Admiral RX600SP 6-channel DSMX with Stability Plus Gyro

[Skeezix]

The subtrim in the servo menu is best used for when you have ailerons, elevators and rudders (dual type) separated into different channels. For the kind of trimming you are needing, it better just to use the trim tabs on the face of the TX. 2-4 clicks there is nothing. I'm talking like a dozen clicks or more.

I'm still working through the setup, but trying to achieve a setting on a two position switch where I have gyros ON in one position, and gyros OFF in another position. I absolutely DO NOT CARE about 'recovery' mode at all. I put the gyro in combo 'C', and assigned to a two position switch on my DX9. However, in one switch position, the receiver shows both the red and green lights on (green light flickers SUPER fast, red light is solid), and the other switch position show a brighter SOLID green light.

I've watched all 8 videos, but can't confirm if gyros are either ON or OFF with the setup I explained above. Can you advise?

Again, I just want gyros ON in one position, and OFF in another position so I can turn gyros on or off as I see fit, whether in the air or on the ground.

Ok - so SMALL amounts of subtrim are ok and will NOT effect gyro operations? I only need 2-4 clicks of subtrim to get to completely neutral.

Any gyro can accept a small amount of trim and sub-trim. However, if there is a lot of trimming, you should look at what the control surface look like (take a picture with your cellphone so you have a reference). Then set all trims back to neutral and adjust the rod so it looks like what it did in the picture. You may then still need a little trimming on the next flight but that's OK.

Hi all - question about centering the control surface on my plane with the RX600SP: must all centering be done manually, or can I use subtrims in my DX9 SETUP menu or the trim tabs to achieve neutral? Normally I would use subtrims, but not sure with a gyro (RX600SP)?
Please advise! :)

In my previous post what I found is that when Mix 1 is used ( I used switch G mixed to GER ) to control the gyro
the Throttle Cut function would not work. You can assign any switch to any function. Therefore I created the mix
like I stated previously to be able to turn of the motor.

The gear switch is usually on the left side rear. The throttle cut is usually programmed to the switch on the right side rear. Is the DX6 G3 different? In the pictures, it looks the same as the G2. The two switches should not conflict.

I just installed the Admiral 600 stabilizer rx. Set up is straight forward, but watching the videos is a must , there are some errors but you can work around them. I have used several other brands, am quite familiar with the theory and operation.I then tried setting up throttle cut (dx6 new version) and realized that the gyro uses the Gear channel and so does the throttle cut. After a very very interesting conversation with a motion rc associate and several disagreements I agreed to program Throttle Hold. Now what? not in the menu and I was not going to call back as some information in the videos is incorrect and our conversation was far from positive. So here goes how to program Throttle Cut or Hold. Go to mix 2, you have used mix 1. Mix Thr to Thr, rate -100,-100,offset-100, trim inh. I use switch A. Go to servo setup and scroll the low throttle setting to
-150. So now we have Throttle Cut.

Ok, so I started over. New Model. Rx600sp in default config. All pots all the way negative. Put stab in mode C.
Set up the Stabilizer on same switch as before. Pos 0, stab off. Pos 2, stab on.
Set my low,mid and high rates in tx. Assigned Rknob to Aux 3 for Master gain.
Set elev pot to 11 o'clock.
Powered up tx then rx.
Now when i turn off/on stab the throws do not change. When I increase/decrease the Master gain the throws don't change.
I don't know why it did it previously but works as it should now.

I've got oneof these in my Lippish P-15. It's worked perfectly, until today. Powered up as usual, launched and plane flew OK for a few seconds then started to oscillate in roll as if the gain was set too high. I'd never touched the gain adjustment since it was installed. Switching to recovery mode increased the oscillation. Switched back to just stability and safely landed. Turned the aileron gain down, launched again and it did it again, I again landed safely. Turned the aileron gain to minimum and launched again aand fter a few seconds it started to oscillate in pitch, attempted to land, but the pitch oscillations caused it to nose into the ground and flip with some subsequent damage. Again the receiver has worked perfectly until today. I made no changes to anything prior to the initial launch. Very windy today, gusts to a measured 16 mph, but I've flown it in these kind of winds many times. Anybody seen similar behavior? Any hints of how to trouble shoot this problem?

