-{{ :rc:files:microquad:microquad2.jpg?direct&350|}}
+<note important>This quadcopter was dismantled on 27.10.2012 after 26 flights since is became clear that is wasn't possible to make it fly without constant vibrations even when using high quality motors. The reason appears to be weak quality 4x2.5 propellers and lacking rigidity in the frame. Replaced with [[rc:crab-20-quadcopter|Crab 20 Quadcopter]].</note>

-===== Lessons learned =====
+===== Notes =====
+  - Always check that motors have been assembled correctly, the C10s had the screw holding the mount in place misaligned resulting in one flying motor during first takeoff
+  - Use threadlock in the tiny screws holding the motor in the mount
+===== Motor benchmark before build =====
+The following motors were tested before starting the build:
+  * C10 2900KV with 4x2.5 prop (HobbyKing)
+  * BC1410 3500KV with 4x2.5 and 5x3 props (RCTimer)
+  * BC1410 3900KV with 4x2.5 prop (RCTimer)
+    * found to be not suitable, probably better with a 3" prop
+{{:rc:files:microquad:motortest.png?direct&400|}}
-  - Always check that motors have been assembled correctly, the C10s had the screw holding the mount in place misaligned
+The result is that C10 has better efficiency than BC1410 and it's the better option even as somewhat heavier.
