I have an old aircraft directory that says the Queen Air Model 88 was the only version pressurized. It also says the basic model (65) used 35 gph at cruise. I'll assign that to the case of 65% at 8500 ft. i finally have the Queen Air flying well with good numbers. It took a long time to get the power right. At first I was seeing 100% power at 67% throttle and the RPM could not be set independently of the throttle. By reducing power considerably with a 57% scalar, I am able to get all the proper numbers for this turbocharged model. The RPM can now be adjusted independently of the throttle for most of the power range (above the lowest settings used on the ground).
The Power Panel was very useful in working this out. It shows running values of all parameters pertaining to power. It is on my web site. (It is only used for testing.)
I sent you the FD for the 182RG and P210 in case you want them.

Thanks--I'll look for them.
Jane's A/C also mentions a Queen Air 70 that was their "airliner" configuration. My stuff is at home, but they must have put in extra seats.
Now that you mention the "88", I think that they made one, then decided instead to bolt on a pair of PT6s and rename it the King Air. The rest is history!

Here's another question that can only be answered in Jane's. How many fuel tanks does it have and where are they. This model has three - right, left and center. Most later Beechcraft twins had four with two center tanks in between the engines and two outer wing tanks. I had starting problems because I put all the fuel into the center tank and could not select it.

Oops. To get back to the title of thise thread, speed change is not a pure indicator of landing gear drag. I added the drag and tested that it does slow the aircraft under a case where you are level at gear speed with constant power and flying level using the autopilot. But while adding gear drag I also added nose-down pitching moment, perhaps a bit too much. In free flight in on approach, lowering the gear causes a downward pitch which increases the airspeed slightly. I'll have to work with that a bit more.
