HelicopterRadio - Spektrum DSM › Clarification needed on power output and signal security of toy mcx transmitters vs DX6, 7 etc...

I know there are alot of very knowledgeable people here so I will put it simple. To be decent I will not name names.

I have a discussion between some individuals who are convinced that a toy MCX radio is that exact of the technology of say a DX6,7,9

Perhaps they are rooted from the same base product, however it is clear to me in owning several of the small gym flyers, such as a mini CX, MCX, parkzone sukhoi plane and more that to me these radios are not the same.

In regards to power output, my DX7 can output more range but at least 10 times more then any one of my MCX, Sukhoi etc transmitters. Others agree and see this as well?

To me it seems the toy transmitters also are not somehow secure, I assume they may not do any signal switching or have the same level of channel security as the DX7 etc. Anyone else notice this and agree? It has been said some MCX transmitters and others have been sucseptable to interference from common 2.4 phones, never once have I heard or seen of any Spektrum tx,rx get intereference from a phone...

I have been looking for some hard data on the toy radios that would show some concrete number differences to sort out and educate some people that expect and feel their MCX radios are up to par with DX7 etc, and to me they are simply not.

Anyone has some links or knowledge of getting some direct comparisons that woudl be greatly appreciated. Thank you.

Anyone? There has to be some sort of comparison out there on this?

Reduced power - I suspect that you are right on that point. They are deigned specifically for park flyer and indoor. No need for the range that is required for a DX7.

Reduced number of channels - The mCX only needs 4 channels and that is all there are. The full size Tx support the number of channels you require for a true heli.

Technology - I fly my mCX with my 9303, so the technology is the same. The same security from interference from other flyers.

You asked for:

I suspect this is why you have not received much feedback. No one really expects the little Tx in these "toys" to be up to the capability of the better radios. Heck, you can't even program Expo, let alone anything else you need for a real heli. In the mCX the mixing is done in the 5 in 1 board in the heli, not in the Tx. So, I would be surprised if there were such a comparison.

Yes but how much difference is what I'm after, as well I believe there is in fact some differences on it's ability for hopping etc..as some have claimed that their 2.4 phone has interfered with their mcx helis etc, never ever seen a DX7 with Spektrum rx etc have this issue ever...

The FCC has a site where RF specs can be retrieved for certified transmitters. It may be possible for this information to be found there. (if the need is great enough)

Gravity is what makes flying so much fun!

The DSM system does not frequency hop. When the Tx is powered on, it picks 2 channels that are not in use by another DSM system. Then when the receiver is powered on, it looks for the system with the unique ID that was established at bind time. For the rest of the flight, the Tx and Rx remain on those 2 channels.