Knob at center should be where the pots are set.

I don't use this RX. I use the Lemon equivalent, so my responses are "generic" to the two. The knob is "master gain". It is a proportional relationship to your pots on the RX. IE, if your knob is in the middle, it is NOT representative of where your pots are. If the pots are in the "middle", that's about 50% gain. If your knob is in the "middle", that's also 50% of what the pots are. Therefore, if both are at 50%, the actual gain is then 25%.
When you start to use gyros that have both "normal" gain and "3D" gain, the knob does something completely different depending on how you set stuff up. At 50% ("middle"), there is ZERO gain for anything. "Normal" gain goes from zero to 100% counter-clock. "3D" gain goes from zero to 100% clockwise. Now you have to look at the color of the light on the unit and what those colors mean.

Thank you xviper.

New plane, new rx600sp.
I've come across something today a bit puzzling.. I have the rx600sp in mode C with a 3 pos. switch. In pos 0 the stabilization is OFF. In pos. 2 stabilization is ON. So far so good. I have adjustable gains on a knob. Turning the knob CCW decreases the gains. Rotating the knob CW increases the gains. Knob at center should be where the pots are set. So far so good.
I set up my dual rates and throws etc in my tx as always.
Looking good.
So, I fly my AL37 today (only it's third flight) and seemed to lose elevator authority. Landed it fine.
Put in a fresh battery and went to taxi. Checking my throws as usual and noticed my elevator had reduced throws and I was on high rates. Reduced throws on ailerons as well.
On my first flight I had some oscillation in the roll axis so I lowered the gains via the knob.
Took my plane back to the bench and discovered that when I switched from stabilization off to stabilization on my throws on elev. and. ail. would change. Decreasing with stab. on.
Then I adjusted the pots on the unit.
As I would increase the gains on the knob my throws would increase. If I decreased the the gains with the knob my throws would consequently decrease as well.
I'm stumped as to what's causing this to happen.
I think I'll go back to the beginning as if it's a new model and rx/stab.

I'm new to using this Admiral rx600sp.
I do have it in two other aircraft and they don't have this behavior.

When you hold the plane at any angle other than level and the control surfaces stay deflected, that's an indication that you've somehow selected "recovery mode" on these types of stabilized RXs. You may not have intentionally selected "recovery", but that's how the plane is reacting. This is the same as the Spektrum line of RXs when you throw the switch for "safe select". If you flew it like that, the plane will not (or be very difficult) to do a complete roll or a complete loop. Normal stabilized mode, when you move the plane, the control surfaces moves in the opposite direction to counter-act that movement, BUT, only for an instance, then they go back to neutral. They shouldn't stay.
PS. Perhaps the reason why nobody answered your previous questions is that nobody who read it, knows the answer.

[I-fly-rc-aircraft]

When you say stabilizer are you talking about a recovery "auto-leveler" or a standard gyro to dampen movement?

I'm in mode 3 or C..no recovery mode.Gains are switched on/off.

[F22trainer]

I don't know why I ask questions here since I'm usually ignored but I'll ask another. With the stabilizer on (on a 2 pos. switch mode 3) and the Master gain all the way up (set up with my Rknob on Ch 8) when I pitch or roll my AL37 the surfaces deflect and stay deflected until I level the plane. Is this "normal"?
TIA for any input.

My experience with the Admiral is 50/50...one does not work at all. It did when I set the model up at home, but went to fly and would not respond at all when powered up at the field. That said, the other one has been in use for a few years now. I tried to set it up with a full version DXe but could not get the mix to work. I upgraded to a DX6, Gen. 3, used the setup guide and the videos, put it on a 2 position switch and it works great - had to reduce the gains after the first flight but did not want recovery mode. No Master gain switch on the DX6, but several other members use it.

I have only used a gyro in one airplane. Just so you don't feel like you're being ignored, in my limited gyro experience having gains all the way up is extreme. Maybe try half gain and see what happens?

I only use the max gain to check correct direction correction.
