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.



How to improve range between controller and plane


Recommended Posts

Antennas, antennas, antennas. A better receiving antenna for a video link if that's what you're talking about.

A good Tx and RX and noise suppression in the planes equipment & wiring, if that's what you're talking about.

I was actually talking about between the remote (futaba) and the plane. Any answers will be greatly appreciated

OK. The RC system. There's not too much that can be done about range except to keep the Rx and Rx antenna away from the other wires in the plane as much as possible to lessen "noise" pickup from the motor and servos which can "desensitize" the Rx resulting in decreased range. Since it's "line of sight" frequencies, you'll probably lose sight of the plane before you lose control unless you're FPVing. For most brands, I have heard 1000 or a bit more meters mentioned for max range (still line of sight) before loss of control. The only antenna that can be modified (if you have the proper measuring equipment) would be the Rx antenna as nothing can (by law) be modified on the Tx.

The only alternative would be the Amateur Radio Bands where one can build or modify equipment as wanted for an increase in range.

As Ron says, noise from your own plane it the main range killer.

I keep the aerial well away from everything, use an opto coupler for the receiver outputs and use a separate battery just to power the receiver.

Interesting - link to UK supplier?

This is the only one I know of http://www.smservices.net/acatalog/Large_Model_Units.html

but there are a few circuits on the forums I have seen if you don't mind building one.

Mine is built into my UHF receiver so I don't use any of the add on units.

Waht UHF system are you using with the optocouplers?

It's my own design based on 458Mhz modules retuned to 459Mhz for UK use only, it's about the only thing that is an advantage in the UK :P
