| You need to put a bright colored piece of tape on the tip of one blade and spool it back up. Check the tracking right when it starts to get light on the skids, not when they are spooling down and almost stopped. This will allow you to determine which blade is high and which one is low. Once you know that, you can adjust the linkage a turn at a time until they "track" through the same path. The linkage you need to adjust is the long one, approx 100 mm, that connects form the swashplate to the top of the head. It's the longest one on the head assembly. It may take some time to see a change so you might want to start with 2 turns then back to 1 turn when its close.
If you want to have a bit more top end pitch, adjust the low blade up to match the high one. If you want a little less top end pitch adjust the high blade down. If you want to leave your pitch semi unchanged, turn the top blade down and the low one up at equal turns. Hope I didn't confuse you with this last part.
