I'm now trying to solve the...

Vortex Generators

I had them installed on my 73 T337G when I bought it. Since I had no experience with the ship before they were installed, I can't offer a comparison.

Thanks for replying, Mark.

Yes, you're right about needing only one Electronics International UBG-16. I misstated the case.

The UBG-16 can display all EGTs and all CHTs for both engines. It can...

Thanks, Jim.

Your experience gives me some comfort.

My mechanic likewise says the blade needs re-shimming, but it's OK for now. I"m going to fly it to a prop shop asap.

Best,
