450x pitch,

[honwal]

Just got my 450 back together after a crash over w/e, replaced main shaft, blade shaft, main gear wheel, elevator arm, anti rotation bar, align blades replacing stock blades, all the servos centre at 90 degrees, when I put on pitch gauge, I get a -10 at 0 throttle and a + 12 at full throttle, the settings I have in TX gave it a pitch of low stick +3 to +7 at high stick, I have rebound 450, my thinking was once the settings were in they would have transferred to 450, one thought was to reverse pitch would this work,.....it was in manual to reverse pitch and rudder,
any Ideas,

You should not change anything in your TX - those settings will remain the same. If you need to reverse any channel in your TX, you've done something mechanically wrong.

The one that catches most people out with teh 450x is that the pitch links are TRAILING EDGE. That is to say that the pitch rods to the blade grips should be behind the grip in the direction of rotation (meaning swash down = pitch up!). Most helis are LEADING EDGE, causing the confusion.

Assuming you have put it back together correctly, what you haven't done, and you need to do, is recalibrate the servos in the BX - in particular menus G,J,K

cheers tom,
I found where I went wrong, I thought what did I do different when I initially set up heli in first place the only thing I could think of was I disconnected the main motor, this time after repair I tried with throttle hold on, so disconnected motor and hey presto back in business, had 450 back in the air tonight with hovering and a few left right runs,

Well done. It looks as if you are making progress.

cheers mike, it was so nice to be flying 450x again still cant believe how stable it is, just love the way it sounds, put different blades on, a third of the price of original blades,
