Im Guillermo from Cordoba, Argentina. This is my first quadcopter project.
FUTABA 2.4ghz RC
4x 28-26 1200Kv motor
with 11x4.7 propellers.
flew. but also crashed. Not if I'm using very large propellers, or have a bad PIDs. the quad flies with only 20% throttle. And I think when the rudder corrects problems appear. In the first flight of flying to 10 inches from the floor, suddenly lift up and gave a flip and then fell to the ground. Where I can start modifying the PIDs, or directly buy smaller propellers?
Regards! thank you very much for all info in your site.
