Ok guys i am thinking this is a easy fix i just built the 50n2 i got the gy750 and using the a brand new os 55hz engine still havent break it in . i spool the engine up and i get to 30 percent and see it wobbles then i put throttle down to 0 and wobbles worst. i change main shaft and feathering shaft. i havent changed no setting in the engines yet is the head speed causing it or is there a setting i am missing on the gy750

Sounds like gyro. Try checking over your settings and checking swash gains

engine tuning?
I wonder what head speed you are turning when the wobble appears?
Are your needle settings too rich?

-I'd double check your settings on the gyro first
-Check your engines needle settings.
-What happens when you exceed 30% on the throttle?
-Are the blades strait when you spool up?
-Are your blade grips too tight? not allowing them to straiten?

With a brand new kit & no crashes, It would be hard
to believe that you would need to replace the main
& feathering shafts.

Good luck!
We'd like to hear what turns up.

Went through this **** My self
Nothing wrong with your heli.
Its the 750 setting.
This is what I did after Reading Dr Bens artical.
Go into both ELE & AIL expert settings
I guess the outrage velocity has a stiff head design.
I did this and it fix it.
Lowered my D gain from 200 to 30 or 40. Try 30 first.
Changed my head response fron 1 to 2.
Also the there's a setting in there thats Quick, middle , moderate.
Change that to moderate.
In your radio. On your low head speeds use a low gain in the (60's) in your ele & ail gyro gains. Im using 75 % gain at 2,000 head spead and might need to lower it a tad.
There also a thread in Run Ryder from DR Ben that explains in detail all this. Very good reading. Try to find it.
Try that. It helped me. I can email you the Thread if you want me to. Dont know how to direct you on here to it.

If it's not a challenge. It's not worth doing.
