Hi,

I have a quad that is 4.7 lbs (no camera yet, I will be installing a Hero HD and FPV)

I am looking for a more reliable motor replacement  

What I had: (Sick of working on them)

APC 12x3.8 Slow Flyer
TR2217/20 Turnigy 2217 20turn 860kv 22A Out runner
TP_w25A Tower Pro w25A Brush less Speed Controller

Motor distance is 51cm

Motors have ripped apart more than once.  Now I will not touch them.

ESCs cal at two different speeds, 2 start faster, and two start later. It works if I arrange them fast front and back, and slow right and left or vice versa. They just act different, even on a test bench.

Oh yea I have no idea on motor sizes, how many turns I need, and  prop size.

Thanks in advanced for any help,

Scott
