I purchased a Blade CX about a month ago, and by no means am i a pro at flying it yet but i've noticed that no matter how much i try to trim it, it always rotates to the left. Any thoughts on this or a way to fix it?

Could be you need to adjust your "pots", or you have a bind in one of your shafts. Making it slower for that blade, and making the yaw happen...

Hope this helps,

Also check gear mesh. Not to tight. Everything must work freely together, and good to lube up some of those crucial areas also....Tri-Flow, or some gun oil work great.

make some adjustment to the proportional setting on the 3 in 1 and you should be good to go or like Jeff said you could have some binding somewhere

I have never lubed any part of my CX2 - should I? it's had lots of flights and I have a bag of broken rotors to prove it. Those crashes were due to me learning to fly at first and then learning to fly outside in wind. I'm starting to get it too but still shatter the occasional blade due to mid-air blade strikes. I would like a bit more info on lube though - please expound. As to the yawing tail - it's almost got to be the proportional trim pot.

Thanks for the tips

Tri-Flow is a popular favorite by many including myself. You can get it in the can or the tube. Local hardware store is where I got this can. My LHS carries the tube stuff. I get good results with some gun-oil to... You don't want to use any lubricant that will attract dirt however, or you'll cause worse damage by more friction from the dirt particles. I've used silicone before from my RC-Car stuff, and that stuff did exactly that. It wore the parts quicker. It's a good habit to periodically clean all your lubed bearings and parts, and re-apply fresh oil from time to time.

Hope this helps,

Remember to start at the beginning;
Is your upper rotor tracking properly? That's a HUGE deal. IF it isn't tracking, adjust it.
Does the flybar run true without vibration?
Does the lower rotor track true? If not, follow the tips in the CX posts to get the blades to track. Boiling them will probably make them better.
If you spin just the lower rotor is the balance good or does the heli shake?
Of you spin just the upper rotor is the balance good or does the heli shake?

When everything that spins is true and smooth, THEN worry about getting the pot adjusted. If you use the pot to compensate for a chipped blade or balance issue or tracking, every time you change a blade or anything else, the pot will need to be adjusted again. Use the pot to clean up a very very well adjusted helicopter and you won't touch the pot for the next 50 flights. If the rotation changes after a mishap, it's 90% likely that the problem is mechanical - not the trim pot.

I hope that makes your life easier.
