A beginner question
I am not sure if this is answered any were but i am going to ask anyway.
My plan was to remote control my boat. and i got a strong DC engine in it so i need to use a some kind of relay (I have fund one i think i am going to use DoubleSwitch)
And my first plan was to youse a normal FM 35mhz transmiter i got from my first heli. But then i saw a cool helicoper i am also is planing to buy:<meta http-equiv="CONTENT-TYPE" content="text/html; charset=utf-8"><title></title><meta name="GENERATOR" content="OpenOffice.org 3.1 (Win32)"><style type="text/css"> </style>

And that one includes a 2.4ghz transmitter, and after reading a litte about it i figure out i could instead putt a 2.4 reciver in my boat, and use the WK-2801 pro transmiter.
But then a friend comes over and i tell him about my plan he says i must youse a reciver off the same brand as the transmitter so my plan to use a:<meta http-equiv="CONTENT-TYPE" content="text/html; charset=utf-8"><title></title><meta name="GENERATOR" content="OpenOffice.org 3.1 (Win32)"><style type="text/css"> </style></meta></meta>
EK2-0424 E-sky reciver is shatered.
So my question is that he says true... so I must to use a walkera reciver also.
And can i use the WK-2801 transmitter to controll a boat???
Mmmm... This is the longes thing i have writen on a forum
Sorry for the spelling errors :P

I'm not sure what your frenqency allocation is over in Norway, but here in the U.S. we use different freqencies for air and land/water use, that radio thats in ebay is only for air use only.
Its a safety thing, that way there are no interference with the radio signal causing a malfunction.
As long as the reciever & transmitter are of the same freqency, you may mix different brands...
Technically, any radio will work, but in most countries 35MHz is reserved for air use and must not be used on anything else. 27MHz is fairly universally for anything, in Europe 40MHz is for surface use. 72 and 75MHz are used in the US and neighbours. 2.4GHz is the coming thing, only needing the RX to be "bound" to the TX, no crystals to worry about, no worries about interference with other users. Different makers have different ideas about protocols, so its best to stick to a single manufacturer. The only downside is that 2.4GHz doesn't work in submarines.
I think i am going to stick to my plan and use this: www.dimensionengineering.com/DoubleSwitch.htm it is maby a little to weak but it might be enught

and here is a link for all frequencies allocated for the world, just pick where your at:

Compared to the switcher in your link, not a huge increase. There are lower price devices available if you look, removing the need to drive in Schumacher mode, but leaving the ability to do so if you really want to.
