Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This was announced several months ago (March 2021) to allow our members ample time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

Is there a way to make the servo tester work with 1.9k pots instead of the 5k pots?

I am wanting to use the tester with a FrSky replacement gimbal PR10.

1.9k is what I measured , but the box states resistance range is 2.4k ohm.

Sorry, I wanted to put this under Rc-Cam Projects

You might achieve satisfactory results by altering cap C1's value. Currently it is 0.1uF, but try 0.22uF.

I suggest using an o-scope (or servo pulse tester) to confirm the pulse width values. If necessary, vary C1 and/or R2 until you achieve the desired pulse width range.
