Folding Props

NOTICE

Concerning the operation of folding propellers

Please, read the notice below before using folding propellers.

• Before assembling the blades, deburr the various edges and the root
• Balance the propeller when assembled
• The propeller should only be operated with an electric motor
• The maximum admissible number of revolutions may not be exceeded
• The value of the maximum admissible number of revolutions is printed on the packing label. For example "max.13000 U/min" means that the maximum RPM (Revolution Per Minute) must not exceed 13000 RPM
• Check before each flying session that the propeller is firmly fixed on the motor shaft
• Check before each flying session that the propeller is not damaged in anyway (visual check) and, if necessary, re-balance the unit
• Consider the need to replace any damaged blade or distorted center piece (heavy/crash landing)
• Ensure that the motor starts up slowly via a speed controller or soft-start. Alternatively, a resilient coupling should be incorporated. With sudden starts there is a risk of blade fracture and hence the dangerous risk of injury. Similar comments apply to rapid braking!
• After a crash or heavy landing - especially, if the blades were rotating, a fresh inspection should be made.
