A mag has a duration of 5 degrees rotation of the crank. The longer spark keeps igniting the unburned fuel which is spinning atomized as it travels by the spark plug. The longer spark therefore delivers better fuel efficiency and a power increase, both factors I can verify with data. I also like the fact the the ignition has a vacuum advance like a car unlike mags which are welded at 25 BTDC. At altitudes above 8K I have seen 38-40 degrees advance further increasing efficiency. It is also very, very smooth. There is no mag drop when you switch off the mag. It simply "augments" the EI inflight now and adds redundancy in case of failure. . My system has 1000 hours and still works wonderfully, I simply change the 14mm Denso automotive spark plugs every 100 hours, they only cost $1.25 each, it's cheaper to replace them than clean them! I don't recieve anything from electroair, I just like their system enough to give it my blessing. Go to the website or call them, you will like it!

I have 1300 hours on mine, absolutely no problems & I get 163 KTAS on 7.5 GPH on a C/S 0-360 RV 4. I might add the Auitolite 386 plugs are OK, however I had, as well as three others I know of, cracked Autolite 386 plugs when used more than 100 hours. Use aircraft plugs or Nippon Denso W27ESR-U with adaptors from Aircraft Spruce or change the 386 plus at least every 100 hours.

As a fixed or adjustable tab. Also, anyone know if VANS have ever implemented an offset rudder on the -4 like on the _7 and -9? Rear seat heat. have you fixed the problem. I was thinking of solving it with an electric seat heater but have no idea of the current draw. thanks, Steve. ----- Original Message ----- From: "rob ray" Subject: RE: RV4-List: Brake Lines > --> RV4-List message posted by: rob ray > > MIke, > We followed the plans on my RV4 and utilized teflon plastic brake line > throughout my RV4 and like magic at 1000 hours (5 years) they began to > leak.

Then flexible lines from the firewall to the master cylinders. The 3/16 stainless is real easy to work with for routing purposes and is adequate diameter to pass enough fluid for the braking needs...........and very strong. With two rv-4's projects completed and one -10 coming up, 3/16 line is all I will ever use for brakes. You will end up using -3 fittings on the lines. Hope this helps. Personally, I can never trust my braking to plastic lines of any sort. Fine for low-pressure needs only.

The efficiency of a heating element is about 100% - all the current goes into heat either in the element or the wiring going to the element. So at 14V, probably 2-5 Amp. Doesn't sound like a big draw. Let me know if you can find an element. One industrial supplier is Watlow. I integrated 12V heaters into vehicle equipment designed for Alaska market. Don't know about small quantities, but their element would do the job.

As a fixed or adjustable tab. Also, anyone know if VANS have ever implemented an offset rudder on the -4 like on the _7 and -9? Rear seat heat. have you fixed the problem. I was thinking of solving it with an electric seat heater but have no idea of the current draw. thanks, Steve. ----- Original Message ----- From: "rob ray" Subject: RE: RV4-List: Brake Lines > --> RV4-List message posted by: rob ray > > MIke, > We followed the plans on my RV4 and utilized teflon plastic brake line > throughout my RV4 and like magic at 1000 hours (5 years) they began to > leak.
