Radio Gear Stuff

In this section there will from time to time be info on what is happening in the world of radio control systems that are used to control the models. 


I will kick off this section with just some simple comments on what I have recently been trying.

Earlier this year I took a calculated risk and bought a couple of JR synthesised receivers to use with my Hitec Optic 6 and Hitec Eclipse 7 transmitters equipped with Spectra modules to try out and see if they really did make life at the poolside easier by eliminating channel conflicts. To date they have worked very well with no range or control issues.

I had some, probably unfounded, misgivings about having to pull the Spectra module out of the TX each time I wanted to change a frequency. I felt, that long term, the constant removal and refitting of the module in the TX's would make the connections faulty. 

Enter the Multiplex Cockpit SX fully synthesized radio system. This is an elegant radio both in operation and design. No modules to remove and refit in order to change frequency. Just press a dial and select the frequency you want. Then just tune the receiver to the selected frequency. It is also the only FM TX that I have never had to pull apart in order to remove the left sail trim stick self-centering operation. Just an adjustable screw accessible from outside the back of the case does the trick. No springs to remove using only clumsy fingers, tweezers, long nosed pliers, etc., etc. It is slimmer in design than either of the two radio's mentioned earlier, making it easier to hold. It is simply elegant. Almost a work of art one might say. I do love beautiful things.

But what I really pined for was a Spektrum 2.4Ghz system. I had stayed away from the DX3 and then the DX6 radio's because I had concerns about range. Then the Spektrum DX7 came along promising that range was to the limits of one's vision. Well, I had to try that one, didn't I, and I bought what must have been one of the first units in this country. It works a treat, and is as far as I can tell equal in range to all the 36Mhz FM radio sets I have used. And with the knowledge that I don't even need to select a free frequency, no matter how easily I can now do that, there is a lot going for the DX7. It is also equivalent to a fully synthesised system although it works differently to the 36Mhz stuff.

There is a difference though between synthesised 36Mhz radio's and the Spectrum system. Something that FM still has going for it despite what Spektrum has to offer. Both systems have their strong points and their weaknesses when compared to each other.

Stay tuned for further comments/thoughts soon. On second thoughts, please just visit the Forum where further experiences/comments/thoughts will be discussed.
