J.C. Cone Posted March 24, 2007 Share Posted March 24, 2007 Returning to R/C after 20 yearsI will be buying a new radio soon (6-7 channel)These new 2.4 GHZ radios look to me like the best way to go. I'm not sure if I should get the Spektrum or wait for the new Futaba.Suggestions and opinions welcome.ThanksJCNever run out of altitude, airspeed, and ideas at the same time.

Tim Mackey Posted March 25, 2007 Share Posted March 25, 2007 One thing to watch out for is that all the module system units so far, have NOT got all the features of the dedicated SpektrumDX7 DSM2 system such as model match, and servo synch. However, I would expect the full 2.4Ghz system that JR and Futaba are almost certainly going to release eventually ( they better get a move on )will have equal specs, and probably more channels as well. Whichever you decide to do, it will require a change of all your receivers of course...so as stated above, expect a flood of 35 meg stuff on the s/h market.

Capt Kremen Posted March 25, 2007 Share Posted March 25, 2007 Check this link - more 2.4 gear on its way perhaps soon?http://www.xtremepowersystems.net/Dissapointed with RCM&E report on the Spektrum. Where were the pictures showing EXACTLY how the gear was installed in the Magister and Mr Wilshere's valuable collection, and how to orientate those twin Rx units and their aerials etc Hmmm????? (We've already seen hundreds of pictures of Magisters in the air!) Quote Link to comment Share on other sites More sharing options...
Essjay Posted March 25, 2007 Share Posted March 25, 2007 These guys (XtremePower) have been promising for months now and are taking so long, I'm afraid the other players have beaten them to it. I agree with Timbo that perhaps modules are not necessarily the best way to go to get the "full nine yards". I'm happy with my DX7 and will wait (as I said before) for the big players to bring out 'high spec' dedicated 2.4gHZ sets. Quote Link to comment Share on other sites More sharing options...
Capt Kremen Posted March 25, 2007 Share Posted March 25, 2007 Thanks SteveJ.How do find installation of your DX7?Is it critical to orientation and location?RCM&E and the other 'comics' aren't showing this detail, they all gloss over this.Hope Multiplex (my current radio) can catch up soon but perhaps they've invested too much in the EVO and SX of late to abandon in favour of another system.

Essjay Posted March 25, 2007 Share Posted March 25, 2007 Hi Capt,No problems with installation at all, however I think the manual could be a little 'lacking' for a complete beginner. For instance, if using 2 servos in 'flapperon' configuration, the diagram in the manual shows connection of right aileron servo to AILE receiver port and left to AUX1 port, and the manual says ' Neutral adjustments of each servo are made bt the Sub-Trim function'.That's no problem if you know that AUX1 now becomes FLAP in the transmitter menu, and unless you have inhibited the flaps in the menu, you will get some "strange" movements.To be fair, this is pretty common to most radio sets, but as I say it can be confusing for the newbie.

Tim Mackey Posted March 25, 2007 Share Posted March 25, 2007 Aerial orientation is straightforward enough. The main receiver case is normally mounted in the fuselage lengthwise -putting the aerials ( approx 1" each protudes at either side of the case ) "across the fuselage". The other smaller satellite receiver ( with similar aerial wires)is then positiond a few inches away with the antennas either vertically, or at right angles to the main IE lengthwise to the fus sides.I have now fitted the system to 4 aeroplanes, and in each case receiver mounting has been a doddle, and utilizes both of the scenarios above. My smallest ALFA sabre EDF has been completely cured of all glitching, even using a cheap tower pro ESC, and both receivers and their aerials are completely enclosed within the mettalic painted fuselage.I can fly this, and my other models to a great range, virtually out of site, with absolutely no problems experienced whatsoever. If you like, I can post some pictures for you to see the installation. Quote Link to comment Share on other sites More sharing options...

