Firmware Update   |  33

 

A motor shaft might be slightly bent or a propeller is defective resulting in vibrations.

Either replacing the complete motor arm or installing a complete new set of propellers

may solve this issue.

 

Crashing the Navigator 250, or exposing it to mechanical stress during transportation

typically causes these phenomena.

 

The onboard sensor has lost its factory calibration. Typically, this is caused by a hard hit

(crashes), or exposure to high temperature. It can also be related to transport issues.

 

An easy way to maintain the Navigator 250 perfect condition is through visual inspection

after every crash.

 

During a crash, a motor and arm may be broken. Even if the Navigator 250 is not

noticeably damaged at first sight, there may be minor cracks. Such cracks can put the

propeller out of alignment with the rest and make the Navigator 250 unstable. Besides,

cracks can lead to other problems. Always check the Navigator 250 carefully for cracks.

 

Ensure all screws are securely tightened. Replace parts with worn out or stripped screw

holes immediately.

 

If a propeller is damaged in a crash or other action, replace it immediately.

 

This also applies if there are fine tears or grazing in the propeller. Due to the high

speed, parts could become loose if the propellers are damaged and result in product or

property damage or personal injury.

 

Replace damaged propellers according to chapter

‘14.6 Installing the propellers’
