I have always had some problems with vibrations on my APM quadcopter. This is because my homebuilt gimbal was not sturdy enough. This is an attempt to make it better.

My new gimbal that I have built has a ball bearing on the opposite side of the tile motor, making the entire construction more sturdy. I have also built this one out of thicker plywood to prevent the wood from flexing as mush. As can be seen in the video, the results are pretty good, but there are some vibrations when a fly fast forward. Maybe this is because I still have the roll motor mounted the the fuselage using an old 3 mm plywood that can bend slightly. At the end of the video, there is a crash. While I rapier the quad I will try the make the gimbal even better.

A new video of some flying with my APM quadcopter. The newly installed LEDs impoves visibility a lot. The video was shot on new years day. The weather was cold and the wind speed was high, about 10 m/s, but the Ardupilot in GPS assisted mode makes it easy to fly even in those conditions.

A new compilation video made with the quadcopter. During this summer I have flown this quadcopter for a total of about 6-8 hours. This is the best of those flights. I have also stabilized almost the entire video in post production to get rid of the small vibrations. The entire video is shot at my local flying club Gamen.

This is a small quad I built using the motors that was lying around after the hexacopter project. I wanted a small maneuverable quadcopter to do flips and just fly around with. This one is not designed to carry any cameras, and it is made to be durable and easy to repair.

This is a compilation of some arial video I have recorded using my APM quadcopter at my local flying club Gamen mfk. Some parts of the video is FPV flying and some parts visual flying. Most of the time I fly in loiter or stabilize mode. Read about my APM quadcopter here.

This is my latest multirotor, the APM quad. Equipped with the Ardupilot, it is full of features. Its also lighter, more reliable, and more efficient than the hexacopter.

This was my APM-powerd hexacopter. Unfortunately this configuration turned out to be problematic. It is now retired, but I did learn a lot of things from it.
