Regarding Align’s recently released 700DFC rotor upgrade assembly, there has been an instance reported customer where a loosely tightened bolt on the pitch link assembly caused high frequency vibration, resulting in material fatigue and bolt breakage from where the thread start. Due to the concern that this breakage can lead to unforeseen safety issue, Align has modified the grip linkage arm design of both 700DFC and 600DFC rotor upgrade assembly. In addition, the bolt has been replaced with one made from CNC’ed high carbon steel material for improved rigidity and strength, effectively avoids bolt breakage issue. Caution: Please do not fly before the 700 DFC new parts have replaced. We deeply apologized for all the inconvenience caused.
For customers who have already purchased the first version of Align 700DFC head upgrade set, please bring the main blade grip arm and the screw to where you purchased or the local distributors to exchange the newly designed screws and grips. This replacement process will be start on 2012/01/21.
If you have any question, please contact with your distributors or mail to email@example.com
