I wanted to know if anybody had successfully fabricated a home-made throttle quadrant.I have seen a few how to articles and attempts at it but wasn't sure if somebody had completed one that worked well. I wanted to build one with 3 levers (throttle, mixture, prop) that was similar to those used in WW II vintage a/c. I have actually found a 3-lever throttle quadrant for real a/c use that I think could be converted to PC use. I also have found an AT-6 Texan quadrant that I thought about using if the price is right. I know a few companies produce 3 lever quadrants but prices are very high ($200~$400) and they are civilian, general aviation types for right handed operation. I wanted a military style,left handed assembly for ease of use and added realism. Most of my questions are centered around what I need to use electronically to have 3 sliders as well as wiring concerns for a USB plug equiped PC. I know I'll need a cheap joystick or 2 as well for parts and the needed software to run them. Any advice or suggestions would be great.

If you are willing to spend some money there is a online retailer that sells actual avionics controls with digitial outputs for build it youself and to your style throttle quadrants, trim controls, etc. For more money you can get prebuilt ones with a standard Gameport plug or a serial plug,haven't seen a USB one though.

What is the extent of your electronics knowledge? Can you solder?

Yes, no prob on soldering. Actually my side job is at a hobby shop so I work with small scale electronics like motors and electronic speed controllers. I know enough to be dangerous I think. More info on the custom controllers like where to get them would be great. Thanks.

Look under "Hardware", you'll find just what you need.

For potentiometers, switches, and other dodads I can't recomend ebay enough.

some stuff to look at.
if you didn't want mixture it would be easy- but until we get that on an axis you're gonna need a usb device with the ability to program 'zones' for the button presses for mixture.
cougar definately does this- i've added pitch and mixture levers wired through the toebrakes..
i'm sure the betainnovations also can do this and i think it's possible with ch gear and x45?

an easy way might be to use/adapt something from here-

ch throttle quad?

as you work in a hobby shop you should be able to find some nice bits-tamiya r/c car gears work great for me http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif
wooden 'ball' door/cupboard handles work well for lever ends
oh and some sort of detent to stop mixture being shut off accidentely is a really good idea http://ubbxforums.ubi.com/images/smiley/35.gif

Thanks for the additional info Bolox00. I am actually planning on using a real aviation throttle quadrant as the starting point. It has all the levers and knobs already so the big thing is just getting it wired up and then mounted. I've found a 3 lever quadrant by ACS for about $45. Its a cheap starting point relative to what I've already seen and if I can just fit the electronics to it and make it work I'll be set. My concern with it stems from its compact design. There may not be enough room to fit the pots without taking it completely apart and just using the pieces. I've found an AT-6 quadrant as well. These are fairly large and roomy inside by comparison so this may be a better route to take. I guess I need to figure out what I'll need electronically so I know how big these parts are and then decide on a quadrant.

Does any one know if I could buy the insides of a PC throttle quadrant already set up for three sliders? I have seen them around and wonder if the manufacturers would sell pieces (for a repair work situation). Just a thought. Thanks in advance.

Did you guys ever try a website called Desktop Aviator? They sell Cessna style Throttle Quadrants and the price is not too bad.

I saw it done once with an auto transmission case and shifter linkage that a guy wanted to use for racing sims. Can't find any link to the old postings of it anymore tho. He had used magnetic reed switches in the linkage for input signals. That may spark some ideas for you.

How'd you do the labelling?

Here's a photo of Desktop Aviator's Throttle Quadrant. It looks really cool. I just received mine in the mail. Programming it with my FS 2002 was a snap. Now, I can control the engine's RPM, Fuel Mix and even the Flaps. I also ordered the optional Elevator Trim Wheel. Can't wait to order their Parking Brake.

This one is made of plywood of poor quality. Splinters of it flew in all directions when I used the router to form the halves using a template.You can see splinters missing on the backpart.

The front part has a photoshopped pattern(printed on paper, laminated in a common office laminator and glued on the frontpanel. The top is made in same manner.

Now I have made new front and backplates. The new ones are made out of laminated floorboard of 5 mm MDF with laminate on both surfaces. Left over from renovating some rooms in the house.

The plates are held apart by threaded rods inside aluminium tubes.
I'll post some new pics asap.

Hi Triggerhappy, you helped me a while back with my trim box (10 turn pots are definitely the way to go), now I'm after a bit of assistance with a throttle quadrant I'm building.

I was wondering how you translated the motion of a pivoting lever to a pot when you built your throttle quadrant. Obviously a rotational pot won't do the job because the lever won't move by more than about 60?. I was thinking along the lines of extending the lever past its pivot point and linking it to a slider pot. Some adjustment will need to be made for the length of the lever of course, depening on whether the slider pot is in the centre position or at one of the ends.

However, before I go ahead and start to build all this, I would appreciate it if you would suggest any better ways of doing this, or obvious mistakes that I should try to avoid along the way!

mmitch10,
There are pots which do indeed work over a 60 degree range. Joysticks have used 'em since the Earth cooled.

I believe you can still get such pots (good quality at a decent price) as replacements from CH Products.

In the middle of 2k6 a guy called Thunderboy he announced this incomplet/unfinished WWII style throttle in the SimHQ Buy/Sell/Trade forum,look as good start point:

I´m glad to hear you find the 10 turn pot so useful for trimming purposes. Sad to say but the throttle quadrant in my pics never made final stages.... Ive made a new one on pretty much same configuration tho, but not yet finished. As I´m studying for my batchelor degree in education, the time for building things isnt there at the moment.
But as the pictures Sokol provides, show, the best model would be to travel the lever motion away from the throttle unit to an additional box where to put the pots and some geared mechanism.
I, my self are planning to do so by using wires used for operating bicycle brakes and some sprocket wheels to determine sufficient travel of the pot. I´m no fan of short travel pots as the travel of the viper in the potentiometer is so close connected to the resolution of the movement. The longer the travel - the better resolution. I've made mock-up tests tho. Using full travel of 270 degree pots and a 20 cm lever traveling some 40 degree arch. The resolution of such a mock-up throttle is just something else compaired to my x-45 throttle.
you can compaire it with using 10 turn pots for trimming. The control of the throttle becomes very amazing. In dogfights u are able to control your speed with much more accuracy. Same goes for flap management in this configuration. In the mock-up I hotglued the pots inside the throttle walls. It got pretty cramped and the idea of an addional,electrics, box came up.
Thats the way to do it IMHO.

Hi guys, thanks for the advice, I'll be starting to build this weekend.

I'll be using Leo Bodnar's controller, http://www.lbodnar.dsl.pipex.com/joystick/index.html, (http://www.lbodnar.dsl.pipex.com/joystick/index.html) which provides 8 axes. I'll be moving over the pots from my trim box, so that's three for trim, then four more for throttle, flaps, prop pitch and mixture. I'm hoping BoB will allow mixture control using a pot, in the meantime I'll assign mixture to a 10-point rotary switch. Not sure what to do with the last axis, maybe it'll be used if I ever get round to building rudder pedals. Now I've got to decide what to assign 32 buttons to!
