Author Topic: CH Pedals and replacing pots = PROBLEM! (Read 515 times)

I have some CH pedals, not the pro's, just the basic ones. Ive had them for about 2 yrs now, and the pots are wearing out, so i ordered some new ones off the web from the CH store. Great stuff i thought.

I opened up the pedals and swithed the pots over and now i cant recalibrate it. There is a little cog that fits over the end of the pot which locks into some gears on the base plate, so you can adjust where the cogs mesh and thus their resting positions. I have tried all posible combinations and have not had anything that comes close to being correct once calibration has been attempted in the control panel.

Does anyone know much about these pedals, or had experience with this sort of thing? Im a bit of a bunny when it comes to electronics so i dont really know what im doing.

It seemed easy...

HELP!!!

it looks like you would want to center the pot at 50% of its travel and center your gears when the pedals are at detent and hook them up to your pots so that full travel up would use 50% of the resistance and full travel down would use the other 50% of resistance. Do this for both sides and it should work I would think but hard to tell just lookin at a picture!

yer, but the gears on the pots will only mesh onto the base plate gears at certain places, ones which are not an even 50-50 split.

OH, and btw , there are two pots 100k each, one in each pedal.

ok I have the USB Pro Pedals, as a pedal is pushed forward the other pedal goes backward do yours do the same or do you push the pedal down to get rudder deflection?

Did you happen to notice if your old pots said HP-100 or HP-106?

No they dont slide like the pros, just rock.

the old, and the new, pots have 900-630 9607 R0C on them.

Ok yours are pivots then, so the pots have to be turned to the end of their travel, opposite of the way the gear on the pedal is going to make them move, maybe 1 toothe engaged maybe two so that at the end of the pedals trave the pot has turned as far as its going to, have no idea how many turn pots they are.

Make sure you have soldered up the wires the same way they came off, and if the right hand or left hand lug was soldered to the center lug on the old pots that will need to be done to the new ones as well, when soldering make sure not to have the pedals connected to your system, if you have an old soldering iron or gun you could induce a voltage into your system from the tip of the gun.

Dont know about "normal" pedals but the pro version is a squeak to put back together. I cleaned the pots once on mine - I don't want to do it again;)
