Hi Daisy,
still no answer from UIV?
I'm sorry for delay of answer. Because now it's hot time for production. Launch of the new joysticks (Gladiator, Mamba, Gunfighter...) takes a lot of time.
Now I will give you detailed answer. English is not my native language, but I'll try to be understandable.
1) About gap.
This two arm of pedals are fixed by ball bearing unit, which inside are with two ball bearing. Now I try to explain you about tolerance, it's engineering topic and not easy for explanation, but i try. Inside ball bearing are balls, ball bearing manufacturer make gap between ball and ball ring so that to prevent deformation from heating. As when ball bearing moves with high speed, it can cause heat. Finally inside and outside ring have tolerance in angle. Only cylindrical ball bearing can be without any angle, but they are with big size which can't be used in this place. So tolerance from axis, from ball bearing unit and teeth washer can make unit go with angle. All this tolerance plus minus can cause some angle. Of course some pedals can be without angle when this plus minus tolerance offset. unit work in assignment. For example, tolerance in angle with 1.5 degree can cause misalignment of arm, which can't be noticed. But unit for feet is long so that you can see angle.
But sensor measure angle from CAM, not from arm, so that angle from arm have no influence in function and precision. Besides, when you push this arm with feet, your feet can cause angle of arm. But you can't feel this angle with big force. And you can press pedals after calibration, you control full range of pedals, which will not break any good control of pedal. You can test its precision from vkbjoytester software and check how it works.
2) About sound.
We are grateful for this information, we will pay more attention to this unit and make changes in our next model. Thanks
3) About CAM
The screw with metal parts is used for adjusting force when clients want to change position CAM. Since CAM gets big force from spring. With this construction, it can reduce force from spring.
The destroy part which you show on CAM, it's not destroy from CAM, but destroy of chrome coating on CAM. Ball bearing moves on the CAM with so big force that can destroy any covering on metal. But CAM is made from strong steel ( carbon steel grade 45l), which can't be destroyed. While thickness of covering is only around one thousandth mm. CAM part we especially design inside of pedal which can't be seen.
Some clients whose environment with big humidity (for example tropical), we will recommend them to use some grease to prevent rust. We don't add grease from factory because when some clients try to change CAM, grease can cause dirty.
4) Do not worry about quality of VKB products. We born and live with high quality. I'd like to show you our first pedals which was 10 years ago.
One of our clients bought it 10 years ago and recently he bought our T-Rudder pedal again. This pedals is still working perfectly. Yes, after 10 years, surface of some metal parts cause damage, but contactless solution and construction from metal can work many many years. Ten years later, pedals look like old pedals, but continue to work as new ones.
