Tricopter - Tail Servo not function

Posted by Ross on January 28, 2012 at 3:53pm

I have the APM 1.0 on my tricopter. The latest tricopter firmware was downloaded today.

It seems the motors are working correctly. IE: They respond to input from RC Transmitter and seem act correctly as the tricopter is tilted.

I cannot however get any movement from the tail servo. When looking at the APM Planner -> Radio setup it is reading my rudder input from the RC TX...the servo just isn't doing anything.

I read a couple other people with this issue...however they were able to get movement when in manual mode. The firmware I downloaded today...does not have manual mode.

I checked all the connections against the diagrams think it is correct. The servo is connected to 7 on the APM

Does anyone know how to fix this or point me in the right direction?

Thanks,

Ross

    Ross, (or anyone else with a Tri), can you have a look at this issue and see if you can replicate it on 2.3? I would do it myself but I'm not near my equipment.

    I had pulled fresh 2.2b6 code from GIT last night right before the version increment, and still had the problem. I'm unsure if I got it before or after the changes committed by Pat, but looking through the code changes I don't see anything relevant to channel 7 out. (maybe I just missed it?)

    It flies. Its very windy today and she didn't like it that well. It seems the gyros are a bit too sensitive for high winds. She did real good close to the ground not as exposed. Burned up a whole battery with no issues. The tweaking begins.

    Any chance you could point me to a good tricopter config file?

    There was a bug for ticopter yaw output in 2.2b4. It's fixed on the GIT if you can download and compile it with arduino. If not, a new realease is due out very soon.
