You will need to calculate lift over flight-time at operational altitude.

Yes, that will be the next step, controllibility first, then capability...

I crashed it after i "whiskey throttled" the collective. But im rebuilding now, fortunately tilt rotor with fixed pitch dont have all the expensive little parts that helis have.


Im hoping this among other sources will help me avoid saturation of the several integrals ill be maintaning... Link2

Good stuff! I see you're not using the wooden pole to damp oscillations any more. How did you get rid of that? From the pics it looks like you're dangling the battery pack underneath now.

First, as for the pole. Yes we've done away with it, now that ive pushed some mass out left and right, those rotational moments are slower and the gyro+math can keep up from the kk board.

second, hanging the battery was a huge help, and remember i said i was wondering if the CL should be well above the CG, well it pretty much has to be (a pendulum) or pitch changes are erratic or have no effect.

i like this more than my quad, as theres half the props, half the motors, and half the ESCs, so its cheap to fix. And a camera/sensors are easier to mount with better field of view than from a quad.

VIDEO!!!

You've just built a tiltrotor, you really expect me to believe you can't figure out how to upload some vids?

i can build UAVs, and plan to build spacecraft, but they still wont give me a degree in EE!

You don't need a degree in EE to operate a GoPro! Vids or it didn't happen smile

PS: You might need one before anyone will let you near a spacecraft.

Ha, if that was the requirement nothing would ever get built around here! Based on the number of connector jackposts that get twisted off, inspection mirrors shorting out battery cells, and ESD bags left over TC&R antennas I'd wager a HS diploma isn't even a requirement...


I propose a boycott of all of Patrick's threads until he posts video.
