RE: Weatronic gyro question
[quote]ORIGINAL: ddennison I don't know why the system can't mange the servo speed being slowed? [/quote] It's due to the unusual way they implemented it. Watch gigacontrol when you use tx slowing and you will see that it is the horizontal marker that moves slowly, so the servo which is represented by the vertical marker, slowly follows any programmed curve. But if you use normal tx speed and gigacontrol slowing, it slows the vertical servo marker not the horizontal marker so it can not follow a curve. Wea then moves the servo in a straight line from the start point on the vertical axis to the end point on the vertical axis at whatever slow speed you have selected. If you have a top hat shape curve, the start and end points are the same on the vertical axis so there is no movement of the servo at all. What you had done by having both tx and Wea slowing was mixing the two so the tx control moved to the middle of the top hat and instead of the servo going straight there, Wea was slowing it down in gettting there, so the servo just started to move by which time the tx control signal had reached the end of the top hat thus commanding the servo to come back to where it started. The result was that you got a slow small servo twitch. By switching off wea slowing you allow the servo to go at full speed to follow the curve at the speed set by the tx.

RE: New Behotec e-Tract electric gear
Way back in 1986 I bought a set of electric retracts from Mick Reeves which had normal size lever arm micro switches at both ends of travel. You can buy much smaller micro switches nowadays. By use of a spring touching the leg they staggered the start time so they did not travel perfectly together. The switches were mounted in a way that you could alter their position a little to allow for slightly different than 90 degree angles. All done without any electronics.

RE: Processing Weatronic Data.
I think the G force calculation would be hard to do and not much use due to various inaccuracies. My Wea GPS is rather poor, turns have the shapes of hexagons instead of circles, speed suddenly varies up and down by 100mph in a second and it regularly shows the model doing circuits and flypasts tens of yards behind the pits! So my experience of the Wea GPS data is that it is totally unreliable for doing any precise work. On top of that you have the general GPS problem that height data is much less accurate than lat/long data, so using it to calculate G in a loop will be poor even if your GPS unit is working well. I carry an Eagle tree low G sensor in my jets, in stand alone mode it records and displays the highest G level encountered in the flight, so it’s not as good as G per each manoeuvre but at least I get an idea of the maximum stress being put on the aircraft. http://www.eagletreesystems.com/Standalone/standalone.htm

One thing to do is save each rx model file in the latest version of gigacontrol before updating the tx and rx, as model files made in much older versions of gigacontrol can't be read by the latest version so they can't be restored to the rx after the rx is upgraded. If you have any micro rx you will need the special cable to attach them to the usb port of the pc. Tx module and 12-22 rx are updated by their micro sd card. The sequence is: save rx model file old gigacontrol just in case update gigacontrol save rx model file in new gigacontrol update tx update rx bind rx load rx model file made in new version of gigacontrol

RE: weatronics question
You do need to have servo slowing at the Tx, the wea servo slowing will not work. If you use Wea servo slowing it doesn't follow the curve, it just goes end to end as if on the usual diagonal slope. The following shows the door curve I use on my EE Lightning which is a simple doors open-shut. For doors shut-open-shut just put in a raised bit at the left end so that the curve is symmetrical left to right. You have to time where in the door sequence the legs do their bit, you want the legs to start coming up at the start of the sequence, not at the mid point, so use similar curve to the doors but shifted to the opposite end.

