[diamondback_hydros]

i just rebuilt a cp and when i give throttle the collective is reversed. anyone know what the heck happened. In other words when i give throttle the the pitch goes negative. compared my setup with other pics and its the same as far as i can see.

thanks in advance

On the Tx there are reverse servo switches on the bottom. Off the top of my head the first thing I would check is those. The manual will tell you which ones are reversed. On page 19 it says that Ele and Rud is reversed. I would check to make sure those are reversed and the others are not.

If that is not it let us know, sounds interesting if not.

Thanks,

Are you still using the E-Flite servos on your rebuild? :?:

i am using eflite servos. the swash moves up but gives negative pitch.

That's correct then. Swash moves down , pitch goes up. Normal!

I am literally rebuilding my BCPP now. I spent a ton of time working on the head when I buitmy TRex. So I figured now, while it is fresh in my head, to rebuild my BCPP head. The first thing I noticed is that the pitch is different. Up gives positive pitch on the TRex and gives neg pitch on the BCPP. The engineering just blows my mind.

So is all good?
