stm32 is a 2$ arduino due 19 $
, i cant use servo library with virtual wire library because they both use the same timer (timer 1)
and when i did so there was a conflict .
this is an under contraction code , and i copied the post while i was working on it thats all
so it is
 myservo1.write(esc_1);
 myservo2.write(esc_2);
 myservo3.write(esc_3);
 myservo4.write(esc_4);
