I'm not even sure how to get the case open, if I can figure that out I can probably get them to turn where I need them.

four screws on the bottom.

just know you are opening up a can of worms here... if you can't solder and are not comfortable with this stuff I DON'T recommend it.

If you want to send it to me I can see what I can do to fix it for you.

I took it apart to look, no way I can solder that. Really a bummer

send it back to them, they will fix it for free but you need to pay shipping to them.

I just emailed Fyetech... really sucks, I bought it 2 months ago, took a month to get to US from China, my FPV plane crashed and was taken because of an RC link failure 2 days before it arrived, it finally got returned to me just 2 days ago, and now it's going to be 2 more months to send it to china and wait to come back...

everything I order from china is here in less than a week... can't imagine how it took that long.

however now yes it is expensive to send back and also will take about a month to send and get it back from them... at most..

and honestly I just can't belive those pots are stuck and one is stripped? did you strip the one?

i would have to get the part number and order from digikey then I can replace them for you no problem but maybe someone in your area can help you?

Almost everything I order from China takes around 3 weeks... at either rate 2 pots are stripped, I know I was the one that did it, I didn't even realize it, I just stuck my flat head in and went to turn and instead of turning it stripped it out on both elevator and rudder.

oh yeah I can't gurantee you anything BTW... I don't know the history on your unit and also may have a heart attack while soldering and destroy your board

man that is so strange....

ok up to you the offer is there, I will do it for free but you pay parts and shipping.

parts will be less than a dollar each but shipping to my place is 7$ from digikey. however I need to get ahold of FY to get the numbers on those pots as they will be in a specific resistance range for the AP.

then you need to pay shipping to me and back...

all that being said if you know someone good with a soldering iron they can do this for you...

I don't even see how it COULD be soldiered, looks like a multilayered PCB.

you can't see the back of it? can you take a picture front and back for me?

I have replaced the processor on boards just like that with sucess before a pot should be childs play comparitively.

I would have to de-case it again... but from the bottom side opposite the pots I saw a row of resistors... definitely beyond my skill for sure. I wonder how well it would function without rudder...

i will function fine without rudder... you can use it on a wing but you need to be able to adjust the gains.

Well aileron adjusts just fine, which is the most important at least...
