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 is being announced now (March 2021) so that everyone has 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.

  1. First number: 5 or 7.4 or 9 (depending on the setup I'll make) Second number: - If I calculate resistor for EACH set (4 resistors total before the parallel connection) then (adding the numbers as "note 1" says) then 10.4 (3.2 x 2 + 1.9 x 2 the first 3mm red found in the list) - If I calculate a single resistor for the whole setup, even worse, 41.6. Third number: 20 (a typical current) ...boom... "Try Again! The source voltage must be a bit higher than the forward voltage." So according to this, a 5V can power a... single white LED with a bit of voltage to spare. (
  2. Well tried to use that calc, but seems if I add the (supposed) Vf I am well over the allowed numbers (whether I use 5V source, 7.4V or 9V). Must be doing something wrong.
  3. Thanks, sounds like a plan. So, not bother with direct-to-battery (main or dedicated), not bother with resistors?
  4. Hello and I hope for warm welcome (read: with helpful replies :D). The car in question is a FEIYUE FY06 (google it). It has a 7.4V 2S battery 3000mAh. Has two empty connectors on the ESC (35A). It has space for 4 x 5mm LED on top 2+2 x 5mm LED in front 3+3 x 3mm LED in the back So I got four (4!) of these sets: http://www.ebay.com/itm/4-LED-Light-Set-Headlight-Headlamp-Taillight-for-HSP-1-10-RC-Car-Truck-Crawler/152493354026 Note white are 5mm and red are 3mm like I need... so with four sets I fill all positions and have 2 red to spare (probably put inside the cabin somew
