I was thinking about upgrading from my old APM 2.5 to the new Pixhawk and was curious if that is the right route for a large Helicopter platform? I kept seeing people finding some bugs in the system…Continue

APM2.5 3.1 servo twitch

I recently upgraded to 3.1 on a trex 600 running digital servos and I am getting a random twitch. I thought at first it was the ppm encoder so I re-flashed it like I have done before on other APM…Continue

Has anyone tried integrating a slip ring onto their gimbal? I am currently running a photoship one gimbal and the APM is controlling the servos.My frustrations about this is that I can only turn the…Continue

Looking into getting a Sony NEX5 camera. I would like to have control over the zoom feature. Has anyone played around with a controller that can do this over a link? Maybe even have a 3 axis…Continue

3DR Pixhawk

I was thinking about upgrading from my old APM 2.5 to the new Pixhawk and was curious if that is the right route for a large Helicopter platform? I kept seeing people finding some bugs in the system and wanted to know if those have been worked out? On another note does the Pixhawk have more input and outputs than the APM2.5? I ran into a problem with the APM as there are not enough inputs to outputs. If I control a gimbal with a joystick I would like to be able to use all 3 axis's. All comments…See More

Dear Sean Whitney,

I saw a video from your Trex 550 in Loiter Mode. The heli is staying very rigid in the air.

I'm using a TREX 700E and want to fly this heli with apm 2.5 version 2.91 autonomously.

Currently I want to adjust the PID parameter. The stabilize and the Altitude Hold Mode is working perfect, but I have some problems with the Loiter values.

So would it be possible to send me your PID values of the loiter mode? I think they have to be very similar.

Thanks.

Nice Greets from Austria

Manuel
