Ok Krusader.

Let's see if I will can help you.
I had same problem with my CX when added a heat sinker. I notice 02 problems:
1) upper blades out of tracking
2) landing skids out of alignment - dont touch the ground at same time

to solve...

1) put your heli on a flat surface, running motor slowly and see at level ground if the upper blades are on tracking
02 tips images...no good 01 tip image...all rigth
If no good: adjust the linkage between the stabilizer flybar and the upper rotor blade. See the manual and check again.

2) Adjust the position of skids; they should be touch the ground at same time

good luck
