use it. Experience has shown that it's not needed like it is with a Continental.

Not that I have anything to offer, just that, after spending the night in the saltmud on the beach, then dangling by its cord and twirling in the rotorwash as the airplane was slung back to the airport, my dear old Peltor headset is becoming intermittent with mucho green, crusty deposits visible in the speakers, the mic, the volume control, and all the wiring disappearing into the insulation. Plus the mic boom is loose in its sealed plastic housing. Although it was dunked in early July, it kept working right up until last week. Initially, I considered just replacing the electrical parts, and the boom assembly, but the latter is no longer available. So, I have to replace it, and I initially wanted a Peltor ANR but the local avionics shop stopped carrying the ANR model, saying that it wasn't very good and not worth the money. Anyone have any experience to the contrary? Should be some out there as Van's sells both the passive and active models. Anyone modified their passive Peltors to active with Headsets, Inc. ANR kit?

HOWEVER when it happens and it will and has, if the carb heat is not on, it will be too late upon the engine stoppage to reverse the icing as the engine is not putting out enough heat to melt the ice as it forms. Then you are in a big heap of trouble and nothing you do after the fact will stop the icing. Carb heat only works as a preventative, not as a solution. You won't lose face by applying when it is not needed but you certainly will lose face if you fail to apply before it is needed and have top make that forced, engine out landing in a place not of your choosing. ----- Original Message ----- From: "LarryRobertHelming" Subject: Re: RV-List: Carburator heat on rvs > --> RV-List message posted by: "LarryRobertHelming" > > Sorry if anyone thought I was cutting them down.

[JEC:] I **think** I may have experienced the beginnings of carb ice twice in 12 years of owning the plane. Once in a very high moisture situation under reduced power and the second approaching an airport over a body of water (reduced power). In both cases, I am not sure ...just think it *might* have been just a little bit. My partner (former Cessna owner) uses carb heat always on landing so when she is in the plane with me and I am doing the flying I will use it as it makes her feel more comfortable. Since I trained in Cessnas (mainly 172's), I too was taught religiously to use carb heat. When I bought the Piper, it really bothered me that the POH said to NOT use it. So much so, I went out and bought a carb ice detector for the carburetor and had it installed. It is amazing how quickly **SOME** ice can build up and when it can build up. So much so the alarm became a nuisance and I now keep it turned off as there always seemed o be some on the ground while at idle although it did not affect the apparent performance of the engine. But for a while it helped me feel better. So to each his/her own. If I were in a Cessna, I would **ALWAYS** use it. In the Piper I rarely (if ever) use it unless there is a change in the sound/performance of the engine. In the RV6, I primarily use it when my partner is there OR if I have been/am doing a lot of slower flying down low. Your mileage may vary.
