RE: Airplane rudder gyro
[quote]ORIGINAL: Big_Bird Howard, glad you straightened it out and got a good test in. Roger, see my post #233 above. The plane that I have the gyro in, Bucker Jungmeister, can be very squirrelly in a cross wind takeoff partly due to the main gear being so far forward. As soon as the tail comes up it really wants to weather vane in a cross wind. It is then hard to find the correct amount of rudder without over correcting. That is why I put a gyro in it. The gyro made a tremendous difference. [/quote] Thanks Ken Another question , do you feel it has to be in the heading hold mode to do the job?? I have used a gyro in the past on the ailerons and it was amazing, now I am thinking of a rudder gyro. Roger

RE: Airplane rudder gyro
[quote]ORIGINAL: Howard This is the follow up to my post #234 where I experimented with using higher voltages with the gyro. If you recall I have limited the test to using only an analog servo (I anticipate problems with higher voltage and a digital servo) and used a 4.8v four cell nicd pack, a 6v five cell nicd pack and finally a 2S A123 LiFe pack all with a Futaba GY401 AVCS gyro. I moved the gyro system to my test plane - a Sig 4*120 driven by an OS 120 AX with a 2S A123 LiFe battery and a JR 12X TX and a JR 921 RX. All of my servos are Hitec HS-5485 digital servos except the rudder servo which I changed to a Hitec HS-475. With everything charged and ready I moved my testing to the field and I am embarassed to say that after several attempts for the take off roll in the AVCS mode the best I could do were immediate ground loops. I turned the gyro off and flew the rest of the time with it off. When I got home and began investigating why the gryo system was not working I remembered that the 4*120 rudder uses a pull-pull system with the cable crossing from one side to the other so I switched the ''gyro direction switch'' (on the gyro body) to the other position. Two days later I flew another test flight and everything worked as advertised. My plans are to convert all of my flight systems to the 2S A123 batteries and this testing was to determine if the gyro would work at this elevated voltage - it had worked on the test bench and now it worked at the field. The 4*120 is not a difficult to plane to take off but, with the OS AX120 you need to apply a healthy amount of right rudder to keep in tracking straight. With the gryo active I simply advanced the throttle on take off and did not apply any rudder and it tracked straight down the runway. Ultimately this will go in an AT-6 or a P-51. I had the gyro sensitivity set at 70 for the AVCS mode, at 50 for off, and at 30 for the rate mode. The delay was set for approx 40 (hard to read) and non digital servo selected. If my narrative is not clear or I missed something please let me know. Howard [/quote] Forgive me for my ignorance , but I am interested in this setup but what is AVCS mode, is this heading hold? and if so why use this setup instead of reagular setup? Thanks for any information. Roger

RE: 2.4Ghz - Is it really ready for Hobby use ?
One thing I keep hearing , receiver in hold because of power spikes , needing better batteries and such, This is a problem I will never have , and the reason is very simple, I do not ever connect any servos directly to the receiver. The receiver has its own small battery (300ma would be enough) The servos have there own battery/ies. Oh and one more thing there is no direct electrical connections from the servo/battery to the receiver. so nothing can ever feed back to the receiver causing lock ups , failsafe or anything like this. Why aren't more people doing something similar??? Roger

RE: 2.4Ghz - Is it really ready for Hobby use ?
[quote]ORIGINAL: Xantos Hi Guys , I lost a Kingcat yesterday due to what I can attribute to unexplained 2.4 issues. I was using a JR DSM9 radio with the 9ch Rx and 2 extra remotes , the kingcat was rigged with 2 x Powerbox 2800mA batts for Rx , 4000mA Powerbox batt for ECU , Powerbox evolution , Powerbox smokepump , Jetcat Afterburner ring and a Jetcat 160. Aircraft had 25 flights on it without incident data logger had shown Rx and receiver location to be OK - No fades or holds. Here was an aircraft that was perfectly setup , redundant systems etc and a troublefree history flying at the and same airfield ,but on Sunday , on the first flight after takeoff and into the 2nd circuit the Gear dropped and turbine shutdown and no control was restored until impact. Everything was detroyed ! This is the 2nd time a similar thing has happened to me with a 2.4 system, the first time was with a large Gas heli which went into Failsafe but regained control after a few scary seconds , never flown the heli after that.Again the set up was a fully redundant power system , additional remote extensions and over 10 incident free flights to prove the system The point is - the 2.4 system seems to have too many quirks and bugs most of which are encountered during setup i.e while binding or after binding some systems will cycle the gear on powering up or a bound system will require to be recycled or have to go thru the binding process again because lights on one remote will keep flashing etc . Or even worse you could just randomly get hit by the system going into failsafe for no assignable reason whatsoever. I know there was a huge controversy about Ali's Hunter crash on RCU sometime ago and the thread ran into many many pages with various people pointing out to the cause of the crash and advocating redundant power supply systems etc. It definitely beyond doubt that the weakest link today appears to be in addition to batteries , also our preferred primary control systems My post is not JR or Spektrum specific , I know Futaba also has its own issues in high operating temperatures etc but I have no first hand experience with Futaba I also know that there are many people out there that have many successful flights with 2.4 systems I myself have logged probably more than 200 flights since the spektrum conversion modules came out IMHO I think if we look at pure percentages, the older 35, 40 , 72mHZ systems are relatively troublefree when compared to the 2.4gHZ technology out there. The percentage failure rate on the 2.4gHZ seems to be unacceptably high ! In my 20yrs experience with the older FM/PCM systems I've NEVER had a failure that could not be explained Interestingly the Europeans do not seem to have switched over wholeheartedly to the 2.4gHZ tech. My observation is from 3 consecutive years that I have visited the JETPOWER show in Germany - most of the pilots (90%) seemed to prefer the 35 or 40mHZ system - I wonder if there is a reason for this ? My question for all of us to consider is : Is the 2.4 technology really ready for the hobby ? Or are we enthusiasts guinea pigs for a evolving technology where the manufacturers are doing their R&D at our cost ? I am definitely pulling out all my old but reliable 35mHZ receivers and possibly go with a twin Rx RRS system - No more 2.4 for me ! Xantos [/quote] There is a specific JR radio on 2.4 that has problems that I know of, which JR model is this , it reverses channels at some given time with no reasons whatsoever. But in this case it might not be with the 2.4 as much as with the transmitter encoder system.... Roger

RE: spark ignition for turbines
[quote]ORIGINAL: SpiderJets I remember using spark ignition on JPX turbines drove the 35 MHz FM RX nuts. Same with your system, or did you test it with 2.4 Ghz ? It was rather dangerous as it also drove the servos beyond the mechanical limits of both the gears and the surfaces+links. I had to switch off the RX as long as I had the spark ignition button pushed in, and moved the throttle servo by hand. Personally, I do not see the big advantage of a probably rather expensive and "heavy" system over replacing a cheap and light glow plug every now and then...? [/quote] I keep repeating, there has been no problems whatsoever , not with the starting or with regular operations. The system is not that expensive and quite light. I am using 72 mhz. Roger
