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.

Anyone have any experience with the brand name "BaDa"? They make several 2.4ghz transmitters ranging from 500mw to this one that claims 3.5W. I noticed that the power consumption is very high on some, for example the 2W version's documentation seems to say it uses 3000mw of power at 12V.

There are several also on ebay ranging from $50-$60USD.

Generally speaking, I usually find that input power consumption is usually about 4X to 6X the RF's power rating. So a 3.5W (RF) rated model might become a very toasty warm Tx.

It is wise to be cautious about advertised "power" specs. There's a lot of funny numbers being published and so you can't always believe the stated watts. Many times these numbers are total fantasy (offshore eBay sellers are notorious for this). Also, in my opinion the Tx's RF power is often less important than the Rx's performance (sensitivity and selectivity). There's a lot of imported Rx's that have a hard time providing good range, even with a high powered Tx screaming at them.

So, trying the unknown A/V system brands can be a bit risky. But sometimes a gem is found. For example, all the popular and good performing systems being used by us today are due to the risk takers. Through trial and error, they picked through an endless number of systems to find those that consistently worked best. Those that have been on this forum for a long time know all about it, since just about all the popular systems sold today were identified by their efforts. :)