RE: Thoughts and ideas regarding gyro on ailerons
[quote]ORIGINAL: turnnburn What I am looking to accomplish primarily is to make my final approach to be more wings level and less wings rocking and rolling. Additionally this airplane tends to drop the right wing pretty hard if stalled or if too much up elevator or too rapid of elevator control is applied during flare and just prior to touchdown. [/quote] Wing rock has two main sources, either dutch rolling, or turbulence. Dutch rolling starts as fishtailing, the high dihedral effect of such a swept wing then makes the plane roll in reaction to the yaw of the fishtailing. A gyro on ailerons will damp the rolling from side to side but won't stop the fishtailing. A gyro on rudder will damp the fishtailing which in turn will also damp the wing rocking. Highly swept wings have a high gain from yaw to roll, so often you see the wing rock much more than you can see the fishtailing that is the root of the problem. Turbulence tends to come as random direction and strength rather than a rhythmic back and fore of dutch rolling and would need an aileron gyro to damp it. My Trim Sabre will suddenly start to yaw and roll off line to one side if slowed too much on finals, it's a warning that it is too slow rather than a need for a gyro to try and damp out the warning! If you are getting wing drop from pulling back on the elevator, a gyro won't stop an asymmetric stall and will probably make it worse, the real cure is to learn where the critical point is and not pull back into it. If the plane is dutch rolling/wing rocking at slow but safe speeds then a rudder gyro will help a lot, an aileron gyro will improve the look but will still leave the slight fishtailing. Either way it will look and feel better.

RE: Thoughts and ideas regarding gyro on ailerons
[quote]ORIGINAL: turnnburn I guess it depends upon what the airplane is doing when banked. I think TP is correct, the nose is probably yawing some what in the opposite direction (adverse yaw) and therefore the gyro used on rudder should be in effect a yaw damper and help coordinate the turn. this is certainly true on full size swept wing transport type airplanes. [/quote] Adverse yaw only occurs whilst aileron is applied in the roll in and out. There is no adverse yaw while banked unless you have to hold quite a bit of aileron on in the turn. Whilst rolling in or out the yaw damper will reduce the adverse yaw but when turning the plane must be yawing in the direction of the turn and the yaw damper must apply rudder away from the turn.

[/quote] Emcotec, Powerbox, Weatronic, Multiplex, the Germans do seem to have a predominance in some quality stuff. I've pretty much decided my next jet tx after the 4000 will be Weatronic. For the larger jets their Rx with 22 or 30 outputs saves a lot of wiring between rx and power distribution boxes, plus the programming in the rx is better than many tx - considerably better than a Mpx Royal Pro tx for example. So the combo of the tx and the Weatronic rx is extremely powerful and versatile. My English Electric Lightning is running 21 servos and two gyro gains from 11 tx channels and every one of the 21 servos is independently programmed, plus the fact that it has 8 regulators each of which only feed specific servos means I can arrange the servos to allow for any one regulator failure/overload not to take out its twin function, e.g the tailplanes on separate regulators, door servos not on same regulators as any primary control, and so on. The amazing flight data recording that no other system has, has been very helpful in tracking down some interesting problems by proving for example, that there was no radio glitch, no loss of frames, no faulty data from the tx stick pots or cpu, and so on. I can understand siclick not wanting to be tied in with a smaller firm whose survival is not assured in these difficult times, although so far it is the mighty Graupner and not small Weatronic, Jeti etc, that has turned its paws up in the air. If SJ Propo had not bought into the radio part, all the Graupner Hott customers would have been left high and dry. So the size would not deter me from buying into Weatronic. H

RE: Weatronics....considering a change .is it worth the investment?
[quote]ORIGINAL: Gordon W Hi Harry How voltage stable are the regulators? Does the Wea system let you do an after-flight check of the minimum voltages produced by each regulator during a flight? If so, do the 4.8V regs remain solid at 4.8 and the 6V ones at 6 during a flight, or is there some voltage drop under load? Cheers Gordon [/quote] Hi Gordon, it doesn't record the output voltage, only the voltage of each battery at the input to the regs. Each reg is rated at 5A and only has to run 3 servos. The software blocks you from putting multiple servos of the same tx channel onto the same regulator. For example, reg 1 powers servos 1, 9 and 17. You have 4 aileron servos to assign, and the tx is sending aileron on channel 1. You assign servo output 1 to the incoming aileron channel, and the software immediately blocks outputs 9 and 17 from also being assigned to the tx channel 1. So you assign the second aileron servo to output 2 and it immediately blocks outputs 10 and 18 from being assigned to channel 1, and so on for each next assignment. This prevents all the other servos of that one function that would operate and draw max current at the exact same time from being powered by that one regulator, you have to use outputs from 4 different regs to run those 4 servos. Also, should any one reg fail, any other servos doing that function will be powered by a different reg and so will still work. The entire backplate of the 12-22 is an aluminium heat sink for the regs. cheers, H

