I see 17 GPH fuel flow full power takeoff with the boost pump on near sea level. The mixture control on my carb come out very far in normal cruise at any altitude. It is at least 1/2 way or more out at most cruise altitudes. It will take many tanks of gas to get the fuel flow constant adjusted to a value you like. Early on numbers and not very meaningful. The fuel transducer is 2.5% accurate. You should be able to adjust the constant it uses to get that close at ONE and only one power setting. I record all fuel used in my airplane in a spreadsheet and reset the fuel totalizer every fill. I only check the constant once a year now and it sits right at 3.5% more fuel used than what I purchase over the course of a year. Yes I could adjust it more to get closer but I like the idea of having more fuel than what my instruments tell me. Gary A. Sobek "My Sanity" RV-6 N157GS O-320 Hartzell, 1,956 + Flying Hours So.

These techniques work best with fuel injected engines, but are also applicable to carbureted engines.

Bob ================================= Bob: YES - Filtering is done on both wings right in the cabin BEFORE it gets to the fuel selector or the fuel pump. I used LARGE clear plastic auto motive type. Make sure you install it in the correct direction and CAREFULLY take a Xacto Knife and remove and flashing around the in & out fittings. ALSO - Make sure you de-burr the ID of the cut fuel lines. You don't want to reduce the flow due to the rolled in burr from cutting the lines. I am one of those that do not believe in the Gascolator ... I do believe in a LOW POINT collection point and drain. I have seen two problems with the Gascolator, one is brand related in that it would NOT open and takes quite a bit of twisting force on the firewall; the brand is the ANDAIR. The other problem I have seen is when the cowl was installed ... The hole in the cowl did not match to the Gascolator and since it did not the drain/purge function of the Gascolator was lost. Pump servicing - Best would be to move the pump to the forward side of the firewall. Other than that ... towels.

I don't have much headroom in the RV4 so I bought a Panther headset that uses custom earmolds. The headset fits perfect and is Sooo comfortable, on the ground it works great, but above 1500rpm and the mic feeds all the noise to the intercom and radio. The earmolds block out as much noise as our Telex ANR and Bose ANR, but since the mic is useless I need another solution. I have been fighting with it since May and just today sent it back again this time with a recording of different headsets vs. theirs. I expect I will be getting a refund and will try something else. I was impressed with the ClarityAloft headset at Oshkosh, but it was not in an aircraft. I would have been impressed with the Panther on the ground. Any advise would be appreciated.

The only complaint I can think of is that during the test phase (experimental engine... little bit of tweaking) I was in & out often and hands would get a little dirty and soon you would have an ear piece that you really didn't want to put back in your ear. Fortunatly they come with spare foam ear-pieces. Custom earmolds are also an option, but I've not found that I needed them. I must admit that I was a new pilot at the time, so didn't have any bias toward conventional headsets as I'd only had a few hours using them.

Pressure changes from altitude can also be a slight anoyance. The mic and sound quality are the best I've ever seen. My Bose X is easier to put on and about the same noise cancelling but heavier and messes up the little bit of hair that I have. Both have their + & - and either make a great choice.

I found that I couldn't get my squeezer to reach the most forward rivet (near the already riveted on top skin). I couldn't figure out how to buck it effectively, so I decided to put a cherrymax rivet in. It seems quite solid. Have not done the other wing yet. Does that seem sound or should I drill it out and think some more?
