I built a mini drone a few weeks ago and have just gotten the time to look at a weight issue I’m having. I’m pretty sure the issue stems from the weight of the speed controller, which I built myself, and also of course my lack of understanding of aerodynamics.
I could reduce the weight of the speed controller board by piggybacking the Quad Half H-Bridge IC to the back of the XBee board and discarding the rest of the weight there. I am curious though as to what I should do to reduce weight further, as I also wanted to add sensors to this quad.
Nice little quad, what have you use for your base ?
From my point of view, you don’t look to have the propeller right. The should be the opposite from front and back.
You can use ecalc but not sure with such small UAV
I’m kind of experimenting controlling the quad from my PC, as I want to create a mobile sensor network from them.
The grand plan is to have 4 or 5 of them flying around and communicating with my computer using the XBees. In testing I can control each motor separately to create directional movement, so I can send a power-off signal to 2 motors for a second to cause the quad to move in that direction.
All the theory looks sound, I’m just still a novice when it comes to actually getting the quad off the ground.
