Why is it doing this

Hi all
This is a problem I never had in my old F550 system.with 10.5 '' Graupners. I up graded to the E300 and not sure if it's something in the Naza or motors or esc.s.
or what I think it might be the props that come with the E300. I can take off very nicely right into hover. .If I do a 360deg spin where ever it stops it takes off to the right
If I do a 180 it keeps going in the direction it was headed tail first for a good 20 feet of more. I tried lots of gain settings but made no difference . One big change is the power
it seems to have lost . If I punched it with the Graupners it shot straight up to 200 feet in no time, with new props it's very sluggish. The only gain with the E300 props I have noticed is better flight time and coming down you don't get into your prop wash so you come down much smoother .I never liked the feel of the 300 props just not stiff enough for me.
Going from 30A to 15A esc don't know if it makes a change. Everything is well balanced...just seem"s too much flex to respond quickly . Well I will find out . Just ordered some Graupners . Anyone else experience this? It might be caused by something else altogether.... Thanks
William

if you take all the props off, switch to manual mode, fire it up and rev the throttle, do you feel any vibrations in the arms? vary speeds and look for anything

I did what you said and sure enough one motor was screaming .Sound like a bearing....all the other's were quite as a mouse
Going to replace that motor

good idea.... sometimes it happens out of the box, any time you break a prop, etc.
