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.

Best Servo resolution


Recommended Posts

Wondered if anybody could help me I am trying to find the best servo with the highest resolution because it will be used in a camera focus project - therefore need it to be as sensitive as possible and ideally capable of more than 180 deg of travel

has any body go any suggestions - I was also trying to find out the specs on servo's but wasn't sure which which one specifies the resolution, a friend mentioned it was in 'steps' - obviously the more steps the better the res

As this is now Floobydust, it may be of interest that if you put a 4"/10cm arm on a standard (+/-60 degree) servo, 1 microsecond change in pulse width (usual max resolution of computer transmitters) gives about 1mm of movement at the end of the arm.

Useful for checking 'digital servo', PCM and other equipment; a cheap chinese 'PWM with failsafe' receiver I bought couldn't manage better than ~3mm per step... tut tut!...
