Radio comparisons 2.4 GHZ

I figure if Venom trusts my 2.4G radio so do I ...

You can get real cheap $30 for DIY 2.4Gig kit. Your old radio need s to be PPM, Pulse Position Modulation, like a Futaba FM 3PM.

The Rx's in this kit are 2 wire antenna types. Very nice reviews on RC groups. People fly planes with them.

One of the claimed benefits of the Spektrum DX3S radio is compatibility with their new line of Marine receivers. They claim at least to have made modifications to the receiver to allow better reception in water environments (how, I'm not sure). They also have made their marine receivers water resistant.

Aside from the water resistance, any insight on how the receiver performance could have been improved?

The Dx3 systems are still plagued with range problems. i have used it in my HPI Baja and it stilll goes to failsafe in about 100ft. my friend who has a Warehouse hobby gas boat has the same problem with range. he has since switched to Futaba Faast system.

I like the Airtronics MX-Sport FHSS-2 2.4 GHz Radio w/3 Channel Receiver. You can usually find it on sale at A-Main Hobbies for 80 bucks and it has a range of 1,000 feet on the water (ask me how I know).

We changed the format of the transmission. Marine DSM is very different from Surface (car) DSM. We have range reports from many of our Marine system testers and users exceeding 750' - farther away than you can safely operate your boats. Transmitters with Marine capability have a small boat logo on them. If you don't have the logo, you aren't using a Marine-capable radio.

Also, you need to use a Marine DSM receiver (MR3000) or you will still be limited to Surface DSM mode, which is very low power and only intended for cars. Running a Surface DSM receiver with your Marine-capable radio does NOT give you the range enhancements of Marine DSM.

As in all systems, proper placement of the antenna is essential for best performance. I have witnessed large cars and trucks which had 100' range simply because the receiver was buried deep down in the vehicle, surrounded by lots of metal chassis and engine. Moving the antenna to a better location gave the expected range.

I had the futaba 3pm and loved it. It seems to be much faster than other radios in the price range. I switched to the futaba 4pk and it was not all that much faster than the 3pm. I have never had any problems with futaba receivers or weird glitches or anything.
