Very Nice!! What engines are on this model?

Per TC 5A4, they should be 295 hp Lycoming GO-480-G2D6's...

I looked over and sat in this exact airplane (N66QM) once upon a time way back in 2008 when I was in Oshkosh WI doing a "pre-buy" inspection on a different airplane owned (at the time) by the same guy, warbird collector Jack Mark of MA Inc. in Oshkosh. It was in a huge hangar along with a Rockwell Sabre, Canadair Challenger, DC-3 with an executive interior, a DeHavilland turbine Otter on amphib floats (nose bleed time just checking the fuel tanks!)

That other airplane was the same turbine Goose, N642, that is on the cover of the most recent edition of SPA's Water Flying magazine - in all of it's newfound glory after a 10-year restoration by the guy who bought it a year after I looked at it. We passed on it due to its many issues - hence the 10-year restoration that was required!

I don’t need two Twin Bonanzas. I don’t need two Twin Bonanzas. I don’t need two Twin Bonanzas. All is well, remain calm!

This plane was converted to IGSO480’s. It’s super charged.

Yes, a nice "T Bone." But if it has the remote Air Wolf oil filters I can say that there is a much neater installation than those hose fed, space cluttering units. I held the STC for the engine mounted "Sunrise Filters" engine mounted oil filter system used on the "T BONE" airplanes that had the rear mounted engine accessories. After doing that for about 30+ years Air Wolf bought the STC's for both the GO 435/480 and the Continental E series engines used in the first nearly 5000 V tailed Bonanzas. They then sold all of the AIR WOLF held STC's to Covington Aircraft Engines in Oklahoma. Covington is now producing the original Sunrise units and has them in stock. Anyone that has used or just seen the engine mounted oil filter adapters will, or probably will, say how much better the engine mounted oil filter units are compared to the remote mounted ones. During the time I was producing and selling these units I had several people get one of the engine mounted systems and remove the remote mount unit they had installed.

And that is the rest of the story.

The AirWolf Spin on Oil Filter Adapters on N66QM are engine mounted and not the remote style.

I am glad to hear that. I developed the oil filter units for a friend of mine that had an A model Navion with a GO-480 (295HP) engine. He wanted an oil filter so I took a bunch of measurements and manufactured one for him. I was prompted by the "T" Bone Society to get the STC and add it to my PMA (I was producing [PMA] the Continental E series units at the time for Bonanzas). So that took about 6 months of dealing with the FAA and those units became available to those that had a Helio 295, "T" Bones and Navions and several other airplanes that had the rear mounted accessory O-435, GO-435/480 engines.

That Navion that had the GO-480 (295 HP) engine in it went on a number of fairly long trips with me in my 225HP ( for 1 minute during takeoff, actually 185 HP for cruise) G-35 V tail. He would really takeoff and climb like a rocket. At about TOC I would pass him up and use 2300 RPM for climb and then 2150 for cruise. I would be leaving him by about 5 MPH and he would ask me to pull the power back. So I would not, but say I did. About the third request I would say I was at WOT and 1900 RPM and not going any lower. That Navion would go as fast but needed to burn nearly twice the fuel flow to keep up with that old V tail.

Well, that is how those engine mounted oil filters came into being on the Lycoming GO-435/480 engines.

I have been primarily looking at Baby Barons...but this would fit me perfectly. Is there anything I should know about Twin Bonanzas in terms of maintenance or insurability?

There is an entire sub-forum just for the Twin Bonanza. That, combined with the search function, will get you just about any information you want to know. There's a current thread in the TBone forum on insurance.

Short versions:

1) Maintenance isn't particularly complicated or difficult, in part due to pretty easy access to most things. Condition of the flight controls is important, as they're (usually) magnesium and hard (expensive) to fix or replace. You'll be miles ahead on maintenance if you're handy with a wrench and willing to help your A&P with troubleshooting, parts sourcing and a little work here and there.

2) If you're insurable in a Baron, you're probably insurable in a Twin Bonanza. Check the insurance thread.

3) Other considerations: you need a hangar with 50' doors.

I had a baby Baron and upgraded to a TwinBo. Cost wise it's about a wash. The Tbone burns more fuel and goes a bit slower, but with the huge wing it lands slower, stalls slower (better short field/off field capability) and hauls a big load in space and comfort. Plus it oozes vintage charm, I get comments wherever I go. The bone has also been a bit cheaper to maintain because of the Lycoming engines vs Conti and just a big simple airframe that mechanics find super easy to work on. Oil changes for example are a breeze on the Bone, and I now do them myself whereas before it was so tight in there it felt like a job left to the professionals and I got tired of cuts all over my hands. They're great airplanes with a wonderful owners group on here that have created somewhat of a cult resurgence for the "craft of the masters". Insurance has been going up across the board, and now fuel too.

Once you get used to a 54” wide cabin, normal GA airplanes seem very cramped and silly, as in “why am I rubbing elbows with my copilot?”

Before I bought my TwinBo, I flew 170 hrs in a Diamond DA42. I thought it was fine…comfy and roomy. Then after 250 hrs in my TwinBo, I rode in the right front seat of a DA42 several times doing air-air photography, it was a miserable experience. Cramped, always struggling to avoid the stick, the pedals, the pilot.

In short, the TwinBo spoils you for normal GA airplanes.
