I have 2 CX2 versions:

1st version - all Xtreme - Xtreme tail boom, skids, canopy, CNC blade grips, Upper extended rotor, Xtreme blades, and the 180 stock motors, all eFlite aluminum except for the upper rotor hub, vortex fly bar

2nd version - all eFlite aluminum, stock front canopy, vortex plastic grips, Xtreme blades, Boomtown tail boom and unbreakable skids, stock OEM motors (much more agile and quick)

Both fly very well and hover like champs. The swash plate is level with the control rods in the 3rd position. There is absolutely no TBE. I have even move the electronics around have equal weight distribution left to right. However, when I want aggressive forward flight, they both fly a bit sideways and to the left. It looks like they both lean down and to the left when I apply forward elevator. However, I can get them to fly perfectly straight and level with the nose pointing straight if I also apply a little aileron to the right.

Is this normal because of the way the swash plate is set up of can I adjust some of this out with either the proportional mix or gain?
