My experience differs considerably... with regards to TCs.
And I can show you exactly what I'm talking about.

The HD DA 1.4 TC causes a 3% loss in IQ. It increases size 40%. Appropriately used it will ad 37% more detail with the following conditions. The original lens cannot resolve the necessary detail at the distance from the subject.. The subject isn't so far away no lens will resolve the detail. The subject is in the zone between those two. The lens must be a DA* or equivalent. Putting a TC on a soft lens just magnifies the softness. Given those circumstances the increase in detail will be up to 37%, 100% of the time. The variable that makes this a less than hard number is how much of the necessary detail the original lens without TC doesn't resolve. If the original lens in your shoot is revolving 90% of the detail you want, the resulting increase can be no more than the last 10%.

Using a good TC is exactly the same as using a longer, slower lens. Longer lenses don't always produce more subject detail either, if the original lens already was resolving 100% of the critical detail.

Understanding folks saying a TC doesn't ad more detail. - PentaxForums.com

P51D Mustang at the Brisbane Valley Airshow

I don't have many photos of birds flying and probably none over 300mm but here's something flying that fits into this thread. K-1 and the 150-450 @ 450mm, the bright conditions meant the lens worked well for tracking and maintaining focus whilst panning despite my best attempts to get it wrong.

Beautiful picture and frame! A bit more prop blur would make it even better, but I really like it anyway!

Very impressive images everyone. I’m looking to get into the Pentax system for wildlife and I think you’re images have swayed me completely. I frequent forums with images taken with equipment by the other manufacturers and your images compete very well.

Do any of you have recommended settings for bird in flight shots with a k3 ii?

Try these..

Here are my current recommendations for BIF with a K-3. I have these set in USER1 mode:
TAv mode:
- Set aperture for sharpest MTF - f/5.6 with the DA*300, f/8 if you're also using the TC. Shoot at f/8 with 55-300mm, do not use a TC. If you're shooting in dim conditions, the DA*300 is acceptable wide open, even with the TC. The 55-300 is unacceptably soft wide open.
- Shutter speed according to conditions. I find 1/1000s works most of the time. Never go below 1/500s. Don't be afraid to push ISO. Noise is correctable, motion blur is not
AF-C, Hi-Speed continuous burst:
Center AF point, with 25 point expansion. I use 9-point for sports, but birds move too fast to stay within the small 9-point array.
Matrix metering, add 0.5EV compensation, fine tune in p-p
Shake reduction Off

Custom Menu Parameter Settings:
16. 1st frame action in AF-C - Focus priority (make sure focus is on the target before shooting, or you'll have a string of misses)
17. Action in AF-C Continuous - Focus Priority
18. Hold AF status - Medium, bump up to High if required. IME, AF Hold Off or Low allows focus to drift to the background too readily.

I only shoot raw, turn off all the jpeg settings (lens correction, NR, etc). Having USER1 set for action allows me to switch over from a still subject to action with just a couple of mode dial clicks. Highly recommended.

My feeder creatures, I got pictures of everyone who turned up but, not a lot turned up. It's warm day, every bird that came was pretty casual.

The last couple of days have been warmer and today I had a chance to go look for snowy owls and was not disappointed.
Here is a couple of them.
