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.



500mw transmitter fried

Voltage regulator, most likely.

Are you sure you didn't reverse polarity/have wrong voltage?

was using a 3 cell lipo so should have been good, checked polarity when I heard it crackle but it was around the right way. I had been flying in the morning with it and decided to change from funjet to a glider so I powered the vid transmitter up to warm up the casing to melt the hot glue a bit without camera attached but with aerial and it is now toasted. i dont know why it fried, I presumed from no video signal but I thought I had done this before. I have ordered another one but would like to fix this one if possible. Thanks for replying

A typical VReg IC rarely does that unless reverse voltage was applied. Are you sure the battery leads are correct? Check again.

BTW, it is probably a 7808. If you cannot read the smoked part number then it would be best to check with a working Tx to confirm the part number.