RE: Weatronics....considering a change .is it worth the investment?
I briefly used the Wea 35mhz rx and then bought the 2.4 system not long after it went on sale. My 2 main reasons for buying it were the need to run about 15 servos without changing from my 12 channel tx, and my desire to have the data logging about the radio signal as I like metal coated jets which present a difficult environment for 2.4. Every system has pros and cons.  I think there have been some problems with the interface to certain futaba tx.  The cable that connects the tx to the wea module is a weak link.  Wea's attitude to flaws with their design, and there are flaws, is that they are perfect and your equipment is the problem.  The customer service if you are not german can sometimes be bad, they speak english fine but have sometimes given the impression that they aren't interested in anyone who is not german.  My current contact with tech support suggests that is rapidly improving though. All wea rx are highly programmable.  This allows you to use just one tx channel per function which frees channels for more functions such as lights, gyro gains etc.  For example you just use one channel for ailerons and in the rx you map it to as many outputs as you need, each output having its own multi point curve, travel, centre, failsafe and so on.  Mixing can be done in the rx too, but can't be switched on and off from tx. After each flying session I copy the flight data to pc and check the frames data just to make sure I am not having problems.  The tx module has 2 aerials as do the rx and the system records, per second, the number of frames your tx gave to the wea module, how many the wea transmitted, how many that each of the two rx systems received, what control position you transmitted for each channel and what position the rx then actually passed to the servo (there can be differences due to rx mixing, gyro input, failsafe etc).  It also has voltage and current data (no current data in the non 12-22 rx).  There is a lot more data as well but those are some of the more useful ones. I also carry the gps module and like to see the 3D ribbon of the flight in google earth as well as typical speeds and heights. Most rx can be had with 1, 2 or 3 axis gyros built in.  The 12-22 rx have built in power management with 8 regulators feeding different groups of outputs so you can arrange considerable redundancy, voltage can be selected 4.8 or  6v independently for each of the 8 regulators so you can mix in any servos that don't work on 6v, and it comes with a "fail to on" switch as standard.  If you buy a normal rx of any other brand plus for example powerbox channel splitter with programmability, multiple regulators, failsafe swiches, gyros etc you will pay far more than the price of a 12-22 gyro rx. I know the flaws in wea because I have used it for a few years and it is still the only system I use in my jets and I have no immediate plans to change.  The one thing that has really irked me is the customer service but that has recently improved much and I can email direct to their tech guys who understand and reply in good english.

RE: Weatronic 2.4 RF diagnostic tool
Here's a strange problem to be solved. It's a continuation of the gyro glitching that I reported earlier. I have passed the details to Wea for them to try and solve it but it sounds so odd it may need someone to have encountered it before to know the answer. Previously Wea found that both axis gyros were kicking at certain engine throttle settings and I confirmed it with ground runs and found the engine rpms that were guilty. At that time we assumed some microscopic engine vibration was at a harmonic of the gyro vibration and giving it a physical kick. Rx is 12-22 gyro 2. At certain engine rpm, both gyros glitch. Only the aileron gyro is active at the moment so it is just the ailerons that i am watching but if I turn up the rudder gain it kicks and vibrates too at the same time. At one rpm the ailerons kick hard left, at 2 other rpms the ailerons vibrate. Engine has been back to manufacturer and its balance checked. Data shows that the aileron gyro is sensing a violent right roll when none exists, the other axis gyro is also seeing rotations at the same time. Note that the kick on the ailerons is always left aileron, so the gyro is always sensing a right roll. I would expect a wave form such as vibration or an electrical or radio interference on the gyro to produce kicks in either direction at random. Now for the really weird bit. Despite having the engine checked and mounting the rx on foam and held down only by rubber bands, the gyro troubles were exactly the same. So I removed the rx from its mounting and held it in my hand, not touching any part of the model, and the aileron kicks and vibrations still happen at the same rpms as before!!! The MEMS sensor is not getting a physical vibration, it must be getting some sort of electrical or radio interference. But since that would come as a wave form, perhaps from the ECU or pump, why would it always kick left aileron? And how is such interference affecting the gyros anyway? I took batteries and wires and throttle-ecu servo cables out of the model and kept the radio stuff totally separate from the turbine battery and pump cables, held the rx in my hand and still the ailerons kick left, or vibrate at the same engine rpms as before. I am sure that the always kick to the left is a clue of some sort. Perhaps the interference causes the gyros to re-boot or a momentary power loss to the gyros and as they come back on line they kick in one direction only? Otherwise any electrical or radio wave form passing through the gyro would surely cause it to kick either way? Next time out I will take an Emcotec line filter and put it on the throttle-ECU cable to block any dirty feedback from the ECU and see if that stops it, but I thought that Wea Rx were protected from dirty signals on the servo wires anyway? Anyone got any ideas? Harry

