Low air flow is an issue for the Enviro systems. With the Sundstrand, it's never an issue-- I can turn one bleed off, and the cabin never bumps. So leakdown might be an issue for you.

In my case, I was told that the pressurization controllers have a certain tolerance, and some of them will only go to 5.0, some will go to 5.2. If I wanted to spend a bunch of money changing controllers until I found one that went to 5.2, I suppose I could do that, but 5.0 is good enough for me. At FL280, I have about a 10,500 - 11,000 foot cabin, and that doesn't bother me.

Don - Itís outflow valves more than controllers in my experience.  Honeywell doesnít seem to like to deliver valves that do what they should.

I think that's right-- it's the outflow valves. I'm sure they have a manufacturing tolerance, and mine are probably just at one end of that tolerance.

I remember picking up a new Citation Sovereign at the factory, and when you put the speed brakes out, it rolled to the right. The Cessna test pilot said that it was within tolerance, or something like that... I asked "Do they all do that?" He replied "Well, no, not all of them."

When we landed, we talked to the production guys, and they said they just pulled the speed brake actuators out of the box and put them on the airplane. The actuators were built with a certain tolerance for how fast they worked, and if one was at one end of the range and the other one was at the other end, there was a pretty substantial difference. So they agreed to go back to parts and pull a bunch of different ones and find two that were about the same. Roll problem solved.

I have always checked out photos of the twin turbo commanders online.  Seems the 980 model has x2 paint schemes that are pretty unique (granted there is a flying dolphin on a 690 I believe!).

The last one lives in Germany and is owned by an older gentleman. I had a guy contact me a few years ago in Germany interested in a Turbo Commander. I managed to connect the owner of the space one with this younger buyer and they went for a ride. He liked it, but wanted something newer in the end. But funny how the Commander world is kind of all within reach.
Slumming it in the turboprop world - so you don't have to.

Didn't the guy who got a ride in the German spacey 980 post about it here somewhere?

Yeah, he did. Don't think he's logged in since.

The yellow mouse one is Truly Nolen, which is a pest control company in California and Arizona (and maybe other places?).

They usually have some sort of old car out front of their stores with similar paint, and I think their trucks are also painted that way.

Afternoon everyone.  Know it was mentioned in a previous post, but figured I would ask (maybe Bruce knows).
Im in the market to buy an original model of the 980 that the manufacturer gave to owners at purchase.  I know Don had one sitting in his office for many years.  I've looked online, and the one I previously purchased is nowhere near the quality or detail of the original we got.
I know its a long shot, but nowhere else to look.

I really don't know... there are probably some sitting around in people's offices-- the irony is that it's worth a lot to you, and someone who has one might be putting it in a box for Goodwill or something!

So true Don- would actually pay pretty high price.

I checked with the one person who I thought might have one, but it disappeared long ago.
