Really green question from a noobie - I'm building the Trex 450se V2 as my first copter and can't figure out how to attach the link on the linkage rod to the servo horn?? Hopefully the theory holds that there is no such thing as a dumb question.

There will be 4 metal balls somewhere in one of those little plastic bags, one for each servo.
Attach the ball to the servo horn with one screw and nut.

Before you do this go watch all of the Finless videos.

Tip....A pin vise works great for holding the rod while you thread on the first link. $7.99 at Sears with drills ..... or if you want machinist quality S162Z Starett Pin Vise set (around $55).

After chucking the rod in the pin vise, I heat it up with a butane torch lighter (hot ..... but not too hot) and it threads into the plastic ball link ends really nicely.

Here is another link to a site that sells R/C tools http://www.rjrcooltools.com/index.cfm
