Norman Eyers Posted May 15, 2013 Share Posted May 15, 2013 Hi all, cant comment on the Hobbyking gyros because could not get my hands on one. However purchased a Dymond 3 axis unit from Germany and not wishing to try it out on anything special I fitted it in an aircraft made from several other models.It flew quite well but had a nasty habit of going a bit mad when turning into wind. After fitting this gyro the trtansformation was amazing. It was stable in all conditions and laughs at strongish winds. Can rtecommend this unit to anyone wanting to venture in.

YakMad Posted May 17, 2013 Share Posted May 17, 2013 Norman, Thanks for the info on the Dymond 3 axis gyro, I have been looking at one for a while but was afraid it was similar to the HK versions which I hate as both of mine cause the servos to jitter badly and I would not risk them in any model. The funny thing is I bought 3 when they came out first, gave one to a buddy of mine and it worked perfectly but my two are rubbish. Quote Link to comment Share on other sites More sharing options...
Norman Eyers Posted May 19, 2013 Share Posted May 19, 2013 Hi Yakmad, When using the DYMOND 3 axis gyro, it is important to set the gain pots (there is one for ail, rudder & elevs) to minimum, then gradually increase the gain on each untill the respective control moves slightly as the model is moved in the appropriate direction. DONT do this outdoors as any breeze will affect your setting up. Now if the respective servo judders or twitches the control then the gain is too high. Only small perceptable movements in the controls should be needed for first flight. Note also that with this gyro you can set up one switch on your tranny to give normal control (stabalized) or off or heading hold. For first try out, take off with it switched OFF, gain safe hight and switch on (AVC or normal position) and watch results. If needed switch off, land and readjust. Also note that when the desired stable flight is obtained, when you switch your receiver switch on the model at startup and normal is selected first, hold the model level for several seconds as the gyro senses a level position then the controls will click into their center positions ready for taxying or carrying it out to runway. Hope this mouthfull is helpfull. Norman-E Quote Link to comment Share on other sites More sharing options...
Clive Hall Posted June 13, 2013 Share Posted June 13, 2013 I am new to this forum, but have been following the discussions of the Orange RX3S V2 for some time. I have some, and an Eagle Tree Guardian, and have been testing them in an old battered TwinStar, and a WOT4e. Both types work well when set up correctly, the Guardian being clearly the better device, capable of much more than the less expensive RX3S. I have been flying both models in winds around 16 to 18 mph, gusting to over 20 mph measured on a Skywatch Xplorer. In spite of these conditions, made worse by low level turbulence, the aircraft fly safely and for the most part smoothly. Landings in particular are well stabilised and do not seem to present a hazard. However the RX3S does have one annoying habit - the servos chatter continuously while it is powered, regardless of whether it is switched on or off at the transmitter. I am beginning to believe that whether this happens or not depends on the servos. I have tested it with every type of servo that I could get my hands on and the results are interesting. Newer servos, e.g. Hitec HS81, HS55, HS325, HS485 and JR DS821 all chatter non-stop. Servos such as JR NES507, NES517, Sanwa SAN102 and the anonymous servos in the WOT4e do not chatter. Neither does the relatively new Spektrum A6000. This servo gave me a clue - on some forums it has a poor reputation for having a wide dead band, which I think points to the explanation. My theory is that the RX3S has a ripple on its output signal at all times and that servos with a narrow dead band see this and cannot settle down. The other servos do not see this signal defect and so sit quietly in a model. What it needs now is someone with an oscillograph, a programmable digital servo and a servo programmer to look at the signal, and to experiment with varying dead-band widths. Unfortunately I do not have such equipment. If I am right the solution seems to be to use the RS3X with servos that remain quiet. I feel that with the others there is a risk that the pots will suffer premature wear leading to failure. Quote Link to comment Share on other sites More sharing options...
Pete B Posted June 14, 2013 Author Share Posted June 14, 2013 You may have a point there, SB - I've also seen it mentioned over on RCG that the 'better' servos suffer more. Those were my findings with my Cub - HS81's jittered like mad but the cheapie OEM sevos on the Fox weren't affected..... Pete Quote Link to comment Share on other sites More sharing options...
JohnSom Posted June 16, 2013 Share Posted June 16, 2013 I have set up my 3 axis version 2 gyro on my micro fusion and everything appears to be behaving as expected except my on/off switch (set on 'Flap/Gyro'. This switches elevator and rudder on and off but the ailerons remain permanently on regardless off the switch position. I have tried changing the Y lead and the servo themselves but with no success. I have also tried using the gear switch with the same mystifying result. I have run out of ideas. Can anyone out there offer a possible solution ?

