You're convincing me! By the way Ken, if things pan out OK Sean and I could be up for a bit of Destructive Smashing at the Hump tomorrow.

I'm starting to get pretty ticked off with my Tx. On of the trim switches (which I had replaced already mind you) has fouled again and no longer seems to work! Maybe I'm too rough. Maybe I do stupid things like fly in the rain and dust and dirt. Maybe I enjoy the hobby too much and in such a way that the gear isn't tolerant of. It certainly cops a flogging.
They need to start putting those rubber booty things (like what's over gear sticks etc) over the sticks and rubber buttons instead of contact switches so they stand up to the punishment. A rubberised surround wouldn't go astray either.

Thing is my 15 year old JR with thousands of hours of use has never suffered any of these issues. They don't make them like they used to Interesting thing is as the popularity of SC keeps growing, I really think buying a radio that isn't a 2.4ghz is craziness. It's just dumb luck that we don't have more problems than we do. I know most of the regulars and know I don't clash with them. However I'll be flying and you see someone turn up and fly that you don't know... and no one has asked your frequency. That's great service that you're getting there Ken.

I agree with yooz guys. They should make the sets more waterproof. It's an outdoor hobby! Even wet grass, etc just happens.
Callun if you reckon you're rough on your gear ... h-hmmm. At least you had yours in a plastic bag in the rain the other day!
Steve yes I agree 2.4G is the way to go, but I'm still worried about a coupla aspects ... cost of equipping with 6 Rx's at $180 each, vs $20 each now for Coronas! Plus they're having probs with 2.4 not working in carbon fuselages, so the hotshot DSers in the US are (as far as I can tell) all using 72mhz.

I agree with ding, the older JR trannies are way better than the modern ones. I think someone mentioned it above, for plain old slopin, 6 channels is heaps, even if you go multi/full house. But, if you are like me and get drawn into scale then 6 wont cut it, 8 or more is needed. My 3810 is great and Paul (slopefun) picked up a second hand unit which is beautiful. If you have the $$'s go for the Multiplex or the Graupners, real art in workmanship. check out rctradingpage.com.au from time to time, you may grab a nice second handy. There is this at the moment www.rctradingpage.com.au/article.php?id=15 NICE! Steve

Glad to hear of the good service Ken. I just purchased a second hand Multiplex Evo 9 for a song. It has some pretty cool features, with frequency scanners/checkers, timers, etc,. One good feature is if I go to a site and flick on the transmitter, it scans to make sure nobody is on the same frequency. If someone is, it won't transmit. It will probably take a while to get my head around it all. The JR 2610 has worked flawlessly for me but I find myself wanting a little bit more from full house gliders now that I am delving into thermal duration/F3J. This should allow me to get the best from my planes, and future proof me for a while atleast. Eric

Congrats on the Evo purchase Ezza. That'll definitely do all the clever things you need to do for a high performance glider.
Portfox, the Co-ckpit SX is less than $400 for a synth Tx and synth Rx. It will do a 4 servo wing fully (so you can have brakes!!!) plus it does flight phases. For full-on competition there are more capable radios, however they are all at least double the price and that's really not what the Co-ckpit is for, although I would have no hesitation for using it in comps if I were to get back into that kind of flying.
IMHO, the really big deal in glider mixing for slope use is CROW BRAKES!!! The ability to really control your approach speed so you can land more safely and in small/tight spots. 2 servo wings just don't compare, and that's what most radios I see in use are limited to.
As to 2.4GHz, freedom from frequency clashes is a huge benefit. That needs to be balanced against issues of signal blanking around carbon and interference (which at Bald Knob has stopped 2.4GHz users from flying so it is a real issue). So it is not a silver bullet, instead it's another choice that needs to be considered in light of your flying needs. The fact is that frequency clashes are rare - very painful when they do happen, but rare.

Ok an embarresing NOOB question......... If I have a Synthetic Tx like the cockpit SX must I have synth Rx's or will it still also work with a standard crystal Rx?

Should work with a standard crystal Rx, same as a standard Tx with a synth Rx.

Vanders,
what Callun said. I've had my Tx bandwidth tested and it performs exactly the same as a crystal-driven Tx. Most of my Rx'es are crystal-driven and they all work perfectly.
The flip side is also true, synth Rx'es work just fine with crystal Tx'es. So if you think a synth Tx is in your future you can buy synth Rx'es now and get the Tx when you're ready. BTW I have heard the Corona synth Rx is not a good 'un. I use Multiplex Rx'es, (hardly a surprise right??) and they've just come out with a really nice small 6 channel synth Rx. I have one, it's going in my Reaper.
To be balanced about Corona stuff, I haven't heard one bad report about their crystal 6 channel Rx and I have heard several very satisfied reports.

Ok, my Flash5 has given up........
1. Is 2.4 a complete write off at Bald Knob? 2. If price was not an issue. Multiplex Cpit SX or JR PCM 9X? Are there many benefits of paying more $$$ for the JR?

No 2.4 isn't a complete write-off at Bald Knob. Nothing is guaranteed up there, you just have to work at it until you get a setup that doesn't give problems.
The JR 9303/9xv2 is one of the very best allround Tx'es and glider Tx'es on the market, bar none. Joe Wurts did the glider software and it is extremely capable. It has 9 channels, is available in both 36MHz and 2.4GHz. If you are seriously looking at spending that kind of money I suggest you compare the 9303 to the new Futaba 12FGA and to the Multiplex Evo 9 channel.
There is no doubt that the 9303 is significantly more capable than the Cockpit SX. What it is not, is easier to use. The Cockpit is the easiest computer Tx to actually get full use out of the functions it has, and it has absolutely top class ergonomics, so it's good to hold and use. That said, I'm sure you won't have any trouble learning the 9303 if you decide to go that route.
Whatever your choice, Go Great!

Hi Ken, I'm looking at buying a 9X II within the next week. The Cockpit SX is nice too but I have a thing for JR radios . I've been reading over the 9x manual and it does look powerful but I had no idea it was as good as you say, very encouraging! For what it can do I think it's quite reasonably priced too. My plan is to get the 36Mhz version and buy a 2.4GHz module at some point in the future. I have read that there is a slightly increased latency in doing so (like PCM) but I can't imagine that I'd actually be able to notice something so slight (I always liked the way my Reaper flew on PCM). What are your thoughts on that idea?
