Attention! If you’re using the New DFC Rotor Head please read below.

First of all thank you for using Align official upgrade parts on your Trex helicopter.

Regarding Align’s recently released 700DFC rotor upgrade assembly, there has been an instance reported by 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 starts. 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 been 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 of the local distributor to exchange the newly designed screws and grips. This replacement process will start on January 22, 2012. If you have any questions, please contact your local distributor.

You can identify the first version and the newly designed version per the attached announcement.

Best Regards,

Jeff Fassbinder
Director of Marketing

I am going to get one of these but I am concerned that I will get the old design and then I will have to go through the process of having to get the replacement parts. Will Align be upgrading the sets that are on the vendors shelves or will the consumer have to go through the process his self?

I see you stated something about a 600DFC head, I am yet to see it. Where can that be purchased?

600 DFC head is out. The grip linkage and bolt is the latest version. You can try my local hobby shop RcDepot aka They had a few left as of this evening.

If you purchase the 700 DFC head. Make sure it ends with the letter A (H70089A)is the updated version.
