Admiral RX600SP 6-channel DSMX with Stability Plus Gyro

[sfmadmax]

Thanks for the feedback , understand better now.
so with the admiral is there an easy way to check if my gyro is working ??? I'm not talking about the recovery feature. Just the gyro in general, for example if I wiggle the plane should I see movement in the alierons. ???

This is my first admiral, I've always have spektrums

I have read a'lot of posts where pilots mentioned their default gains were perfectly fine. I guess this depends on the plane???

For sure. Gyros tend to need less gain the faster the plane can go. Oscillations begin at higher speeds for some reason and hence, gain should be dialed down. The smart money is on turning all the gains down before the first flight and gradually increasing them on each subsequent flight until the point of oscillation at top speed. Then you back it off a bit and you're good to go. Even better is to have the gains on a master dial or knob on the TX. Leaving it on default gains and then being "perfectly fine" is a matter of chance. I don't want to be the one who doesn't take the proper steps, have the plane go into oscillation and not be able to slow the plane down soon enough before it rips off a control surface or vibrates itself into the dirt. It's all "perfectly fine" ............................... till it isn't. Then you never post about it or tell anyone because you know it was an avoidable occurrence. As you do the walk of shame and come back with a garbage bag full of foam pieces, all you can say to onlookers is ............................ "Duh, I don't know what happened. It just became uncontrollable and the sticks had no response." (Said with a not quite convincing dumb look on his face.)

Has any one used the RX600SP with the F-27 Evolution a delta wing from Horizon Hobby? If so what micro switch setting did you use for the stabilization mode?

Thanks! Would 25 percent be approximately 9 o'clock?

You need to figure this out for yourself. Turn the pot all the way from one end to the other. That's 100%. Now estimate 25%.

I purchased this RX and put it in the Freewing 64mm Sabre. I flew it tonight and it got the speed wobbles bad. It looked like it was going to shake itself to death:Whew: I slowed down to just above a stall speed and it settled out and I landed. I am new to programming a gyro so I figure the gain is too high. My question is how much do I turn the ailerons down? I guess I go counter clockwise but I have not seen any documentation on what the usable range is. It is currently set the way it came.

Turn your gains down. Never use such a gyro RX on the setting it came with. Start at less than 25% and go up in small increments.

I'm pretty sure what I said about re-defining "level" is correct. Recalibrating the gyro is associated with gyro functionality...a different thing.

You sorta answered your own question. This unit is a re-label of the Lemon Stab Plus. The major difference is the Lemon has an owner recalibration for level feature that the Motion version has removed. If you don't like what the receiver thinks of as "level" your only option is to alter it's attitude as mounted in the plane. How well this unit works as a SAFE replacement seems to vary with the plane. It's perfectly acceptable in one of my planes, and not worth having in another.

Wouldn't the below show that motion didn't remove this. If calibrate the gyro sensor to "your level", reinsert RX in to plane and it should be "your level" what I mean by "your level" is just the user definition of level.

• August 17, 2018 - If you have been experiencing setup issues with the Admiral RX600SP the following is advice that should be of help: To calibrate the gyro sensor, please put the stabilizer PLUS on the table and power it on (absolutely still, no people jumping around, no wire movement…etc. slight vibration will cause gyro calibration failure indicated by the red LED flashes twice). The gyro will calibrate automatically at the time when power is provided. Within 2 seconds you should see the LED flashes twice. Green flashes twice means calibration is OK while red flashes twice means calibration failed due to movement.

I have 8 of these Admiral 6 channel/Gyro receivers. I set them all to the default "Gyro ON"/"Recovery" Mode. My main concern/question is: with the Bind button depressed in "Recovery" mode, the models all recover in a shallow dive and shallow bank. Does anyone know how to level them out in "Recovery" mode? (I saw the comment to raise the back 10 degrees).

Thanks! As I suspected, left the gains too high. Lucky me, got the plane down. The gains are at about 15% now, to start over, and I'm on Combo C, so I can leave the gyro off until I get some altitude and turn it back off if it gets squirmy again. I'll get it dialed in. Thanks again.

