Congrats on both successful flights. Also congrats on getting your issue with your lacking RPM figured out so quickly. Thank you for posting and keeping us all motivated. Finishing my private this week which will free up more time to be able to make more progress on my rotary powered Cozy to the point where you are at as well. I long for that day as do many on the list.

We got the plane up in the air again, there was gobs of power, the temps stayed low, no higher than 160 for oil and coolant, but CO in the cockpit reached 300 PPM so it was only one circuit of the traffic pattern and a smooth landing. That SS flex exhaust tube is getting replaced tomorrow with the inconel. Also going to make sure the firewall is well caulked.

 

 

 At full throttle the engine is missing a bit, I think it's too rich. The pilot was going to play around with it a bit but due to imminent danger of CO poisoning he decided to land it. I'll take it up on the next flight after some Van's familiarization flights and exhaust refit.

 

I'm using the stock 13BREW O2 sensor, Tracy- is that the one recommended for the EM2? It seems that the EM2 mixture graph shows about 3/4 rich, so I lean it out slooooowly, and it doesn't have a sweet spot- it just goes to about 1/3 scale. There seems to be no in-between.

 

But, the plane flies nicely, like an RV should.

 

Next flights will be in a few days.
