CX2 - Flying FAST
Wow. I just moved the servo links to the third hole in the servo arms (for both pitch and roll), and the model moves FAST.
It's hard to believe a coaxial can do this. Yes I have all the CNC upgrades and none of that really makes any difference except perhaps the swashplate, which now has some serious deflection due to the long servo throws.
Flybar is stock. No blade strikes yet.
As expected with a coaxial, you need to 'surprise' the flybar by pitching the heli quickly forward to get it going fast. Eventually it will start to slow down as the flybar does what it is supposed to do (stabilize the model)... but a way around this is to punch it with more power and ascend. It will deflect the flybar such that foward speed can be maintained.
I also upgraded to Tenergy 900mAh 25C and Lighting Power 850mAh 15C batteries. They deliver a lot more current than the stock batteries. I would never get the stock batteries again.
The other upgrade that really made a difference are the Extreme 180 motors. Ball bearing, heavier magnets, better ventilation, replaceable brushes.
To aid in cooling I cut the nose off the body so air can pass through.
Anyway, I am very impressed with it's performance as a non 3D helil.\
I will post a video soon.

RE: CX2 - Flying FAST
I can wait. I just broke the tail off of my CX2 when the roof got in the way of my flying fast practice. Our CX2 birds have the same motors and Tenergy batteries, but most of my running gear is plastic except for the CNC upper inner shaft bearing cup. The inner shaft is a Supershaft and the upper rotor head is extended for less blade strike. The linkarms are in the second hole and the flybar is not stock. It does better in wind with that setup without acting so squirrely that it becomes a poor camera platform. I thought it could go pretty fast. Must have, since I only had time to chop the throttle when I saw the roof jump in its way. Supershaft did its job, however. I expected all sorts of broken and bent bits, but only broke the tail. Should be able to fly again when the glue dries.