Norman Eyers Posted June 16, 2013 Share Posted June 16, 2013 Hi John, Make sure you have not selected Helicopter mode instead of acro. (plane). Check transmitter carefully to see if you have inadvertantly got another switch selected as well as the one your using. Also check that the switch you use for switching gyro on and off is not on same channel as used by ailerons tjo i suspect you are using Ch 1 on receiver and using splitter. If you still have a problem run through gyro set up again and try again. Norman Quote Link to comment Share on other sites More sharing options...
JohnSom Posted June 16, 2013 Share Posted June 16, 2013 Thanks Norman I checked each of the points you highlighted with no success. I rebound the Rx on to a fresh unused channel and set up the gyro from scratch, again no improvement. In desperation I disconnected each of the two aileron servos in turn. The left servo behaved normally, the right servo chattered violently and as they are both fed off the same lead via a splitter I can only conclude the fault lies with a dodgy servo. I'll fit replacements tomorrow and try again - I've had enough for tonight ! John Quote Link to comment Share on other sites More sharing options...
Clive Hall Posted June 17, 2013 Share Posted June 17, 2013 J S, perhaps you should not think too badly of the servo that chatters violently. It could be one of the best servos you own. Chattering on an Orange ORX-3S is obviously a weakness in the ORX-3S circuit design, rather than a fault in a servo, because other more pricy devices of similar kind do not do this, even with servos that chatter on the Orange thing.

JohnSom Posted June 17, 2013 Share Posted June 17, 2013 Oh dear. Guess how I pulled the new servos into place ? Still I can always solder new leads on the originals. At least I reckon I have sorted the problem with the Orange stabiliser. John Quote Link to comment Share on other sites More sharing options...
Norman Eyers Posted June 20, 2013 Share Posted June 20, 2013 Can anyone help? Just took delivery via HobbyKing of F-TEK 30A 3 axis staberlizer. No instruction sheet is supplied so I have found out, and the makers web site provides details but in a RAR folder which I cant decipher. Anyone out there possess an englishy copy. Would br gratefull for any info. Norman. Quote Link to comment Share on other sites More sharing options...
Pete B Posted June 20, 2013 Author Share Posted June 20, 2013 Easy-peasy, Norman. Got to the product page, click on the purple 'Files' tab bottom right of the page, and the manual is a PDF in there Pete Quote Link to comment Share on other sites More sharing options...
Norman Eyers Posted June 21, 2013 Share Posted June 21, 2013 Bless you Pete, Many thanks for info as i did think i was going to be left with something i could not use. Having had so much success with a german unit in high wind flying i was desperate to use one on a larger aircraft for photo use.

Phil Winks Posted August 12, 2013 Share Posted August 12, 2013 Posted by scott cuppello on 23/02/2013 10:19:22: There is a file marked "V2 Manual" it covers both versions, and should give you enough information to set this unit up, it certainly worked for me. Downloadable instructions are common for e-tailers, it keeps costs down and offers a constant source for upgrades/revisions....things are changing, many people will learn how to set up planes, electronics, etc, via You-Tube, Forums, etc, thousands of our customers don't seem to have an issue with it. Hi scott I do hope your still watching this thread I'm just a little perplexed here as there really is only one file in the product files tab here or is this item listed in more than one place cos if it is I can't find it lol Phil Quote Link to comment Share on other sites More sharing options...
Pete B Posted August 12, 2013 Author Share Posted August 12, 2013 I don't think he'll be that interested, Phil - Scott left HK a few weeks ago I don't think there ever has been a printed V2 manual but all the info you need should be in this thread. If you can't find what you need, just ask - better in your other thread, I think..... If it helps, someone has made a video on installing the V2: Pete Edited By Pete B - Moderator on 12/08/2013 21:49:49 Quote Link to comment Share on other sites More sharing options...
Ian Southerton 1 Posted September 11, 2013 Share Posted September 11, 2013 I have an orange 3axis v2, a few times I've felt I've briefly lost control of my plane as the elevator has not responded, then a couple of weeks ago, I came out of a roll and dived head first into the ground. I put it down to my lack of experience. Makes me wonder if it was all my fault. I have the flaps set so I can switch it off, so may try without it next time. Ian.

Formtex1947 Posted February 16, 2014 Share Posted February 16, 2014 Hi does any one have any experience with using the unit with say a JR 35 MHz set up such as a JR 77 Rx? Quote Link to comment Share on other sites More sharing options...
Rick Young Posted May 8, 2014 Share Posted May 8, 2014 I have used the Orange 3-Axis V2 stabilizer in the roll mode only using my Futaba 7c tx and rx and it worked well. However when trying to add the yaw channel I find that with the stabilizer only switched off it is not possible to move the rudder to the right or at best it has a very delayed reaction and then does not center. I have tested this problem on another model with another Orange stabilizer with the same results.Has anyone had the same situation. ps The pitch mode seems to working as advertised.

Rick Young Posted May 9, 2014 Share Posted May 9, 2014 Phil, Thanks for your reply but I think that I have now solved the problem. Both of the models being used to diagnose my yaw snag were fitted with FR-SKY TFR-6 Futaba compatible rx's. I replaced one with a genuine Futaba rx and all is now well. It would appear that although I have never had any problems with the TFR-6 before that it is not compatible with the Orange stabilizer in the yaw mode.

Phil 9 Posted May 9, 2014 Share Posted May 9, 2014 Mine is on a Futaba FASST Rx. I have mine now hooked up to rudder and elevator and all seems fine. I had a problem at first with elevator but managed to solve it buy rotating the module in the model with pins to the front (unlike in the video above) ailerons next. I have ailerons with a servo in each wing on separate channels. the stabiliser seems has a right and left aileron output but only one input. should I only connect one aileron?

Phil 9 Posted May 9, 2014 Share Posted May 9, 2014 I have it working on one aileron but I don't seem to be able to make it work both Quote Link to comment Share on other sites More sharing options...
