Time to help a new young member with some 737 TQ electronics questions?

[Chriiis1]

Hi everyone, I'm Christos, 18, and a new member here.
I would like some help with some questions I have so if you could sacrifise some time for me I would be happy because I don't want to make any misstakes... I dont have all the money in the world.


I have finally decided to make a 737 TQ and my weakness is the electronics.

With a whole lot of reading and studying i have decided to make a nice looking TQ with 5 sliding potentiometers and no buttons, trim wheel or servos so i can have these working :

2x thrusters
1x flap lever
1x spoiler
And 2x linked reversers to a potentiometer
Why? so it can be as simple as possible and of course actually MADE.

Inspiration and what i want to do is approx. the same as Carlos Lopez

My conclusion is :

Number 1

5x http://www.trossenrobotics.com/store/p/3252-Slider-60.aspx
1x http://www.trossenrobotics.com/store/p/5341-InterfaceKit-8-8-8.aspx
5x http://www.trossenrobotics.com/store/p/3260-24-Inch-Sensor-Cable.aspx

The most easiest way but a bit more expensive.


Number 2, more cheeper but harder?

If they work?

and cables which I dont't know how to connect -_-


So what do you guys think? WHICH option and is this really the only things i will need to have the TQ working?

If not, then my question is, what is it that i need to only have these levers (no TOGA buttons, etc) working? (from the electronic point of view)

Thanks for your time and enjoy the beauty of aviation.

Hi Christos,

Easy Project for a beginner, and I can show you how easy it truly is.

Might I save you a lot of time and suggest you go this route.

Fist and foremost this is going to be the easiest, and cheapest method. Register your copy of FSUIPC because it is required anyway.

you can connect 32 switches, and 8 potentiometers to this card, in case you decide to build your own Yoke after your throttle project, you will still be able to add 3 more pots.

To make things easy on you for the reversers.. you can bury one of these in the throttle handles, and have your reverser's bolted to them with a little cam on them that pushed this button when they are lifted. This switch could be programmed through FSUIPC to send the F2 keystroke while held and F3 once when released to engage the reverser's when lifted, and when lowered it will disengage the reverser's.

Just a thought, much easier to implement then a pot for the reverser's.



I am sure you have ebay in Sweden...

Any 50 or 100K slide pots will work. I would suggest getting linear pots, but thats just my theory. Connect your throttle handles to the pots using old metal coat hangers through the bottom of each lever, and you can brace your handles with a through bolt going through all off them at the mid point. Just play around with things and make 3 or 4 models out of scrap until you get the right mixture. Heck if you have any Meccano or Lego use that to play with.

Good Luck

Thanks for your answer! Really appreciated it.

Tottaly got it now! It's leaning towards your option, amazing way and very cheap for me.

Just one question, what kind of wires should i use?

Thanks Trevor
