"@ Murray .... have you ever thought about using a magnetometer external shielded with mu-metal? I'm waiting for the components then i place the results."

"22% ? Wowwwwww i have 83% of EM interference....is dangerous???
The quadcopter fly very well!!......What are the Jeff motors???
Thanks"

"......but who wantso try !!!??!?!?!?!?

MOTOR 1 

MOTOR 2

What do you think?"

"Hi, Murray knew this drone HALO ... but do not know how to design the removable arms .... I think about it for a long time!!

"Hi,Why do you think the 360Kv brushless RCT are not good or are of poor quality?For the price maybe?See here and especially the price! What do you think?bye

"I think that the motors from 360 kv to rctimer are the best compromise between price and quality performance.I also think that there would be a great way to create a frame to Y6 using the same motors.What do you think Murray?"

"like this!!.....   prop mount   but the shaft diameter is too large of the propeller hole!
I think that is better to save a drone with a screw..... rather view it it goes down!

Goooooood idea!!! very nice landing gear.

With yours monting props certainly get worse the vibration on video-camera...or…"

"It is for me, your first project is better, but to fly through the branches of the trees is what is needed small propellers.But with these engines and propellers, the flight time is really a lot!it is true that if I raise the propellers get greater…"
