I would say the custom plugs are not expensive at all relative to the quality of the product. They are basically made to fit your plane, have N-number attached and are very durable. It takes nearly 2 months from the time you order them til delivery. They will also ask for pictures after your order to verify the pattern they need to make.

I was curious because I'm thinking about the sky beacon now and then getting the other wing tip when uavionix releases it. Has anyone installed the SkyBeacon on an M20C yet?

Any reason why you are opting for the tail mounted version vice the SkyBeacon?

Resurrecting this thread because it has become relevant again. Last year I started this thread because my dimmer switch wasn't working and when I went back to the hangar to take pictures etc it miraculously was working. Well...fast forward to now and its NOT working...so I will go back to the hangar and get pics this time...hopefully taking pictures of the switch will make it work...if it doesn't I will post some pictures and let everyone know.

How many AMUs dues the DIY kit run?

The plastic panels in my airplane are good but the sidewall carpeting is starting to deteriorate a bit. Are there vendors with pre-cut carpet? What seems to be the preferred method of keeping the carpet in place?

Farris Aviation in Ridgecrest has an instructor with those quals. 760-301-4522 Instructor is Brian Cepaitis. Not sure what his going rate is these days.

Apologies for the necropost - but I could use an electronic copy for a 1965 M20C Owners Manual. Anyone have an eCopy?

I think the biggest problem most of us have is the orphaned STC for new installations.

Oil fouling and black oil but good compressions is likely a worn ring issue. On a high time C model its likely that it ran a bit "hot" over its 1800 hours but that is just guessing. I have an email from Mike Busch saying that this condition is not really a major issue other than its a pain in the butt and you always risk having plugs not clearing if they get oil soaked. The lycoming run up procedure should be followed: https://www.lycoming.com/sites/default/files/Magneto Drop-Off.pdf Leaning the motor slightly during this run up seems to increase the EGT enough where it burns some of the oil off. The fix for the oily plugs is to have new rings installed or new/overhauled cylinders. Another symptom you may see is that you are blowing lots of oil out of the breather since you are pressurizing the case due to blow by. You may also have a stuck ring or two and these can be freed with a solvent ring wash...your A&P should know how to do this as well. I'm not an A&P.

#3 cylinder fouled due to lead fouling or oil? Lead fouling can be somewhat prevented with the AGGRESSIVE leaning on deck. Oil fouling is a different problem. What were the condition of the spark plugs when you pulled them out to replace them? Clean and dry or oily? Does your oil get black quickly after an oil change?

Anyone here every done this work and have an estimated cost?

Is this compatible with any STEC 30 or does it require a specific HSI etc?

Where is this deal?

What are your fuel flows at those settings?
