Too new at this, please help

I recently became fascinated with r/c helicopters so I have bought a Blade 450X.... Probably not a good idea for a brand new pilot but its mine now. I've learned alot in the past few days on how this thing works after I crashed it twice. Long story short, I was re programming my receiver (ar7200bx) and now the servo up front will not respond to the servo centering part... It either runs the swash all the way up or all the way down... there's no in between. The other 2 servos react as they should by twitching and allowing them to be centered. Any idea what this could be...? Its a brand new servo.

Welcome to this forum. There is a specific 450X forum here, lots of people still flying the 450X..
To answer your question... the servos have plastic gears and strip vey easily when crashed. To check gears, with power off rotate servo arm, it should feel smooth and no clicking, next check the servo arm itself. In some crashes, it can rotate on the servo, stripping the mesh. Causing misalignment. If so then you need a new servo arm.
Also check the push arms from servo to swash. They should be straight, and snapped on.

Welcome! Many of us learned on 450's, you can succeed!

If you don't have a computer simulator, grab one and use it. Find a heli pilot to help on the setup/repair and join an AMA club in your area, both are great ways to learn the ropes.

You found the best site for forum help. Search and read, then ask if you still have questions.

Set the swashplate to normal on the beastx. If you set it to 120° the servos will not work properly... pretty much do exactly what you're describing.
Good luck

Are you saying it's a random thing when you initialize that the servo might end in a up or down position.
