Hi all


Are there any rules or regulations on what frequency radio gear I can use where?


When I built my boat and used to play with cars it was all 27mHz, My father used to fly aircraft on a 27Mhz, 6 channel Futaba set but I now see there are 14mHz, 40mHz and 2.4Ghz sets. 27mHz now seems to be a thing of the past?


Are there any rules of what you can use where, Can I still sail with 27Mhz and what are the advantages of the various systems.
I have a lovely 6 channel Futaba 40mHz set that I was going to build into my next boat but don't want to be turned away at club waters for having the wrong frequency gear.


Cheers

27 and 40mhz are for land and water based
35mhz for aircraft
2.4Ghz can be used anywhere

27Mhz is not dead, although given the cost of sets and the simplicity for above water models, 2.4 Ghz takes a lot of beating. 27 Mhz channels were split yet again a few years ago, although I am not too sure if there is any equipment available to use the new channels.


There is a web site that gives details of UK Radio Control regulations http://www.ukrcc.org

Thanks all and thanks for the link Barrie, I'll have a read.


Looked at my nice, hardly used 6 channel set and it's a 35Mhz Skysport 6 set. Guess I can't use that in my next boat then.

The link to OFCOM's information sheet on radio controlled models on the UKRCC page is out of date, the document is now at -

Thanks Steve


That confirms that my 35MHz set is for air only, Wonder what you do if you build a flying boat model or a seaplane? 


I assume you can't simply stick a set of 27 or 40MHz crystals in a 35MHz set to change the frequency?

Much cheaper to buy a 2.4GHz converter to turn the (formerly) 35MHz set-up to 2.4GHz.

They're out there, and cheap. You'll need to solder a bit, though.

If it's a module based set you would change the module.

If you are up to it, you might be able to convert to FrSky 2.4GHz using this -

35MHz or (most likey these days) 2.4GHz.

Beat me to it....

Down here in Oz. we can use 27 Meg. Channels 1 to 12; 29 Meg. Even channels 10 to 36; 36 meg. channels 601 to 659, odd channels only, even are reserved for flying. 40 Meg. channels 67 to 92, odd channels only, even are reserved for flying. Plus 2.4 Gig.
27 meg. was banned for a while whilst CB was popular but is now back.
Has not got through to the flyboys yet.  At a recent event where there were boats and planes, all the planes on 36 Meg. were on boat frequencies.  fortunatly there were no 36 Meg. boats.

A few years back, if you built a seaplane model that was a "boat" only, it had to be on 27 or 40mhz, as soon as that model became a flyable "aircraft"that actually flew it had to legally be on 35mhz, but since the advent of 2.4ghz it now does not matter.

Thanks for the advice everyone.


Decided to go with a conversion kit on my existing radio gear so now have a Skysport 6 on 2.4Ghz. 


I used a kit from Giantshark made by Corona which was easy to install and works great but I found out that you need to watch out for different standards. My transmitter is something called DSSS and the first receiver I bought was an FHSS standard. Once I bought another 6ch receiver with a DSSS standard it all worked as planned.

One question though, Am I now limited to using Corona receivers or will other brands be compatible? Looking at the instructions they seem to say use only these Corona products and looking on ebay at other receivers they say only compatible with their own make transmitters but I kind of thought there would be a standard so other receivers would work with other brand transmitters?

If anyone needs an 8 channel Corona FHSS receiver, never used, let me know.
