Good point chopperdudes,

I also have found the screws in the mixer arm do matter on flight characteristics.

Just got done adding a shim at the o-ring. Up-downs still there. I can fly it this way, but I know how solid my regular CP could hover, so that is what I am aiming for. I am sure the up-downs are costing me a little in total battery-flight time also.

I know that once the up-downs are solved, this heli is going to be very smooth. I have my throttle and pitch curve matched well on my radio. I have a dual tail set up, which is holding the tail very nice. Obviously not a good as my Rexy, but pretty darn good for not having a HH gyro. In no way I bashing Horizon or the CP. These helicopters fly very nice when you get them set up well.
