Hi Vectro,
Im about to embark on the same project. I built Ian motion platform, which works well, not fully tested yet. Had been waiting for his final FFB plans.
Are you buying your motors from Italy and is it being made out of wood?. I will be following your progres with interest.
Regards
Les

OP,

I've been watching his site for a few months waiting for the release of the plans. I downloaded the plans, but will be adapting the concept to the actual Y bar of my 172 fuselage. I'm also going to see if I can adapt this to the rudder pedals. I hope to be purchasing parts for the mechanical linkages later this month. I don't know when the budget will allow for the purchase of the motors or controllers though.

Hi Les,

We are also going to connect the force unit axle directly to the current Y-bar mechanism with this kind of connection:

This way the original Y-axle can move freely. We ordered the controller cards (x2) for the motors last week from Ian and now we are going to order rest of the parts from Italy (encoders and the motors). Our friend have built a CNC cutting machine. With this machine we will cut all force unit frame parts from wood according to .DWG drawings.

The plans and the web page have been updated this month. We will only build this unit for the yoke.

Do you have any additional pictures on your site? I'm having trouble seeing how that linkage works. I had a very different idea but don't have drawings done yet.

I only made this quick drawing about the connection. The basic idea is shown in the cockpit picture. We are going to connect the force unit directly to the rear end on the original C172 control yoke. The original Cessna Y-column remains completely intact.

The movement of the original Y-column is curved but the force unit movement is linear. That's why there needs to be a mechanical joint that connects the force unit and C172 control column. The picture I attached in my previous email is taken from a Frasca Beechcraft Bonanza trainer simulator control column.

Thanks Vectro,
Nice to know i want be the only one building it. Yes i built a small cnc machine a couple of years ago and will be using that to cut the wood.
Will an eye on this post.

Once you are about to cut the wood parts, I can send you the drawings I received from Ian in .dwg format. These should be suitable for your cnc machine also.

Vectro,
Thanks
Have sent you a pm with email address

You've got me re-thinking my design. Using more of Ian's original design as you are may far simplify things. The universal joint positioned where the FFB shaft connects to the 172 yoke answers the issue of angular change between the yoke shaft and the FFB shaft as the y column moves through its arc. How are you allowing for the change in the FFB shaft angle as this occurs back at the FFB chassis? Will you be mounting Ian's FFB chassis on a pivot?
