Poll: If you were building an airplane today, which ignition would you choose?

[bertschb]

If you were building an airplane today, which ignition would you choose? If you would choose a mixed setup, you can vote for both.

The poll doesn’t specify between SDS ignition only and SDS EFI. Yet EFII System 32 is a choice.
I currently have dual SDS CPI2 but would use the SDS EM-6 if doing it now.

I'd go with what I have on the RV-10. A mixed system - one mag,, one SDS. The SDS gives you mechanical reliability and a very flexible advance curve for performance. The mag gives you independence from an electrical system

 

[andoman]

I believe the poll will be skewed by those that are partial to carbureted aircraft choosing dual mags….

 

[Full Throttle]

Will two votes be issued if I vote for Mag and other? That will skew the poll also.

I am building another airplane and unless something better comes along I’m going to install a SDS CPI 1. Light, inexpensive, maintenance free, and bulletproof. The airplane is a Pitts S1 and will be flown at full throttle and full rich for 45 minutes at a time. No LOP, no need for a complicated curve. Aside from a retard for start, the advance will likely be fixed like a magneto.

Interesting, but not surprising, the most unreliable, or say maintenance intensive, system is at the top...
Having a mechanical part driving another mechanical part to produce e-energy to fire the first one is, as proven thousandfold by the auto industry, an obsolete concept. The more so in the world of Experimental Aviation, but who wants to experiment nowadays?
