Hello all,
After selling my 737 project,  I'm now going for a 1 seat GA/Multisim. My aim is not to make it look like a specific model, instead I'll design a Multisim that can be used with a piston or a 737.

So far I've purchased BFF control loading electronics and servo motors, a OEM gear switch, OEM trim wheel, OEM PA34 TQ and  a OEM yoke.

My plan is to use oem on all main controls. Looking to buy rudder pedals and a nice seat in the future.

For flaps control I plan to use a momentary switch so I'm not limited to detents..

The progress will depend much on how much time I have to work on it, so it's a long term project.

I'll start with some pictures of the trim wheel unit.

Trim wheel unit.

Based on BFF trim wheel electronics and an OEM trim wheel from a C150 series.

The unit uses a mechanical linked trim indicator, so no servo och calibration of the indicator. It uses the OEM spirals on the side of the trim wheel.

What's left is the facecard, it's a temporary solution right now. I'm going to a company locally who makes stickers. I hope they can produce something I can use.

Stepper motor with housing, sensing pot and dsub connector.




Module mounted on backplate.




From the front



3d printed front bezel, using hot melt inserts. Works really well. Printed in PLA.



After print, spray filler.





Sanded before filler


Painted!




Look at the difference

I also added a shrink tube around the spring so I got rid of the annoying sound

Really nice work and the shrinktube around the spring is brilliant.  I need to try that.

Hey Steve,
I got the idea of a friend of mine. It was very effective

Work keeps going on. I've done some work on the throttle lever. Designed a pcb and ordered from pcbway, fast cheap and good quality.

I'll use a OEM PA34 TQ, this stand for the pcb will connect to the levers by rods. Mounted on an angle to keep them as linear as possible.

Also been working hard on the parking brake mechanism which turned into a 737 project. I'll make the parking brake like on the 737, I'll also sell this product on my shop. I think its gonna be really good addition to many sims as it work just like in real life. Separate post for that though..

A side project I'm also doing for the Sim are the gauges. I love steam gauges, my plan is to use EADI + EHSI on lcd screens and everything else using steam gagues.

Here's a prototype I'm working on.
