Ultymate Posted August 19, 2008 Share Posted August 19, 2008 This has just come up on the Flying Giants frum and also RCUHey guys several of our members have PM'ed me asking I put up an alert on the JR 9303 2.4 version. Apparently the voltage regulator next to the gimbal is cutting into the wire bundle that rests on it. It appears to be a simple fix, or you could do some preventive maintenance, OR better yet, if you find your wires to be frayed, give Horizon service a call. BUT, since this problem is confirmed with multiple pictures on multiple radios, I would suggest either checking the condition of your radios wires, or having Horizon tech dept give it an eyeball before flying the radio again.Now, we are in no way slamming JR or the 2.4 9303. Its a great radio, and by making sure this little issue is fixed or avoided, it can continue to be a great radio.The picture attached is 1bwana1's radio, and it shows just how severe this problem can be.The guys have a thread going on here to discuss the problem and the fix.

Ultymate Posted August 19, 2008 Author Share Posted August 19, 2008 Link to the thread on Fyling Giants as followshttp://www.flyinggiants.com/forums/fg107/33360-2-4-ghz-9303-potential-frayed-wire-issue.htmlI don't know whether this is applicable to the 9303 on 35megs or just the 2.4 set Quote Link to comment Share on other sites More sharing options...

YakMad Posted August 20, 2008 Share Posted August 20, 2008 Thanks for the heads up must check my DSX9 to-night, just to let you know Horizon do not supply JR in the UK, you would need to contact MacGregor instead www.macgregor.co.uk.

Tim Mackey Posted August 20, 2008 Share Posted August 20, 2008 Yep...think H/H only do Spektrum radio in the UK ( ex helger racing ) Quote Link to comment Share on other sites More sharing options...
Tony Heaton Posted August 23, 2008 Share Posted August 23, 2008 I've been in contact with MacGregor since this came to my attention. JR have come back with the statement that...."the wiring in a DSX9 is different from (early?) X9303's. Other refinements have been made so this should not be a problem with a DSX9."However, I think that people should check every couple of months just to make absolutely certain in their own mind that all is well.

Doug Ireland Posted August 24, 2008 Share Posted August 24, 2008 Just had the back off my DSX9, no clashes seen. thanks for the heads-up! Quote Link to comment Share on other sites More sharing options...
winchweight Posted January 8, 2009 Share Posted January 8, 2009 Chaps, just to let you know, there is increasing evidence that this IS a problem for JR DSX9 tx in the UK. They (MacGregor) are now agreeing that as a precaution all should be checked and the wires rerouted. I did mine and it took just 5 mins to do. Quite a few people on another rc forum (RCMF) have found a lot of chaffing.Out of interest, it has also been noted that the wire which runs down from the aerial to the circuitry, crosses the pcb edge and moves when the aerial is moved, e.g. when turned for flying after being in your box. A suggestion has been made that this could chaff the aerial wire, and mine had evidence of some small scratches which would substantiate this. Routing around the cover securing post prevents this.JR (USA) guide to modification I have added the RCMF thread below because of the serious nature of this. Mods - If this is a problem please bin the link.RCMF DSX9 thread with pictures Quote Link to comment Share on other sites More sharing options...
Ultymate Posted January 8, 2009 Author Share Posted January 8, 2009 This was assumed to be an old chestnut that had been dealt with but apparently not it's come up on another forum that I moderate on. Dave Wilshere knows all about it at Motors and Rotors. Quote Link to comment Share on other sites More sharing options...

Doug Ireland Posted January 12, 2009 Share Posted January 12, 2009 Just checked mine, no damage but there was a good bit if slack in the wires. Did the mod as described which took all of five minutes.Thanks for the heads-up! Quote Link to comment Share on other sites More sharing options...
