I have a spare set of main blades I could put on but I have a little concern about that tail boom rotating in the mount. I could drill and put a screw in to keep it in place but I think at this point I just need to send it in.

What can a person do to try to correct a dynamic inballence in the head? Tonight I took the main blades off and looked at the head while it was rotating and did see a wobble in the head assembly. I'm talking like .02 out here so it isn't much. I took the head assy off of the main shaft to verify that it wasn't bent and spun up the motor. It turned nice and true all the way up to full speed. It appears that it is the plastic pieces above the main shaft that is not spinning true.

I got out my digital calipers and double checked all the linkages and they are in spec with the manual. I also checked the lenght from the inner collar to the beginning of each of the two flybar pattles. They are within .005 of each other. I would think that this would be good enough.

If anyone has further info on this for us that we can use for future reference when trying to troubleshoot issues like this I would greatly appreciate the posts with detals about what to look for and how to correct.

Thanks from this noob
