D) Checking The Drive - Reely 1576770 Bedienungsanleitung

d) Checking the drive

Before starting the quadrocopter, you have to test the
drive. Only when all four propellers run smoothly and in
a perfect circle can the model be flown with the minimum
energy consumption. For this reason, you should check
the function of the drive propellers before each flight.
To do this, turn each individual propeller carefully with your
finger and check the concentricity and the ease of move-
ment.
When doing this, pay attention to the rotational directions
of the various propellers. Two propellers turn clockwise
when seen from above (A) and two propellers turn anti-
clockwise (B).
