| Hi,
you must adjust the mixing arm/swashplate pushrod. Those are the long pushrods connected from the subrotor stabilizer mixing arm to the outer race of the swashplate. You must find wich blade is flying higher then decrease de pushrod length of the higher blade and increase the length of the lower blade. Those pushrods are directly affecting the tilt of the subrotor stabilizer. Are you using 2-6dots grips, 2-4dots grips or 1-4dot and 1-6 dot? Normally, if you use 2-6dots or 2-4dots, both pushrods should be the same length. Note that re-tracking the blades usually requires 2 complete turns of the pushrod ball-links for a on degree change in blade pitch. If you try this operation and your heli is shacking even more, you did increase the pushrod on the wrong side. Try the other one. Remember that if you decrease one pushrod length, you must increase the opposite one by the same amount to keep the linkages from bindings. You can use a 1-4dots and a 1-6 dots grips to have 5 degree. This is what i use. Just adjust the pushrods to track the blades. Also, flying at high altitude need more pitch and flying at lower altitude need less pitch. The less pitch you have, the rotor speed will be higher, the heli will be more stable too. Hope this is clear and will help you.
