MegaPirate: AltHold, Loiter and RTL with an Octo

by tecdux | April 28, 2013 | (5) Posted in Reviews

I've been using Multiwii but i wanted to test MegaPirate, so i uploaded the code and probably i'll never come back to Multiwii :D

Very stable flight with a homemade Octo with Crius AIO Pro. Testing Altitude Hold, Loiter (AltHold and Position Hold) and Return to Launch, great performance! I tuned the PIDs for Rate Roll, Rate Pitch and Stabilize Pitch, all other PIDs are default.

No software stabilization used in the vídeo.

I carried a GoPro and the video recorded by the octo was very stable! :)

If you have a Crius AIO Pro, I highly recommend MegaPirate!

I am curious to know why one chooses an octo copter rather than a quad or a tri. Fewer motors means less battery and therefore less weight and more flight time it would seem. But maybe with the octo it is maybe more stable or there is less stress on each motor. I don't know. If you don't mind, please explain why you chose 8 instead of 6, 4 or 3

I agree, quads are simpler to build, cheaper and smaller but there's just one big problem: reliability. If one motor or ESC or prop breaks you will go down.
Hexacopter and octos have motor redundancy so they can keep flying (or at least allow you to land). I've build a hexa but the with one motor out the flight was very critical, that's why I chose the octo ;)
