Hi all. I'm new to helicpters and forums but been a plank flyer fir awhile.
Anyway, I'm having a problem setting up the head on my HDX450 SE V3. The links were not assembled on the head when I received the kit. I assembled and dimensioned the links per the HDX450 ASE V3 manual, page 17.

Following Finless videos provided with the kit concerning centering the servos to 90 degrees and setting the radio parameters as in the video, the washout arms were nowhere near parallel. In order to make them parallel I had to increase the length of the links from the servos to the swash to 54.5 mm (measured end to end). Finless said his measured 50mm. 54.5 causes the washout block to strike the bottom of the head when I give full pitch. Apparently this head is different from that in the videos. What gives? What are the proper lengths for all the links?

I've seen on Helifreak.com where someone else has the same problem. The link is http://www.helifreak.com/viewtopic.php?t=34837. This fellow set his links as follows: servo to swash-51mm, swash to upper control arms-48mm, flybar to washout-31mm, upper arm to bladegrips-27mm.

I'm about to try these settings but wonder why I've not seen any other mention of this problem with the HDX450 V3.
Helidirect doesn’t have an answer. Did anybody record their link lengths?
