Flight Control Issue with Admiral DSMP 6ch Receiver with Stabilization

[Denniswpb]

I'm having a flight control issue with an Admiral DSMP 6ch Receiver with Stabilization. This is absolutely driving be crazy and caused my plane to crash twice!! Fortunately I was able to maintain little control and save it from complete disaster. Here is the situation: I have a new Hobby King Phoenix 2000 that flies fantastic with a Spektrum AR610 6ch receiver. I ordered the Admiral 6ch receiver with stabilization and put it in. I selected Mode "C" so I could turn stabilization on or off, and verified it does go on/off with switch A on my Spektrum DX8 gen 2. I did have to place the 3 gyro switches to "ON" in order to get the stabilization to operate in the correct direction. So, all switches are "ON" except J6, which is off. During pre-flight all flight controls work perfect and stabilization is correcting in the correct directions (I had 3 other experienced RC flyers verify this). CG is also verified. Upon launch (it's an electric sailplane), it is as squirrely as it can get and I loose most control. It pitches up/down, rolls, and I fight it trying with very little control to get it down without destroying it. It does this with stabilization ON or OFF, and it makes no difference. I make no other changes and put the Spektrum 6ch receiver back in, and it flies perfect. I contacted tech support last week and they sent me a replacement Admiral receiver, and it did the same exact same thing today. I put the Spektum receiver back in, and again, no problem. Could the electric motor be interfering with with Admiral receiver??

Does the plane use crow or flaperons?

[Denniswpb]

Ryan.. No. Just has Flaps on AUX 1

[ryramZ]

Is it mounted firmly in the aircraft?

[Denniswpb]

It's fastened in with velcro flat and the pins are facing rearward.

Also, did you set up the mix like the quick start guide shows? Sounds like you have the right idea. Combo c assigned to a two position switch instead of the bind button. Your mix still needs to be the same as the quick start except your using A instead of I.

[Denniswpb]

Correct. I initially had it set to the bind button the first time using Combo "A", and it worked. When I went to fly it, it was squirrely on launch and hit the ground. I then changed it to Combo "C" and launched it with Stabilization OFF, which was verified. Again, it was squirrely on launch, and again, hit the ground. I was able to make a "semi-controllable" crash and was able to save the airplane. Nothing that some epoxy did'nt fix..

[ryramZ]

Use the provided double sided tape. It's more rigid. How are the gains set? What do the lights do at both switch positions?

[Denniswpb]

The only other thing I had to change in order to get the receiver to initialize was I had to reverse the GEAR servo.

[Denniswpb]

The gains are set to 1:00 position, I can't remember off hand what the LED light blinks with the switch toggled to disable the stabilization, but it does turn it off

[ryramZ]

You should not have had to reverse the gear switch.

[Denniswpb]

If I didn't, you could not activate any of the switches for control stabilization. You could not use switch "I" (bind button) in Combo "A" or any other switch in Combo "C". Only when I reversed the GEAR switch I was able to turn on/off stabilization on switch "A" or go into Panic mode with switch "I". I sent a video to Wayne showing this. Here is a link to the video:

Switch A is the gear switch. You can't use that one. Replace your A in the mix with any other two position switch and it should work. That is why you had to reverse it. Reverse it back and try it. If A wasn't your gear switch what you've done should be fine. That explains why it happened to two different rx as well.

[Denniswpb]

But even with stabilization OFF, it still was squirrely and hit the ground.

[ryramZ]

In the video you posted you are not able to switch the gyro because you have essentially mixed it to itself. I'm telling you that's what's up. Your rx is confused because the mix is wrong. Probably why you had trouble.

The firmware is designed to mix to or with the gear channel as is shown in the QuickStart. That's why it worked for you when you did it to the bind button. You simply cannot mix it to itself and have it work. Try H like I showed in the videos or any other two position switch and you should have no trouble.

[Denniswpb]

I'll give it a shot and post the results... Thanks Ryan!!! :Cool:

[ryramZ]

No problem, thanks for stopping by. Let us know.

[Denniswpb]

Just wanted to follow up on the original post. I changed to switch B and everything seems to work now. Also, earlier I stated I had to reverse the gear switch, what I meant to say was that I discovered the gear switch was in the reverse position, and I then placed it back to the normal position.
Thanks for the assist!
