RE: JR1222 RECEIVER switches
The stock switch that comes with the JR1222 powersafe receiver turns both off at the same time. If it fails or comes unplugged the receiver stays on. Mike

RE: Converting a JR 12X to use the Weatronic Module
[quote]ORIGINAL: oistein The best way is to open the transmitter and take out the DSM2 module, as the module version and non modules version is almost the same internally. Then you must know the pinout of the connections to the module and connect the power and ppm pins to your weatronic. I believe the 12x will only give you 8 channels when using the ppm signal. [/quote] Although the dedicated 12x and 12xMV are physically similar, the firmware is not the same. The 12xmv includes the ability to transmit on 72mhz in PCM and PPM through the software. I don't think there is a PPM signal at the fixed module in the dedicated 12x to tap into. Mike

RE: Weatronics....considering a change .is it worth the investment?
[quote]ORIGINAL: rhklenke [quote]ORIGINAL: Woketman Bob, I fly Futaba so I am NOT bashing Futaba. But what I find inescusable is that the top brands do not give a real time indication of signal quality. Some sort of alarm to let you know that the signal being received in the aircraft is getting weaker than a set amount. Maybe the new Futaba 18 does this, but certainly not my 12FG. Weatronics allows you to see this. Were it not for the legendary crappy customer service, I'd be flying brand W. [/quote] Well now that there is telemetry in the Futaba systems, I too would like to see signal strength as one of the parameters that could be sent/stored. However, I have *never* had a occasion where I wanted to see it, so not having it was not a big deal to me. The FASST RF link has been rock-solid for me in much more harsh environments that typical RC applications, so I have not had the desire to monitor the signal strength. The data is out there on the receiver sensitivity of the FASST system vs. its closest competitor and it is so far superior that its no wonder the FASST link performs better. Before I'd go to any other system, I'd want to be sure that it had similar performance. *That* is the best way to prevent loss-of-link, so I'd want to be sure that I was not giving up that quality just to get telemetry... Bob [/quote] Bob, where can you find this data? I checked the Futaba site and it only lists dimensions, current draw, weight. Weatronics lists receiver sensitivity at -100db. Thats pretty darn sensitive. I'd like to see how it compares to Futaba and others. Mike

RE: Weatronics....considering a change .is it worth the investment?
[quote]ORIGINAL: David J Ruskin Guys, Multiplex has the real time signal quality % figure right on the TX screen all the time. simples David [/quote] Unfortunately, M-link doesn't have FCC. Graupners HOTT also does this though and is FCC'd. Still, neither record RSSI , tx frames, rx frames at every second of flight like Weatronic does. HOTT also has programable receivers in similar fashion to Wea. Futaba is lagging way behind in this kind of stuff although new 18MZ has some telemetry functions but, nothing indicating the conditon of the RF link. Not mentioned is that the Weatronic uses 2 patch antenna to transmit to 2 receivers offering redundancy. It also hops across the entire 81 channel band ( other hopping systems "FASST & DSMX" typically hop across approx 30 channels) and it "looks" ahead to avoid the busy ones rather than just hopping across them. Roger's files, if I remember correct, showed very low #'s on both receivers although not identical, thus either a problem with the equipment or very harsh RF environment I've never seen anything but, outstanding RF #'s on my Wea equipment.

RE: Weatronics....considering a change .is it worth the investment?
[quote]ORIGINAL: Gary Jefferson I switched a couple of years ago and ended up selling the system. It was virtually impossible to get a new receiver when I had a new project. Even if you could get one the wait time could be months. Many excuses; new ownership, the company is moving to a new bullding, etc. Finally, I just gave up. It might be a superior system but it is of no value if you cannot buy new receivers when needed. I would recommend you check very carefully with guys that are currently using the system before switching to see if the availability is any better now. I would also recommend reading the thread referred to here because you can see the actual information available in the system. The information is available but you have to understand how to interpret the information before it is of any use to you. At the time the thread was running all of the time most guys were just posting their results so that someone else could interpret them. [/quote] Gary, if you were trying to purchase equipment from the USA dealer, that is where the availabilty issue lies. If you order direct from Wea's online shop, there is no issue. I had a nightmare of a time trying to get product from Weatronic USA, very nice guy but, one excuse after another, claiming product is not available, hold ups in US customs etc. Since I order from Europe, whatever I want arrives in 2 weeks from time of order. Although I'm in Canada, I have it shipped to my USA mailbox to avoid Canadian import costs so, I know there's no issue shipping to USA. It's not a perfect world though: the two downsides to dealing with the company are that their primary language is German, English communication can be weak. 2nd, is that their customer service is poor ( could be related to issue #1). Customer service does seem to be improving though. If you can "live" we these two issues, the reward is a superb product that seems to be technically ahead of everyone else although, it may admittedly provide too much info for some people. Not here to "sell" the system to anyone else but, I do use it exclusively in my jets now and really like it. Mike

