Never read them as I wasn't thinking of a new radio, but saw threads on the R/C car chat rooms where they were having problems with the Spectrum radios and people were giving up on them. Maybe they got the bugs out by now. My .02 Ralf

Ralf 13,

What were the dates of the posts in the car forums, and when did they buy them. Most new electronic devices end up showing some issues once they get in the hands of the public. We tend to subject them to situations that were not tested in the lab.

[Ralf 13]

This past summer, they were having glitching problems. As I said I didn't really pay much attention to them as I wasn'tr thinking of a new radio at the time. Ralf

[tracer]

It was glitching due to Flourescent lights in some indoor race tracks. That problem was fixed free of charge for some of the earlier units.

My local indoor track now is 90% Spektrum.

I'm actually looking at this radio for my first air radio.

Does anybody know a good USB adapter for JR radios? As I would be buying this to fly sims for a while before getting my first plane.

Don't most home phone, wireless routers, and microwaves run on the 2.4 Ghz frequency?? Just wandering if this would affect reception.

Did'nt you read the link??? It said "No interferance technogoly"

Spread Spectrum - Perhaps the perfect solution for park flyer pilots

In the old days, when glow planes were king and you had to spend a long time building your plane, you almost had to have the help of a club and the use of a club field. Enter the small electrics, often called park flyers. The smaller, quieter nature of these planes means that they can be flown in more places without drawing attention. People are flying them in parks, school yards and some of the slow flyers can even be flown in front yards and in school gyms. And, because they are inexpensive and easy to buy and fly, people are teaching themselves to fly. If you crash the plane, some will just bounce, and many of the others are easy to fix with good parts availability. For relatively little time and money expense, you can replace the whole plane. What could be bad about this?


THE PROBLEM - Channel Conflict on 72 and 27 MHz

One of the concerns of the RC flying community is that people flying off the club fields are not being taught about frequency control within the 72 MHz RC airplane hobby band. The feeling is that these off field flyers are beginning to represent a danger to the safety of planes and people on and off the club fields. If you are flying your RC plane at some school yard you could interfere with those on the club fields or with other parkflyer pilots elsewhere. You could be causing crashes and not even know it. Or you could be subject to loss of control of your plane and not know why.

The issue is channel conflict. The AMA recommends that club fields be at least 3 miles apart for this reason. At the club fields, channel conflict has been handled by frequency control procedures. But, with the dawn of the low cost park flyers, many new pilots are not members of clubs and are flying outside of the frequency control procedures of the clubs.

Some pilots, using 27 MHz radios rather than the traditional 72 mhz radios, may feel they are not at issue, however more and more of the 27 MHz RTF planes are being flown on club fields. Also, 27 MHz is also used by RC cars and boats. Someone running an RC car on the other side of the park could easily turn your plane into an out of control missile or, at least, turn it into a pile of junk. So 27 MHz carries its own problems. What to do?

A NEW RADIO THAT AVOIDS CHANNEL CONFLICT - Spektrum DX6 Spread Spectrum 2.4 GHz Park Flyer Radio

This technology was introduced to the RC car community a while ago. Now available for RC airplanes in the parkflyer class, it does not interfere with, nor is it affected by the 72 MHz or 27 MHz radios in common use for airplanes today. In fact, by design, 2.4 GHz devices of all kinds are made to work around each other without conflict. No channel control is required as it is designed right into the specifications of the radio. It is totally automatic!

This means there is a new 6 channel computer radio choice that may be the best of all worlds for use by parkflyer pilots. When you compare it to entry level 6 channel computer radios like the Futaba 6EXAS or the Airtronics VG 6000, it is quite competitive in price and features. And since the radio is targeted at the parkflyer community, it is packaged with 4 micro servos and a micro receiver that are very appropriate for these planes.

Note that it does not have the range for larger planes nor is it recommended for glow planes or larger gliders. Not statement is made by the manufacturere, but based on field reports by users who have tested it to its limits, practical range for this radio seems to be about 2000 feet. Would that range be enough for your "parkflyer"? How far out can these planes be flown, from a practical point of view.

This pilot put a GPS into his 60" Phoenix Raninbow and flew it out as far as he
dared.
http://www.wattflyer.com/forums/showthread.php?t=4020 post 16

His report says he flew out about 490 meters, or about 1600 feet and to an
altitude of about 550 meters, or about 1800 feet. So a 60 inch electric or
glider should be a very very good match for this radio.

If you are considering an entry level 6 channel computer radio, add this one to the list of radios you consider.

I have been using my DX6 for a while now and I have two receivers. It has been flawless in operation. Not a single glitch or problem at all.

I have flown with it waaaaay beyond the range the advertise it for and it has been rock solid.

I am not aware of an advertised range. Where did you see a range stated by the MFG? I would like to see that.
