Severe shaking

Hi all. My Eco 7 Ranger is experiencing severe wobbling/shaking as I increase rotor speed. I'm afraid to take it to take off speed as it seems it's going to come apart. Main shaft is new, carbon blades are balanced, spindle is new, flybar is straight but I wonder if blade tracking is the culprit. I've been messing with the adjustment screws Does anyone know what's the proper pitch's angle adjustment for the E-7? I do not find them in the manual Thanks.

`Hi there!
I have/had the same problems it is still your blade tracking and the stifness of your balde holders when you have it to loose it will shake.
Also when its to fest it will shake find the best grip.
your blades are maybe tracked out (to much pitch) so screw them all the way down and start over with tracking.
Mostly the shacking will occur with these components.
Make also sure you have the main gear and shaft to not alow to be loose in your frame.
Maybe your cross shaft is bend?
Hope it will help you!

Hi, Make sure you haven't fitted the main blade grips the wrong way around so the pitch deceases as you increase the throttle. Also check the blade holder shaft is not bent. I had to same problem with severe wobble when spooling up and it was because I had to main grips up side down. if you pull the fly bar up the main blades should increase in pitch. Also make sure the main blade bolts are not lose. make sure they are fairly tight.

I also had bad wobble from using 2 main carbon blades that were not a matched pair. After 2 crashes I had 1 good carbon blade from each crash but they were not the same weight.