I don't know the outcome & RCU has been on the fritz so I couldn't check it. - John. [/quote] Yes, I know he sent his log files to Weatronic for review but, I don't think the outcome, if any, was ever posted. Although it's never good to loose a plane, it can happen and does happen with any system. One of the advantages to the Wea system is that should something happen, there is an unbelievable host of a data available that can be used to assess it. I think I recall seeing Roger's files and remember that his radio link quality was below the norm for his entire flight. He was losing alot of frames. I can't say whether it was a problem with the equipment or whether it was the RF environment it was operated in. With other setups you would not have this information and would be wondering if a servo locked up or your battery dropped out, Weatronic's data log would tell you if this was the case as well. I'd love to know if it was ever brought to conclusion. Mike

I know it's probably 2yrs away from production :( but, I'd really like to get a transmitter that gives me more than 8 channels with Wea ( currently that's what I get on 12X in PPM). 10 channel PCM does not work well as the servo movement is "sloppy".

RE: Weatronic 2.4 RF diagnostic tool
[quote]ORIGINAL: zl1wn Synchronising 2 servos I am trying to synchronise 2 servos that drive an aileron on a large sailplane. I have set them up as master/slave and set the amount of aileron movement, by setting the master servo endpoints. However, when I mechanically link up the slave servo and then go to synchronise, (which shows on the slave servo) during the synchronisation the servos drive to their limits, which is well past the endpoints I have set and the synchronisation fails. I don't need them to synchronise right across the servo range, only a small part of that. So what am I doing wrong Ideas please. Thanks Ross [/quote] Ross, If I understand you correctly, the sync is failing because the servo's can't drive to their limits because of the mechanical setup? Can you not disconect the linkages, run the servo sync, then re-connect linkages and set end points? It's been a while since I've done it but, I believe the servo's do run through their entire range during the syncing process and it is important to not have the linkages connected because of possible binding. Hope, I've understood your issue as you intended? Mike

RE: P70 catastophic fail?
If the "online" hobby shop is an AUTHORISED jetcat dealer, you should have a warranty. Always check to make sure you're buying from an authorised dealer. If you bought it from someone unauthorised, I think you'r out of luck. BTW, I had a P-80se blow up twice from "overspeed" Both times were covered by warranty. It was purchased from an authorized dealer. Jetcat had no sound explanation for the overspeed. The best they could do was suggest that "possibly" there was a restriction in my fuel system that "suddenly" freed up to cause the overspeed. I doubt it, the jet is still being run with the same fuel system. Both times same maneuver, going over the top of a 1/2 reverse cuban at full power. First time with 6hrs on engine, second time with 4hrs. BTW, why not name the dealer so, others don't have this issue? Mike

RE: PST Panther advice
[quote]ORIGINAL: Helijet Two totally different aircraft. Having sold and flown many PST Panthers over the years I still remain impressed with the airframe. I currently have three. You cannot compare the UFlash with the Panther. Totally different designs and flight performances. Both will fly fine off a short strip with the engine you have chosen. As for quality, I must disagree with the posters statement. The PST Panthers are very well engineered and constructed for an Arf. I have an UltraFlash with a P100 so have direct experience. I do agree on the struts, they are scale as offered by PST and are not designed to take a lot of hard landings. Go simple with Robart. Any other questions just fire away. [/quote] Didn't mean to imply the PST is poorly engineered, just that the CARF is definately a better engineered product. Examples of area's that could be improved on the Panther are the main gear struts ( as already ageed upon), the nose gear mount and former. The nose gear mount will break far too easily in a botched landing where u bounce on the nose gear ( even mildly). My former had to be cut and adjusted to allow full retraction of the nose gear. Also, there's nothing to keep the nose gear straight when it retracts so, it can oftern turn and jam. I didn't like the fuel tank being held in with elastics, Didn't like the rudder servo location, although its usable , it doesn't allow for perfect geometry. There's a ton of small things like that wrong with it, that aren't necessarily deal breakers btt, these are the kinds of things that I'm talking about when I say it's not on the same engineering level as the CARF. I do have to politely disagree with Paul tho, I find the Flash much easier to land :) Mike

