If not I would definately go with either the Futaba 4PK (telemetry), Spektrum DX3S(telemetry) or the DX3R (non telemetry). Especially helpful when setting up a new boat.
Im limiting my budget not more than $200, I've previously bought one 2.4ghz Acoms model, I ask the guy who sell it at ebay and he say it can be use on rc boat, so I bought it and use it, and my boat crash as the signal are not far enough. So the futaba and dx3's, how far can it go?
Stiletto tunnel,EPV135 (53") twin cat, CT06"Spirit of Qatar", FD 47" mono, Twin Mini Cat 23.5"
I have a Spektrum DX3R and both SR3000 and SR3100 receivers. With both setups I have been able to drive my boat from one end of my lake to the other, well over 500' away (it's shaped like an L, making it really hard to judge distance when you're at water level.
The big problem is that you can't see your boat when it's that far away...
Eventhough I do not have it, I read in here in a similar thread "2.4ghz systems" that the 2.4 ghz system provided with the UL-1 is very successful. It is this one:

Its not a problem, its a good thing that u still can control it eventhough it is far away, can it track the top speed w/o the use of gps and does it have a temperature indicator?

For any system in a boat, you can't track the speed without an accurate speed-measuring device such as GPS, lights, or a pitot tube. It's not like a car, where you have near-0 slip (at times), so you can't get it directly from the RPM although RPM can be a great indicator if you have previously determined your slip using one of the other methods in conjunction with RPM. I don't care about absolute speed, just seconds around the oval.
If you use the SPM1305 with an SR3000 you can get telemetry data (RPM, temp, and voltage) with a DX3R. Or use the SR3300T since it has telemetry built-in.
The DX3S has the telemetry integrated into it. I have a 3R because I want my son (pit man) to read the telemetry info. I can't read and drive at the same time.
What exactly are your requirements? We can probably help better if we know what you're trying to accomplish. Why do you want to be driving something you can't see?
Very interesting. I see that the price of the DX3S is not that high for what it offers and cheaper than the DX3R (in ebay). May I ask, you can see the motor's temp and rpm and boat's speed on the screen of the radio (DX3S or DX3r)? How is this done, do you connect any cables on the receiver?
If you have a DX3S, the telemetry data can be shown on the transmitter screen.
If you have a DX3R, the telemetry data is shown on a handheld LCD screen (see SPM1305) that you can mount on your antenna, just like an Eagle Tree Seagull. NOTE: The handheld screen can be used with the 3S also, so you can have a pit man read your data for you.
To sense the temperature, a sensor on a lead is attached to either the SPM1305's interface unit or your SR3500T receiver.
The RPM is sensed by a small opto sensor and band that goes on your output shaft, and connects to another port on the SPM1305 or SR3500T.
There is also a short cable that connects the 1305 to the rx.
There is NO SPEED SENSOR - you need a GPS or an Eagle Tree with pitot tube. You can convert RPM to speed, but it isn't accurate by any means.
Of course, you can get all this info by simply clicking on the link above and getting the manual.
FWIW, I use the SPM1305 with my DX3R when I need telemetry data. Note also that the telemetry link has limited range. If telemetry is real important, especially speed, I recommend getting the Eagle Tree system - it can provide more types of data, it can be loaded into your PC, has much greater range, and graphs can be generated afterwards.
Are you just trying to get the speed of your boat? If so, get a GPS. Are you looking for all kinds of other data including speed? If so, get an Eagle Tree. Are you looking for some data to try out different setups? If so, use the 3S and/or 1305.
There are lots of guys here who can tell you the advantages of one system over the other, but you will get a lot better input if you tell us what you're trying to accomplish.
