I'm a bit of a newbie with this stuff... But I'm trying to set up my wife's HoneyBee CP2. The very first thing I did was unplug the motors from the 4-in-1, turned on the tx, and plugged in the heli's battery. I played with the controls to make sure that everything was operating correctly. And the servo on the left side is not.

Without power, the servo arm is in a good position, as shown.


But when I plug in the battery, the 4-in-1 calibrated itself, and in the process that servo arm rotated to this position and was stopped by the frame.


I can hear the servo trying to rotate even more, but it can't because of the frame.

I did a little playing with things to no avail, and I'm not sure of how to proceed. I *think* that I should remove the servo, remove the arm, and then replace the arm at a lower angle. Yes/no? I'm just not sure and don't want to muck things up even worse.

Any help would be appreciated.

Thanks,
Scott

Hey Scott,

I would open the servo up first. Look to see if the gears are not broken or stripped. [link=http://www.youtube.com/watch?v=fmrTPEfc-3M&eurl=http://mysite.verizon.net/bizwptdb/id29.html]Here is a video you can look at[/link] to help with taking the servo apart. Next, since it is not specified in the video, is to make sure that the 2 little plastic stoppers on the top servo are facing at 5 and 7 o'clock. While looking at the open servo, the big gear will be at the very top, the stoppers will be facing down and at 5-7 o'clock. The stoppers look like this-> / \ . If they are off line, it can and will cause the servo arms to center in the wrong place and or not center at all...When everything is back together, apply power until everything initializes and then put the servo arm on the servo at 90 degrees from your linkage.

Hope this helps...

I did a little bit more testing, and one thing I tried was to switch the connectors around on the 4-in-1. As it turns out, any servo that is plugged into channel 6 exhibits this strange behavior, and any servo plugged into the other channels works fine. So it's not the servo, but seems to be the 4-in-1.

Could this be caused by a bad gyro gain or tail gain setting on the 4-in-1? If not, any other ideas?

I should mention that this heli has never been flown. It was powered up once, and my wife could not get it to lift off the ground. I finally got some time to look at it, and this is the first thing I ran into.

I hope someone else pipes in soon. I don't know much about the 4-1's. I have rebuilt and re-soldered many servos to save them though. If it is a never flown machine, do you mean brand new? If so, Maybe you should return it/exchange it?

Sorry, I could not be of more service.

Good luck,

the gain or proportional (gain affects the built in gyro and the proportional controls motor output) will have nothing to do with the swash plate servo controls. that is purely a servo control issue. it does sound like the 4 in 1 is bad or the ccpm mixing software is screwed on the controller.

just to be sure, make sure all the servo connectors are plugged all the way in. check that the radio crystals are snug on both receiver and transmitter.

Maybe you might already know this fact.............Try not to coil or bundle the antenna. Have the antenna in a continous stream.
And not in contact with metal. This is to avoid signal interference that might effect the servo.

Well it turned out to be the tx DIP switches that control CCPM mixing. She had played with the tx on a SIM so flipped the switches, and simply forgot to switch them back. All is good now.

LOL....Glad you figured it out...Now you can fly it while she is out shopping. Just don't crash it into the fish tank. Hard to explain all that water damage. ~True story from a buddy flying his friends CX2 while he was "away"..
