Sadflying Posted July 14, 2007 Share Posted July 14, 2007 Our first 2.4 6ex appeared at the club site last week was range checked set up on a jupiter and flew a very impressive test flight.However....subsequent attempts to link the set to a 6exap via futaba buddy lead have proved completely fruitless the 6ex is the master, 6exap the slave. The slave fires up but command cannot be transferred via the trainer switch.Trainer funtion on the 6ex is enabled.Additionaly,the 6ex has managed to completely clear its memory of the model on the four occasions we have tried to set up the buddy box!Your views would be welcome before I speak to Ripmax on Monday.

David Stembridge Posted July 22, 2007 Share Posted July 22, 2007 Hi All. Two friends and myself bought complete set ups including trainer aircraft and the Futaba 2.4 system from the Rougham show. This means that we have been in the fortunate position of being the first 3 membersof club with this kit. This means of course that we have used it for training via a buddy lead. On several occasions the box held by the student has given a couple of beeps and then powered down completly. the instructor is able to pick up control staight away. Then teh student box powers up again and the lesson continues. This has happenend with all combinations of tx 's, but always the same buddy lead which is where the finger of blam is pointing. You can go for several flights with no issues then have a couple of problems during one flight. A new lead is on order.I also agree about the supplied battery packs and have up graded.

the unmagnificent man Posted July 22, 2007 Author Share Posted July 22, 2007 Sadflying, sorry I missed your post on 14/7/07. You had the 2.4 as master and 6ex 35mhz as slave. Did you leave the slave switched off (it powers up with the 2.4) and remove the crystal? I know you dont have to remove it but on my buddy lead instructions it says that it helps! Also was the buddy enabled on the 35mhz radio. Go to settings and enable it before joining with the buddy lead. One more thing, the toggle switch on the 2.4 is 2 part, as you lift it with your finger it clicks, but then if you pull a little more and hold this transfers (or at least should)the control to the 35mhz. Did you get any reply from Futaba? Good luck Kelvin, where in the states did you buy your receivers from? Al Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted July 23, 2007 Share Posted July 23, 2007 We bought our set at Alan's Model Shop at Whitley Bay, just outside Newcastle. He advertises in RCM&E complete with e-mail address etc. It is a very good shop, very helpful staff and the website at www.alansmodels.com is well-designed and user friendly Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted July 23, 2007 Share Posted July 23, 2007 And they are in the process of setting up an e-commerce site at ms-hobbies.co.uk Quote Link to comment Share on other sites More sharing options...
John Sheehy Posted October 6, 2007 Share Posted October 6, 2007 A problem long overdue for solving in my view is the length of the receiver antenne (can't spell airielle). Is the 2.4 any shorter than the 35mhz.John Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted October 6, 2007 Share Posted October 6, 2007 Wow yes...... one of the main advantages my friend - tiny !! The Spekky job is only about 2" long.....think the Futaba is a bit more. Quote Link to comment Share on other sites More sharing options...
John Sheehy Posted October 6, 2007 Share Posted October 6, 2007 Great news for us all, but especially for scale flyers Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted October 6, 2007 Share Posted October 6, 2007 Yes. I was really pleased to have lost that long dangly wire hanging down from my little ALFA sabre EDF Quote Link to comment Share on other sites More sharing options...
John Sheehy Posted October 6, 2007 Share Posted October 6, 2007 The only downside seems to be the cost of receivers. I guess I can swap from plane to plane for now. Quote Link to comment Share on other sites More sharing options...
Dave Bran Posted October 6, 2007 Share Posted October 6, 2007 I have Futaba 2.4 running in a "Buzz" wing, where the Rec, ESC and battery are all sandwiched together, and the motor is only 50mm from the Rec............. NO ISSUESAlso an Eflite Thunderbolt, also no issues.Futaba may seem to have a longer aerial, but it's only the small end section on each leg of two flexible wires that's the aerial, the rest is cable so you can position them easily.

Tim Mackey Posted October 6, 2007 Share Posted October 6, 2007 I actually think the receiver are not bad value considering thir specs. Try a decent 35MHz synthesized receiver like an MPX or similar....not much change from 50 /60 quid. Quote Link to comment Share on other sites More sharing options...
John Sheehy Posted October 6, 2007 Share Posted October 6, 2007 It's not a question of value, I'm afraid to count the number of planes in my back room. At £65 a shot it's better not to think about it for now. Quote Link to comment Share on other sites More sharing options...
The real Ron Truth Posted October 7, 2007 Share Posted October 7, 2007 Anyone had experience of using 2.4ghz in petrol powered models to deal with engine rf noise? Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted October 7, 2007 Share Posted October 7, 2007 I presume you mean the emf generated by the ignition system? Not personally, as I no longer own any petrol powered models, but I would imagine there should be no problem, especially as all reputable model ignition systems have suppression circuitry anyway, and you would not be taking that away would you? The main reason that 2.4 stuff is so pretty much immune from "normal" R/F interference is that it is so high up the frquency band as to render it almost "invisible" to lower frequency interference. Spark ignition systems - although quite high amplitude, would remain well below this frequency, but good screening of HT cables etc is still probably advisable, as items such as servo leads and so on remain susceptible to such high power spikes.

Myron Beaumont Posted October 7, 2007 Share Posted October 7, 2007 Timbo Glad to hear you no longer have problems with long dangly thing hanging down Luxury --2.4 is good enough for everyone nowadays !(well it was before metrification! which probably hasn't reached Wales yet ) Grumbly Myron Quote Link to comment Share on other sites More sharing options...
