Hello Mike,
The primary difference betweent the two generations of 36 model Bonanzas is the yoke and throttle configuration. 1984+ models have levers to control the engine and two seperate yokes coming from the panel. Their panels are generally all metal with a more orderly engine guage stack and more ergonomic switch layout. Pre 1984 models have vernier engine controls, a dual yoke system that is interconnected in front of the panel and mounted on a single shaft coming from the center of the panel. Their panels tend to have a bit more plastic and/or wood grain components and are a bit less ergonomic in their layout. If you are planning a glass panel upgrade and don't mind (or possibly prefer) the vernier controls, then the "old panel" Bonanza offers a great value. The IO-550 engine replaced the IO-520 engine at that block point as well. I have a lot of experience with both engines and they are both great... as long as you treat them right.
I'd be happy to visit with you about any other questions you have and about any of our preowned Bonanzas that are in stock or expected to be traded in over the next few months.

Best regards,
Trevor

Mike,

Welcome to BT! I was where you are earlier this year. I had 60 TT in my logbook and bought a 76 A36. I had to do 25 hours of dual in it for insurance, and I needed it to feel comfortable as well. I just finished my IFR in it last month. Insurance this year was bad news, but with well over 100 in type and the IFR, I am looking for a significant drop in my premium next year. I have loved every minute in the Bo, and you will too!

While I ended up getting a V just because it is so darn sexy, I originally thought I was going to be going after a post-84 for the "updated" control layout. After looking through hundreds of pictures of both styles and taking some rides I decided that I really liked the single yoke - it really opens up the area around the wifes seat.

I also prefer the vernier controls, albeit only slightly. You lose the big iron feeling of the larger throttle but do gain some precision. It takes me slightly longer to get the prop and mixture forward on the go-around.

I actually have come to accept that the flaps on the left and the gear on the right is probably how it should have been done. You need a deliberate move to go for the gear and the flaps can be reached while still in contact with the throttle. (I now use Max's method of having the pinky around the throttle whenever flaps are touched). Mooney probably did it right by putting the gear switch way up high, but having the gear switch on the right is not a big deal.

The big yoke could be viewed as a liability as it does block some things (like the gear indicating lights when the dual yoke is installed), but I also think it makes a great platfrom for mounting my 696 with the Angerole mount. If needed, having the dual yoke option is nice (I borrowed one for my initial training) but if you are going to be doing all the work from the left seat, going single yoke is an option you can only really get in a pre-84'.

Fortunately, this is a great game.....there is no wrong answer, whatever you choose will be an outstanding plane!
