Hey guys. I've lurked here for months before I finally plopped down the cash for a CX2. I've been fighting with it for about a week now, maybe 10 batteries, and have a couple of kinks left to iron out. Now that I've collected several, I can put them all in 1 post.

First, I almost immediately cracked the stock boom. I ordered a BoomTown boom and installed it with some new skids. The weight now seems heavily shifted forwards. With the trim 100% back, I sometimes still get forward movement. Anyway to correct without adding weight to the tail? The C of G is shifted forward when balancing.

Non-symmetrical rudder speed. It is clearly evident that if I go full rudder right, the heli does a fast pirouette. Full left rudder, and it's extremely slow. Partial throttle on the ground and test the rudder. Full right and full left. If I compare the speed of the top blade at full right vs the speed of the bottom blade at full left, the top blade is easily twice as fast. TWICE.

All around trim. Trying to trim it in is killing me and resulting in frustration. I understand the rudder trim will vary depending on battery charge. My problem seems to be aileron trim. Left-right trim seems also heavily dependent on battery. So is battery level supposed to effect all trim, or just rudder? It's frustrating as I reach the end of flight #8 and smile as I shut it down think that I finally have the trim perfect. Then power it up for flight #9 and have it shoot right HARD.

Battery is always installed on a stationary heli, flat on the ground and not moved until the light is solid green and the gyro has calibrated. I have adjusted the gain a bit. After I installed the CF Boom, I noticed the tail was twitchy left to right and back again in the air. So I decreased it, and the tail slowly drifted left to right and back again. Found a spot in the middle to stabilize. Proportional was not adjusted.

So far, I love this. But I find the above are starting to hamper my hover abilities. I can keep it in the air for a full battery, but only in about an 8ft square. I actually have more problems with elevation then with movement. Only have about a 7ft ceiling to work with. So the heli is either a couple inches off the ground, or 1 little click more on the throttle, and it's on the ceiling. I do a lot of elevation juggling up and down to keep it at a somewhat constant elevation.

Blades have only been replaced once as I got over confident and tried FF through a 3ft doorway.
