"They are connected....parallel.........so they drain equally"

PeteD commented on Felipe Jaramillo's blog post QuadRotor Project, Part 2"I see you have 2 batteries. Are they each operating the 2 motors independently or is everything connected? I guess what I am asking is the quad setup to ensure that both batteries are drained equally?"
Felipe Jaramillo commented on Felipe Jaramillo's blog post QuadRotor Project, Part 2"Sure, you are right. In order to keep the overall thrust constant, one pair increases speed and the other decreases in the same magnitud"
palo sestak commented on Felipe Jaramillo's blog post QuadRotor Project, Part 2"Well its logical (after i turned on my brain and tried wikipedia :o), but one thing i can't get out of my head: when first or second motor pair changes its rotation speed second should do opposite action, otherwise overall thrust will be…"

Hi, the yaw movements is caused by the torques generated by the rotation of each motor. The front and rear motors turn in one direction, and the left and right in the opposite direction. So, by controlling the motor speed of one of the pairs…"
palo sestak commented on Felipe Jaramillo's blog post QuadRotor Project, Part 2"Perhaps i'm bit uninformed and the question is too easy but i'll ask:
How is the yaw control performed? I don't see any motor tilt mechanism..."
Felipe Jaramillo commented on Felipe Jaramillo's blog post QuadRotor Project, Part 2"Hi, thanks for the comments.
I did the extensions because the wire that came with the ESC was a bit short, so I soldered the extension and used some heat shrink on top.
The weight of the vehicle is about 1Kg.
Here is the link for my previous…"
Ground Loop commented on Felipe Jaramillo's blog post QuadRotor Project, Part 2"If you're good at soldering, a well-done wire-to-wire splice is probably lower risk than resoldering onto the PCB. I've done both, and unless you want to change the wire gauge, it's probably not worth the risk and extra work of…"
SciFly commented on Felipe Jaramillo's blog post QuadRotor Project, Part 2"Looks great. Whats the total weight? Can you provide a link to the previous post? I notice you have soldering extensions on to you're ESC wires. If you are comfortable with SMT soldering, You may want to consider soldering extensions directly…"

Some weeks ago I posted about my quadrotor proyect and showed a video with the Roll controller on a testbench.Now I'm working with the yaw controller. I build a simple testbench to test the behaviour of the controller. As I said before, I am implementing a digital PID on the arduino MEGA, and I use Labview just to send the commands and visualize the behaviour of the quad.Here is a small clip of how the yaw controller is working right now. I still have to improve it, but I think I'm getting…See More
Felipe Jaramillo left a comment for Ah Bao"Hi.
I have done several projects with LV. Please let me know exactly what kind of information you need, and what project are you working on so I can help you."
Richard Hirst commented on Felipe Jaramillo's blog post QuadRotor Project"Hi Fab.. I have now calibrated the ESC, fitted smaller props.. and had an excellent 10 min flight :-)
Well do to all who has been involved."
Ah Bao commented on Felipe Jaramillo's blog post QuadRotor Project"Hi Felipe Jaramillo
You have done a lot of projects with labview right. May I know what kind of labview base projects cos I am final year EIE student and I need to do one labview base project. Right now my mind is totally blank that's why I…"
Roy Brewer commented on Felipe Jaramillo's blog post QuadRotor Project"Öncü,
That video is of ground resonance, where articulated rotor blades interact with flexible landing gear to produce catastrophic results. Very few quads would be susceptible to this.
Ground effect makes the prop able to lift more than…"
Roy Brewer commented on Felipe Jaramillo's blog post QuadRotor Project"I am certainly looking forward to hearing details about the prop design.
What's wrong with the current crop of available BLDC motors? Why did you feel the need to design new ones? (not that I'm complaining)

"They are all made by our request. I did contact also RCTimer and others but they could not offer what we wanted to have. Prop molds are made especially for us. And currently we are finetuning those with a factory. Having small balance issue with CCW…"

I have started my quadrotor project.
Im using the mikrokopter frame with some additional center plates and a few modifications.
E-flite motors, with E-flite ESC. An arduino MEGA board. A Vectornav VN-100 which includes…

Contests
Season Two of the Trust Time Trial (T3) Contest has now begun. The fourth round is an accuracy round for multicopters, which requires contestants to fly a cube. The deadline is April 14th.A list of all T3 contests is here.
