Admiral DSMP Stabilizer Channels Combined

[Luke_1350]

Hi there,
I know this probably a really basic question that I am just missing the solution but I needed some help. In the past I have only built and flow small electric RC planes with Spectrum receivers and controllers with pretty much no problems at all. Then I was given a larger, mostly built, gas engine aircraft just to complete building(essentially just finishing the electronics). This is where the issues start, multiple people had been messing with it so by the time I started working on it all the wires had been exchanged and moved around and the engine wouldn't start. luckily through a mixture of experience, YouTube and online manuals I was able to wire everything correctly and get the engine running. With one exception, for some reason on the receiver the elevator and ailerons give the same output signal(When I pitch up or down, the ailerons do full bank to either the left or right). I don't think this is the controller( A Spektrum DXe) because to my knowledge there is no way to combine channel outputs on it. Any help would be appreciated.
Thank you.

What kind of plane is it? What is the “wing and tail” type set on the RX? From your picture, you’ve got ALL your dipswitches OFF. Is that what you want? You’ve also got something plugged into the ELE and RUD port but nothing plugged into the AIL port. Is that what you want? Have you read the instructions for the RX? Watched all the videos?

It is a wing and traditional tail style aircraft- I am unsure what type but it looks similar to a cesnna 172. I unplugged the wings and took them off to work on it. I turned all the dip switches off because the receiver was not mounted flat or facing the right direction.

There are some great you tube videos explaining how to program this receiver. They're worth watching!

Dipswitches J4,5,6 should be set to indicate "normal wing/tail". Having them OFF may turn off the gyro but it doesn't set the wing type and may serve to confuse the RX. If you don't want the gyro to be working, then all gain pots should be at MIN. (counter-clock). TX should be also set to "normal wing".
PS. This receiver has been know to have glitches and reliability issues. You may have one of those. Try a different non-gyro RX to check.

I will try that, thank you.

Just read thread for first time.. one thing (I'm not clear on) you said Rcvr not mounted flat or in right direction.. this Receiver has only ONE orientation that will work.. Flat, Up, and Fwd. (with servo connectors towards the tail of the A/C Normal Wing j4 j5 j6 should be On, On, Off

That may be true for some gyros, but it is not always understood by everyone. A gyro device can easily be mounted slightly NOT flat, slightly angled to the side and backwards (servo wires coming out the other side). You may understand that there is only one way to mount it but that may not be clear to everyone and hence, problems can arise.
EG. A HobbEagle gyro can be mounted on its side, upside down and backwards and still be made to work. Another good example is the gyro on a BananaHobby V-22 Osprey. The unit is mounted (on purpose) at a tilt (when looking at it from nose to tail). It's the nature of the plane and the gyro has to be mounted this way in order for the plane to hover and fly level.

Good info! especially on the Osprey. And you are absolutely right... my comments were specifically to the Admiral 6 (from the first Video on the Motion RC page)... and a very good point on initialization for Angle of Attack.. I'm having extreme trouble setting up the Admiral 6 with a DX7S... can't figure out how to setup the Mix for an Off/On Switch... thxs... Kenny B

I can't be certain of the following ........................... I believe there is a video on how to do the switches and mixes where the TX doesn't quite meet the requirements for normal setup. Try to find the setup video when dealing with either a DX6i or DX6. I recall it involved a couple of switches and/or mixes to do one thing.
