KRviator

Strictly speaking, the "Emags" are their original design that requires ships power. Their newer version, "PMags" have an internal alternator that takes over from ships power at anything above flight idle. This is what I have in the RV, twin PMags, and granted I only have around 100 hours on the RV so far, but I have yet to have an issue with them, and if I could, would happily install them in any certified 4 cylinder aircraft I owned. If I were to build another Experimental, I would install EFI with twin ECU's and a backup alternator in preference to the TBI and dual P-Mags though. The efficiency and ability to trim fuel to the individual cylinder make for remarkable performance gains.

Do you know why that is? I have dual EI on my RV-9 that I'm going to sell shortly to fund a 4-seater, and a -J is on my list, with EI being one of the early planned upgrades. The Electroair AML lists the M20-M20J's as being approved. I note Electroair do say they don't have a solution to completely replace the D2000/D3000 magneto system though.

Is this VH-VVA? According to CAsA, it's the only 1981 M20J based in NSW.
