View Full Version : AP 2000i, setup, but still not working
Hello,
I've got my ap2000 to show off, calibrate and I can set it to 70 or 90% but the fma sensor is not responding, or something is just not working. The heli flies the same with it calibrated or off. What would be my next step to test the units?
Bergen EB, dx7
Thanks,
Kyle

Have you set Stab IRx, and cycled the power several times to make it stick?
Hmm, nope. Will try that tonight. I guess I missed that in the manual.

As Tony mentioned you need to verify that you have activated the IR stab function in the setup menu of the AP.

If you are getting it to show Cal and the gain % you must have it turned on.
Do this: On the bench, calibrate the unit, bring in high gain (90% or so) and cover two adjoining sensor eyes at a time. Note the swashplate response. What are you seeing?
We have seen a few of the sensors defective of late and they show reduced stabilization response. Perhaps that is what is happening here. Let me know what you find.

Actually your FIRST step should have been to test it on the ground as Mark stated by turning the gain way up, and moving your hand around the sensors and making sure the swash tilts away from your hand.
No way you want to put it in the air and see what it does.
You (for your sake and your heli's sake) should know exactly what it is going to do, and that it is operating correctly before even spooling up with it.
Also verify that calibration is working on the ground also before putting it in the air.
Calibration is working, IR Stab is on, off to calibrate to gain at 90%, sensors covered by my hand but nothing happens.

Did you removed green covers on the sensor unit? :idea:
They were red, yes I removed them.

Want to stop by the Corona filed this weekend?
Is the DVD ready yet?

So, just to confirm.
AP2000i display shows gain is @ 90%.
IR STAB is on in the setup menu.
Nothing happens at all when you put your hands over the sensors.
The signal wire coming in from the IR sensor has two servo plugs on it. Make sure they are not reversed (i.e. they are plugged into the right socket.) They are polarized with futaba tab, so you can't get that part wrong, but you can put them in the wrong place.
Red one should be second from bottom.
If that is OK, then go into the engineering menu.
Press both "Menu up" and "Menu down" at the same time while the ap2000i is powered up.
Scroll through until you find ADC1, ADC2, and ADC3.
While on these menus, move your hand around the IR sensors and watch the ADCx readings, the values should be changing.
If you see nothing on the ADCx menus, then check your connection plug into the FMA IR sensor and make sure the connection is good, and no broken wires.
Howdy Keith, The heli DVD is not ready just yet, we had to put it on hold to release the 3D Throwdown 2006 DVD first. I will be in vegas this weekend for NAB, shooting a film all week, and then shooting the 2007 3D Throwdown in vegas with the Flying Cirkus club.

I'll give all of this a try. Thank you !!!!

So what's the word on the street Kyle? :D
Didn't get a chance to play with it. I should get around to it by 16:00 today.
So the senser is analogue (x) and not digital (*). I started to fly with it off, and it flew great. Hit it up to 80%, and all hell broke loose. Ailerons went crazy. I flipped it off, landed fine, changed my shorts, and put the heli away.
This was just 20 mins ago. Does the sensor only work during the day? I was on a small residential street, about 4 cars wide. Would that cause the sensor to go crazy?
Test two will be Thursday afternoon.
Thanks everyone,
Kyle

Since your at NAB, stop by and say hey to Gary Travis. He's in one of the booths along with the Turbine Observer!

Yes, the sensor is analog.

Kyle. What happened to the ground test? Last post you had, you cranked the gain up, and said you saw no response from the sensor.
Did you change something to get the sensor to respond?
You need to make sure that on the ground, the swash tilts away from your hand as you move it around the sensor eyes.
I would also not jump up to 80% directly. Slowly dial in the gain and watch the results.
Did you calibrate before takeoff, or in flight or at all? Maybe you had a calibration in the house or something that was drastically different from your flight conditions?
This was just 20 mins ago. Does the sensor only work during the day? I was on a small residential street, about 4 cars wide. Would that cause the sensor to go crazy?
No, sensor will also work at night. You can ring this thing out in your house. I would not fly it again until you know it is doing what it is suppose to.
If you have calibrated it at all, I would go to where you want to test it at, (house, garage, etc...).
Calibrate using the cal feaure.
Crank up the gain, then move your hand around the sensor, and the swash should tilt away from your hand.
If that all works, then take it outside, stand behind the heli(out of the sensor's way), and cal it again.
Your sensor is mounted in X position not + position right? Stabilization is turned on as Stab IRX right?

I knew there would be at least one booth I would like to see. I am tied up filming at NAB, and then some booring post NAB meeting this weekend. I won't get a chance to visit.
Thanks for the help.
I changed the sensor to analog from digital and it started responding. I calibrated about 10 feet up. I'll try a lower setting tomorrow.
Thanks again!!
