Status: offline 		I flew this afternoon and lost one screw from the seesaw. I was only 10ft off the ground at that point so I was lucky and was able to bring her down softly.

I took some screws fom my donor heli and thread locked them. Make sure you check those, you can't see them directly.

Status: offline 		The experience of loosing a screw helped the tracking issue. Since they are a bit hidden I missed them. I have a new screw in there, thread locked and tightened both, it tracks right on target.

Status: offline 		TEX,
Great to hear about you finding the tracking issue I had one problem similar but turned out it was an out of spec (bad machining) bearing seat/stop in an aftermaket CNC main blade grip. When the darn head was stationary...I never found it loose. When it was rotating, the centri-forces on the grips would deform the bearing stop just enought to drop it about the 1/4 mark. The material that was supposed to retain and center the bearing was drilled out to large. Drove me nuts for weeks....could have lost a blade as weak as it was. This was ofcoarse the old "Sport 500" .45 nitro heli I used to have

Status: offline 		How did you like the nitro compared to the 450?

My friend and I are arguing the fact that I should have gone to nitro instead, but I like the ease of electrics.

Take the 240 out of the equation and connect the rudder servo directly to the Rx. Make sure you center the servo horn. If if it still has little throw, check your EPA settings on the Tx. You should start at 100% EPA.

If the rudder servo works normally then it is possible the gyro is damaged.

Check the pitch slide on the shaft, it should move smoothly with the link off. If not try a drop of oil.

What radio are you using?
