This is, by the way, how my board looks like from below. Beautiful chaos... but still functional. I am planning to make a PCB soon...
Some thoughts on FPV camera tilt compensation
Almost every 'serious' FPV racer is tilting the FPV camera up in order to have a better image during fast flight. Angles between 10 and 35 degrees seem to be common. E.g. I am using 25 degrees. But tilting the camera with respect to the multirotors horizontal plane has a side effect on the controls (maybe you never thought about it, because you are so used to flying with this side effect). Just to make the effect easier to visualize: Imagine you drank a beer too much and now you suddenly think you are Charpu , Mr Steele or Mattystuntz . You mount your FPV camera with 90 degrees tilt (pointing up vertically) because your best friend told you that all the pros do it like this. In this case, your roll and yaw control will be interchanged: When you move your RC sticks to roll left, your copter will roll left, but looking through the FPV camera, it appears as if you are yawing to the left! And if you move your RC sticks to yaw left, your copter will of course yaw left, but the im...
Hi William, this is simply awesome work that you have done here. I like your tricopter multi-layered chassis very much.
ReplyDeleteOne thing I am wondering is why do you need to use your TriGuide program? If you use three rate mode gyros for the arms and one head lock mode gyro for tail server, wont that be sufficient to have the tricopter run stable? If I understand correctly, you are using the triGlider basically to make your aircraft more stable? Forgive my ignorance if I missed reading something in your post.
Hi Sid,
ReplyDeleteyes, I think my custom software makes the copter more stable than standard RC-gyros can. Additionally, I have an accelerometer on board, so the copter can hover on it's own. This in the future I can also add features like GPS etc., that won't be possible on a copter without custom electronics..