RE: JHH AND YELLOW AIRCRAFT PHANTOM F-4 TURBINE CONVERSION
I built the Yellow F-4 for turbine but had to retire it after a handful of flights. I would like to do it again but with the knowledge gained from the first one - 1. I used the Tam's bifurcated pipe made specially for this model, with a PST J600R engine of 14lbs thrust. Flight weight was about 16-17lbs. It felt like it had less than 10lbs thrust. I think the pipe and the engine-pipe gap destroyed a lot of thrust. I emailed Tam several times to ask about the gap but never got an answer so went with what PST said. If I was going to do it again I would build a thrust measurement rig with a variable engine-pipe gap and do some experimenting to find the optimum gap and find out just what the net thrust is before deciding if it is worth proceeding with the build. Mine could not make it to the top of a loop! The bifurcated pipe was extremely loud. 2. The wing is shallow so there is very little material above the retract cut-outs. The high wing loading meant high landing speed which needs wheel brakes. Applying brakes causes the leg to want to rotate backwards, applying lots of torque to the retract mounting but there is little material left to hold it and so after a few gentle landings the wing skins split open across the top of the retract bay even though the wing was glassed and extra applied at the root because of the plug-in system. I guess the original d/f didn't have wheel brakes so didn't get the torque from the legs. If I did it again I would apply either very heavy glass or carbon cloth over that area of the top skin to take the bending load and stop it from splitting. Mine was not worth repairing because glassing over the split skin would add yet more weight to what was already badly underpowered. Other than that it looked good and flew well. Harry

RE: multiplex Royalevo
Prior to HitecUSA taking over the US distribution, the distributor Karlton Spindle seemed happy enough at the sales level prior to the Royal going on sale, and the Royal outsold the Profi by many times. The radio forum had lots of N American users of the Royal, in comparison to the Profi series. Things were going very well in the right direction for them in the USA until HitecUSA was forced into being the distributor and brought it to a halt. Most people found the radio very easy and logical to program in comparison to the muddled jumble of the Asian radios. Once you get the concept and stop trying to force it to behave like the awful JRtaba software, many people threw the manual away, not needed. The manuals aren't great, but if the Asian radio manuals are so good as you claim then why do Americans make a living writing third party manuals for Asian radios like Anne Marie-Cross, Harry Higley etc. Multiplex did care about the US market, Karlton Spindle had a big hand in designing the Royal.

Also, do I need to change the hardware from 35 Mhz to 72 Mhz?[:o] [/quote] Multiplex Tx are not made in a fixed mode like Asian radios, so all you need to do is select mode 2 in the software. See the instruction manual. afaik, 35Mhz is not legal for model aircraft in the USA so you need to get a 72Mhz module, or go to 2.4Ghz. HitecUSA is now the distributor for Multiplex in the USA but doesn't want competition for its radios so has not applied for FCC certification for M-Link 2.4GHz, thus effectively killing off Mpx radios in N America. However HitecUSA has offered a way to put its 2.4GHz module into the Royal radios, see http://www.rcgroups.com/forums/showthread.php?t=1125154
