Logitech G27 with Momo Prototipo – Custom built

This customization was made using a Momo Prototipo my father had on his Renault 5; “Perfect combination for my wheel”, i thought.

We have here a stock  G27, with a chilicoke style adapter for 70mm pcd wheels, a Momo Prototipo, 310mm and NKK push buttons.

The MOMO: This one is from January 1980.

Logitech G27 Base

It might be a misuse of a wheel on such base and i agree. There was one on eBay  that was sold 1000$.

You can game on a 300$ computer, but is not the same as gaming on a 1000$ computer… . The same with the wheels: you can drive in a game with a 300$ wheel, but it is not the same as driving the same game with a 1000$ wheel…

So is the question; “what are we looking for?”

• I want to push and pull as hard as i can, i want it to go through 60 laps at Nurburgring  and maintain the same exact force feedback from the start lane and this wheel is not for this base. Maybe a Fanatec CSW or a direct drive.

• I want to turn it and not be worried about braking something,

• I want to feel the bumps on the road and be able to prevent and predict where the car will be and it can´t be done with the Logitech G27 base wheel; i will redirect to the post about the base.

This Momo does not impact the force feedback output much.

The default logitech wheel is 270mm and the MOMO 310mm.

NKK Push buttons are high quality push buttons, with a precise feel when one triggers them. I had several available choices regarding buttons and from 2 brands (Knitter & NKK) i stood with the NKK for a simple reason; i eventually found a supplier that could sell them. These push buttons are not easy to get in Portugal and i could not find them at all. The big European suppliers do not sell  small quantities or for domiciliary use, but i could find one; Mouser Electronics.

To give an idea:

1 NKK Push button: 4€. (Image above)

1 Knitter Push button: 7€ ( Credits to Leo Bodnar for the Photo)

1 OTTO pushbutton : 15€

These OTTO buttons are a must and surely will use them in a future project. Anyway, they will stay amazing on a decent wheel.

A good part of GT3 cars in the “real world” make use of such push buttons and switches on the wheel´s car and interior.

I need to make a distinction regarding the push buttons;

Although NKK have a precise feel they are not for everyone. They require a bit of force to actuate ( MB2011) and this is where the Knitter push buttons are strong. They seem much smoother, with a not so strong click, but with a precise, high quality feel.

NKK modular push buttons:

G13B Guard (Aluminum / black)

The wheel was fitted with a NKK G13B Guard and yellow caps. There is a whole array of caps,  guards and nuts for the push buttons. Bellow is the G12B guard, in aluminum too, fitted with a 8mm yellow cap.

All these extra parts are paid, so the caps, the nuts and so on.

What is seen on image #1 is something like 20-25€..but it is worth it. The buttons are almost all in metal and there is the possibility of connect them in “normally open” or “normally closed” way.

In a nutshell:

“open” or “closed” refers to a circuit that electricity goes by.

“normally open” is when electricity cannot go through because the circuit is open, hence the button is not connected. When the button is pressed electricity can go because pressing physically the button closes the circuit.

“normally closed” is when electricity is always going through, so the button is connected and giving an input. If you press it it stops that input. It is the contrary of the function above.

The caps are “screw down” caps, and they are interchangeable. Can be used on different buttons or on the same buttons, different sizes.

I have opted for just 3 buttons on the wheel itself. Two of them to look to the sides and one for radio. This was a rational option, to make the wheel with less “gadgetry” possible but having 2 or 3 basic functions.

In the tone of summing up…

It is wise to be said that i enjoy the experience of driving with this custom logitech g27 and that i have learned two or three things;

• The Logitech G27 base is a decent base (highly customizable).

• The Momo Prototipo is rare, with decent size and very nice spongy feel to it, when you really grab it!

• NKK push buttons feel is great. High quality click, modular and robust.

In the world of tomorrow, i will certainly fit this wheel on a more reliable and manly base, something that can provide me a good  experience .  I mind the quality of my experience, when driving; if i do not mind it is because i can´t afford it!

Ultimately we just need to go and get the pieces to allow ourselves the experience, a good quality experience.

See ya soon.
