it's more than just the linkage.the boom supports vibratelike crazy!!It's wierdI just noticedit happening the last fewslights. I'm going tochange the main bearings, I've noticed their a little worn. I have a ton of flights on this bird, I flew herat least once a day, sometimes twice last summer,150+ flights, in the dirtand dust, and desert heatwithout replacing anythingLOL.

Now the weather is good I havent missed more than a day in the last three weeks. I'm also going to changethe main rotordrive gear, and tail rotor belt. featheringshaft bushings, everything............... Another possibility is the Motor, which I think I'llreplace it with thetheAlign, ora scorpion. I probably will get the Scorpion so I'll be able to easily rebuild it., I just put so much use on the motor, I need to babable to rebuild it, out here in Iraq it's dirty, and dusty just plain nasty! I only wish I would have done this earlier, right now is prime flying time, and in two weeks I go home for leave. So I won't be flying until Late July.

Wich Scorpion should I go with? the 1900 and upgrade my ESC to the 100A
