I had shot a video with cockpit audio showing how I do slow flight, stalls, more.
Plugging in the cable should have been on the checklist.
I am planning on "re-shooting". Any requests regarding my cockpit\701 operations?
Any other requests?
Last week the Seattle area became unseasonably cold. During the past three years that the 7-Oh-Fun has been flying we had not seen temps in the 20s.

That leaves only 11 public airports in Western Washington that I have not landed the 701 at.
So here are the facts:
1) My engine is back together and the plane is flying again
2) The only parts replaced were CHT probes, seals, gaskets and overflow bottle.
3) Compression is 86,86,86,85
4) Full root cause is still not fully known.
Between myself and my Rotax guru A&P we have a probable cause:
1) A near gross load reduced climb & cooling performance allowing for increases in coolant and oil temps.
We are still trying to figure why exactly all the coolant came out. The best hypothesis is an airlock developed in the system and forced the coolant out.
That still leaves us wondering why the airlock started in the first place.
Once piece of the puzzle has been figured out, which sadly creates a new question. The bottle failed due to exhaust heat. We were seeing EGTs close to the yellow\warning zone before the failure. The portion of the bottle that melted was…Continue
