Good evening, I am about to start a 250 build and your videos are great. A couple of questions if that's ok? When you remove the servos after centering with radio and you disconnect from receiver to fit balls onto horns do they stay centred? Also can you show your finnished cable routing and how to shorten cables?
Without power and receiver signal, the servos will move if you push on them. You have to be careful not to do that. When you put the horns back on, you can power them up and go back to your 50% pitch point, and it should be easy to see where they need to go. My wiring job isn't that good - you can see some good ones on Helifreak web site. I will do a video about shortening the cables when I get around to it. That has been requested and is in the queue :)
hope you don't mind jasmine, your vids are always of great help. This is just another way to do it:
If you have difficulties follow jasmine's way, i found this way to be easier:
First connect the Boom to the Mainframe with the Belt attached to the Tail drive gear, than simply slide the Tail Rotor Shaft into the Belt slope and built the Tail unit around.
Pull the Boom a bit to give the Belt the right tension (don't overdo!). Fix screws - done.
Jasmine,

Yup - any way to get it on there correctly will work. I did a similar way when I recently switched to the carbon fiber boom.

The Trex-250 is not very good for beginners. It is very small and fast, and the setup can be hard to get right. However, it does have cheap parts.
