Hi, nice work!
Did you use pla or abs?

Sorry, I'm a beginner... but I want to make this a nice and fast quadcopter. How do you think you would improve your specs for speed, using this same design. I mean... What would you upgrade from your quadcopter (to gain more speed and don't mess up much with battery duration)

Hello,

Firstly, the part that makes the quad faster is a higher voltage running to the motors. This is because the motors will spin more revolutions per second and create more lift. If you want this to be a better quad, I would recommend upgrading the motors, the ESC's, and the battery. I would also suggest getting rid of the gimbal on the front (simply not attaching it). The current parts list is designed for a budget but still descent quad. Also, I would like to add that the faster the motors spin, the more current they will draw, and the battery will not last as long. You will also notice that the battery I am using does not have a high C rating (basically how many amps it can deliver) so running too fast motors can hurt the battery.

For the motors, I would suggest the EMAX 2216 motors http://www.hobbypartz.com/66p-138-mt-2216-810kv-ccw-thread.html. They have a slightly lower KV (RPM per Volt) but since you are running them on a 4 cell battery with more voltage, they will spin faster. Any 30A ESC should work, these should be fine. http://www.hobbyking.com/hobbyking/store/__2164__TURNIGY_Plush_30amp_Speed_Controller_w_BEC.html.
And for the battery, something like this should generate a lot of lift. http://www.hobbyking.com/hobbyking/store/__9516__Turnigy_5000mAh_4S_30C_Lipo_Pack.html.

I hope this helps, if you have any questions feel free to ask =)

If I change only the battery and leave all the original parts, will it work better than with your current battery? I'm trouble finding the emax 2216 in europe...

The problem is, I am not sure if the motors I am using can handle 14.6 volts (4 cell). Also, the motors I suggested are really one of the top ones. Any motor from hobby king about 2216 around 800-900 KV should work.

For example: http://www.hobbyking.com/hobbyking/store/__67039__MultiStar_Afro_Combo_Pack_2216_800KV_and_Matched_20A_Afro_ESC_Set_of_4_CW_CCW.html

This is a nice set of ESC's and motors for a pretty good price.

could you please update the link for the Power Distribution Board? Or at least tell me the model you are using
