Hi folks

Hopefully someone can riddle me this...cuz I don't get it. And maybe there is nothing to get, but I thought I'd ask...

Everywhere I read about how important it is to have nice square linkage connections. And how important it is for the tail servo linkage to run parallel to the boom, nice and straight, etc.


So why does my heli (a HeliPro Black Hawk 450SE) and others features a tail servo linkage stabilizer mid-boom which snaps the linkage at the center of the boom? If the linkage is attached at this point (presumably to reduce flex) then it is not possible for the linkage to be parallel with the boom since the linkage connects to a point offset from the center (the tail rotor slider arm connection point).

So if one uses the mid-boom stabilizer thingy then the linkage HAS to be diagnonal along the length of the boom, and not parallel.

So what am I missing? Should I toss this mid-point stablizer of the tail servo linkage which would allow me to mount the servo such that the linkage is much more square and parallel with the boom? Will the linkage then bend? Are there aftermarket linkage stabilizers that I could use? How is this being solved?

Or is it a non issue, and I should stop concerning myself with this level of tuning perfection?


Here is a pic on Ka-plane's site of the BH450SE... notice how even as-new the boom is flexing:


Now that I have my S9650 dig servo installed I was able to eliminate the "bowing" of the linkage that you see in the pic. But I am unable to get the linkage completely "aligned" and parallel with the boom due to the linkage stabilizer/tail boom mounting point you an see at mid-boom. It stabilizes the linkage by snapping the linking into a slot, where it is held loosely to prevent flex and binding. But when snapped in the linkage is centered on the boom. So now what?

Thx in advance
