Best way to eliminate spiking


Recommended Posts

My 737 rudder pedals (right toe brake) is spiking. When i calibrate them in windows you can see the red bar twitching up and down slightly and the right toe brake numbers are totally different so not quite sure what went wrong in the factory!

So what is the best way to eliminate this problem? I have also contacted the company for now.

Note sure why you are asking here -- you really need a hardware forum. However, here's what I (think I) know:

Lots of such devices "wobble" a bit. They are usually based on a potentiometer -- a sliding contact on a resistive material so varying the resistance. This is then usually measured by timing a capacitor discharge through that resistance (or at least that's how it used to be done). Lots of things can interfere and give less than precisely fixed values: dirt, temperature variation, humidity, and voltages. 

When assigned in either FS or FSUIPC small variations are normally ignored. FSUIPC even allows you to set the threshold for this, which can be increased if necessary. It does have a spike removal option as well, but that's for extreme spikes to one end or the other, usually caused by bad connections or missing bits of the resistive surface.

Can't figure out why both brake values are different

The point of calibration is to eliminate differences in the end result.

Where is the spike removal option?

You are asking about FSUIPC now? As documented, that's in the Miscellaneous options. But that's only for spikes t max or min, not wobbles as you described.