RE: PST Panther advice
[quote]ORIGINAL: damagedgoodes Thanks Mike, Would you say that both models would come in at about the same finished weight, and would the CARF UF be a bit anaemic on the K-80 in you're opinion? Also do you think the UF is worth $1000 extra over the Panther (Panther is $1600 with exhaust and UF is $2600) for basic airframes. I haven't seen any other jets other than my Falcon in the flesh (I'm the only turbine flyer here) and the nearest club with jets is about 1000 miles away so RCU is the next best thing for advice/recommendations. Cheers. Dave [/quote] Hi Dave, My Panther is just under 25lbs, I have a classic Flash, not the Ultra but, it's 21lbs with a Rabbit 100 in it. Yes, I do think the Flash is worth the extra $1k, it's a much better quality airframe with better engineering. You'll definately get more performance in the Flash than with the Panther. The K-80 will likely push the Flash at about, 165-175mph, the Panther around 120mph. One other thing I forgot to mention about the Panther is it has a silly little 2L fuel tank so, safe flights are around the 5min mark. The Flash with both main and wing tank can carry a lot more fuel, with a K-80 you'll get 10 min flights. Mike

RE: PST Panther advice
Dave, jmho as I have a PST Panther that was my first jet. It would fly perfectly fine on a K-80, I had a P-70 in it, flew fine with that but, struggled to take off on grass, pavement was no problem. You should be able to get it down on your 400 foot strip. Ours is 300ft and I can get it in there although I went through a learning curve and have bounced it, knocked off the gear , etc on a few "forced" landings. I changed from the PST struts/ wheels to Behotec ones. The PST struts are a poor design and after replacing parts on them a few times ( which were expensive and had to be shpped from Thailand) I went to the Behotecs. The strut would bend at axel joint on anything less than a perfectly executed landing. I hated the hydralic brake system, it worked fine but, as stated, I had some gear problems early on and everytime I had to remove the gear for repairs, I had to drain and bleed the bloody hydralic system. What a PITA. Switched to air when I went to the Behotecs. If I was ordering new, I'd confirm that Robarts Ziroli panther retracts would fit and then go for those. Actually, I probably wouldn't buy one again. I know you want a scale ship but, I'd go with a CARF UF , set of Prolink retracts and have a blast on your 400ft strip. The UF is very rugged and can take some learning without being damaged. Mike

[quote]ORIGINAL: gooseF22 when I had the 160 in it, we kept dialing it back...ended up around 24-26 lb thrust.. plenty to go vertical (midwest).. If you have all the speed out of your system, then build it light weight and use one of the smaller lighter engines.. thats what Im doing this winter.. I saw one fly recently with a Tam pipe, lighter servos, and less than 20lb overall weight..yes, less than 20lb.. with a P100.. it flew absolutely beautifully.. would slow to a crawl.. plenty of smash.. Im going to put a wren 100 in mine with the stock pipe, and toss the pilot/cockpit, and take out the smoke.. that should bring me in around 22lb.. FWIW [/quote] Totally agree, have flown flash with Rabbit 100 at 21lbs, and Cheetah at 22lbs aircraft weight. With the lighter engine, the plane handles SO nice, still does 180mph, take off and landings in 150ft. It is faster with the Cheetah, about 225mph but, doesn't "feel" as light and becomes more of a straightline speed plane.Also, higher residual thrust and more time to spool down with a bigger engine. I like the way it will slow to a crawl with the smaller engines. I fail to see why people continue to hang bigger and bigger engines in them? You get marginal speed gains and lose handling. The Flash was designed as an aerobatic sport jet, not a speed plane. Mike

RE: Unexplained loss of control
Surprised no one has asked but, is it possible that you simply stalled the aircraft? I have seen more radio hits, crashes and "I don't have it's" in my day that were aerodynamic stalls than I can count. FAR more than failed equipment. Last summer I watched a big Corsair launch, immediately break left and pile into the ground. The pilot explained to me that his ailerons "reversed" just after launch as he was putting in right stick but, the plane was going left. At the crash site the the ailerons miraculously went the right way. He reasoned that it must have been an electronic glitch in his JR radio that reversed them when he took off and the scarey part is , he truely believed this. I suggested that he stalled the aircraft on take off as his take off speed was too slow and pitch angle too steep. 'Impossible" he touted, "he's flown the aircraft many times before". Interestingly, a video shot by a spectator later showed the ailerons full right in the direction of his stick movement but, because the plane was stalled it banked left. Mike
