PITA ( not PETA)

Yes, that's what my FAA inspector thinks also.
Then I am close to order the ECT204. There are several options for the probes. Do you know which ones I shall order for the M10's C90?

- EGT: 1 1/2", 2", 2 1/2" clamp or weld-on bayonet?
- CHT: 12, 14, 18mm ring or bayonet?

Thanks!
Laurent.

Thanks for your replies.
@Mike: that comforts me in my idea that there is a mistake in Aerospace Logic's AML.
- Univair Type Certificate : "Ercoupe 415-D, E, F, G, Forney F-1, F-1A, Alon A-2, A-2A, Mooney M-10"
- Aerospace Logic's AML : "Univar (sic) 415-D, E, G, F-1, F-1A, A-2, A2-A, M1" !

Then why did Aerospace answer my mechanics that "The M-10 is not on our AML as there were so few of them made"...?

I too have an EI unit but it's the EC-1 with 4 channel selector so it doesn't have the nice graphic display but does do all 4 cylinders. Their CGR-30 is what I would look at for the graphic, but it's more $$$ than your considerations.

In the US, the Electronics International UBG16-4 is STCed into the M10. Look under Univair, not Mooney. I have one in my 690001 M10 and it works fine.

Look at our type certificate which covers all models from 415-D to the M10. You can find it on the univair website. Earlier, I said it included the 415-C/D, but that is incorrect.