[xviper]

I had left the gain controls at the default, 50%. Could this have been the problem? Too much gain for that really sensitive airplane?

I've reconfigured the receiver to Combo C and put the gyro control on Switch C, on and off. Before I fly it again, any suggestions as to where to set the gain controls?

Yes. Oscillation means gain is too high for any given axis. Oscillation increases with speed. When oscillation begins, either turn off the gyro if possible or power down and slow down and land. Most of my planes with a stabilizer works well at about 25%, some less, some more. Turn down till it doesn't oscillate at the fastest speed the plane will go. If it doesn't oscillate, turn gain up little by little till it does begin to oscillate and back it down. Then you should good to go.

Hi, my first post here, so please forgive my inexperience. I got back into R/C this June, after a 25 year time-out, but having been flying models, one type or another, since '63. It was amazing how everything had changed!

I bought 2 Admiral RX600SP receivers to try and installed one in a RocHobby SuperRoc MXS. Guess it's called a 3-D, but it's currently right at the ragged edge of my rustiness and I thought the stabilizing receiver might help, especially in the wind.

So: (sorry for the length, want to eliminate questions regarding the install, if I can.)

- I watched the videos on set-up, read the Quick Start Guide and bound the receiver to my DX6.

- I set the dip switches, J4, J5, J6 all to 'on', as this plane has separate aileron servos and I use Aile&Aux1 rather than a Y-harness. I have the ailerons configured as Flaperons, as well.

- I set the Mix1, as directed.

- I mounted the receiver on the original servo/receiver platform built into the airplane. Aligned fore and aft, with the servo pins to the tail of the airplane. Upright.

- I planned to leave the receiver in Combo A (default) for the first few flights, planning to reconfigure it to Combo C after flight testing.

- Ground testing. Range check ok. Per the video, tilted the plane while holding down the 'bind button', ie: into Recovery Mode. Flight surfaces all moved in the wrong direction. Switched the J1, J2, J3 switches and the flight surfaces were correct. I could see very small movements as I tilted the airplane while out of Recovery Mode.

Now. First flight. Low rates on controls. Took off paved runway, using a little up elevator. Almost immediately, I noticed the airplane beginning to oscillate in pitch. Then I applied a little left aileron to bank back over the field. Immediately, the airplane began to oscillate in roll, while continuing in pitch. The roll oscillation rapidly intensified until the wings were oscillating to about 60deg, one direction to the other, while pitch was about 30 deg.

Thinking I was going to lose the airplane, I cut power and tried to level out (this all happening in about a second and a half.). With power off I realized that the oscillation was diminishing and in a few seconds it stopped altogether. Caution being the order of the day at that point, rather than trying to make it into a pattern and land, I simply let it fly straight and landed downwind in the grass, without damage. (Being VERY glad I hadn't been flying a $1000+ EDF jet.)

I went back through everything and couldn't find any mistakes... except maybe one. I had left the gain controls at the default, 50%. Could this have been the problem? Too much gain for that really sensitive airplane?

Any update? Did that fix your issue?

Sorry about that. I only get online a couple days a week. I did what you suggested with no change in the Hawk but it did work in the Hornet. Both with identical setups as far as I can tell. I am probably going to take the gyro out of the Hawk anyway as it's locked in without. I have a couple Lemons and an Eagle sitting around that I haven't gotten around to using as well.

[dkalwishky]

Awesome, thanks!! I plan on flying this morning and will try that out!

Any update? Did that fix your issue?

[icepirate3]

Yes; I have experienced that. I called Motion with the plane in front of me and after some quick troubleshooting the guy had me set the 5% in the mixes to a NEGATIVE 5% (-5%) and that fixed it. I guess I like to run my gear switch the opposite of just about everyone else. I wish I could remember the guys names, he was very helpful and smart.

Has anyone encountered any problems with the gyro not initializing after reversing the gear switch?

[icepirate3]

Look at the monitor and see what the end point numbers (for the gear channel) are for when it used to work to when you reversed it and it no longer works. Make sure the end point values are the same but at opposite ends of the gear switch travel. It should read something like -100 to +100. When you reverse it, it should be the opposite.

Good tip! I will look at that when I get home. Thanks!