Andrew West Posted March 27, 2007 Share Posted March 27, 2007 HiI will also be returning to R/C after a 11 year break (kids!!!) Looking forward to seing these new 2.4GHz systems. At present it looks like the Spektrum has the edge but if Futaba take much longer getting it 'out there' then they will miss many sales as the decent weather is on it's way. I have always bought nothing but Futaba and have never had any problems with anything i bought. Could be time for a change!! Quote Link to comment Share on other sites More sharing options...

John Neale Posted April 2, 2007 Share Posted April 2, 2007 +Hi EricI've got a Reftec tx and rx in excellent condition. I haven't used it in ages due to the rx size. I also have some spare xtals. All are surplus as I can't see me using it again. Reckon 2.4 is the way to go eventually. Quote Link to comment Share on other sites More sharing options...

Mike Johnson Posted April 7, 2007 Share Posted April 7, 2007 Futaba have just announced the T12 FGA 2.4Ghtz 12 Channel set, that should put the feline amoungst the avians.Mike Quote Link to comment Share on other sites More sharing options...
John Cole Posted May 8, 2007 Share Posted May 8, 2007 If you look at www.futaba.com you'll see that Futaba have announced in USA 12, 7, 6 and 3-channel 2.4 GHz sets, plus 14, 8, 7 and 3 channel TX module/RX combos. The site shows the applicability of these modules to 7U, 8U, 9C, 9Z, 12FG, 12Z and 14MZ sets.Also: there's comment about how line-of-sight is essential or you lose signal. 3G phones work on a similar frequency, and you can use those with a brick wall between you and the T/X! We'll see how well they work when eventually deliver. Quote Link to comment Share on other sites More sharing options...
646su Posted May 15, 2007 Share Posted May 15, 2007 One thing I've noticed when using the binding process on the DX7 is that you require a switch harness with three wires on the charge & receiver wires in order to achieve success as it uses the signal wire to bind, OK with the JR type supplied but a lot of third party ones come with only two and won't work.

Essjay Posted May 16, 2007 Share Posted May 16, 2007 Ivor,A 3 wire harness is not necessary, as you can bind quite easily by temporarily moving your battery connector to a spare channel on the receiver, then use the bind plug in the batt position, and bind as normal. When completed just replace the batt connector. Quote Link to comment Share on other sites More sharing options...
Johnnie Posted May 17, 2007 Share Posted May 17, 2007 Have a trip to the US next week. If I bought a Futaba 2.4 Ghz over there would it be exactly the same as one over here in the UK Quote Link to comment Share on other sites More sharing options...

Johnnie Posted May 17, 2007 Share Posted May 17, 2007 just noticed on the futaba site that they also now have a 7 channel and 12 channel version of 2.4gh radio.http://2.4gigahertz.com/systems/radiosystems.html Quote Link to comment Share on other sites More sharing options...
Chris Hornby Posted May 19, 2007 Share Posted May 19, 2007 Folks on the other (now defunct)forum were getting a little anal about insurance issues with txs bought in the States not having the CE mark. I bought a DX7 in the States (made in the Phillipines) and it had CE marks all over it, even on the servos! Quote Link to comment Share on other sites More sharing options...
Peter Roberts Posted May 20, 2007 Share Posted May 20, 2007 http://www.horizonhobby.com/Search/Default.aspx?SearchTerm=9303&CatId=Link to Horizon Hobby showing the new JR 2.4 systems due for delivery July. Note they include equivalents to the JR 9 series Quote Link to comment Share on other sites More sharing options...
Len Ward Posted June 22, 2007 Share Posted June 22, 2007 Why have Futaba gone into 2,4 at such a low level? The intro of the Spectrum seemed to coincide with a flurry of advertising from the other manufacturers promoting 35 Mhz units,concentrating at the top end of the market.Have we any response from the Pro's out there on this?

John Cole Posted June 24, 2007 Share Posted June 24, 2007 Len Ward asks why Futaba have entered 2.4 with a basic 6-channel set. See my note posted in May: on the US site you will see they have a range of modules for their more up-market sets following on just behind.
