LOL NVM, I just thought you were trying to repair it! I was thinking you can get one on amazon for $20 these days. I bought mine to turn it into a collective controller for Black Shark! Good luck with your project.
Thanks.

Also, what Sokol says below...especially where the Aviator and its dodgy calibration issues are concerned.

I'm a little bit sick of the second throttle intermittently restricting itself to half an axis in range mid-flight and getting wandering +-10% all the time on both throttles...thankfully for me it's only been the throttles that have been dodgy, I understand some people have had problems with the X and Y axes.
could I maybe connect up VCC and GND to the spare +5V and -5V pins on the BU0836 board?
Yes, but you get a LED always ON. How this LED work in original Saitek circuit - blink when you press button 2 (SW2)?
I'm not trying to sound like an ass here but I bought my Saitek Aviator for less than a Leo Bodnar board costs. Why didn't you just buy a new stick?
IMO - A new 35 U$ stick dont surpass a MODed one with BU0836.

The LED is on all the time, Sokol.

You wouldn't be able to see it blink when it was under your thumb anyway.
