I have been flying with turnigy motors or a while - as budget dictated such -  but after flying with a hyperion motor (a friends) and a scorpion - I have realsied just how much noise the turnigies make..

even just  turning the can over- the turnigy makes a lot of noise where the Scorpion and AXI (i have one of those now too) make hardly any at all....

I think I am going to use better quality ones from now on - just to keep things quiet..

Wynn,
What kind of noise are you hearing? Also is there any rough feel to the bearings as you turn the motor? I have a Trunigy that is in my Stuka and it doesn't seem like it will be different from the AXI I have in my profile. Do you hear the noise if the motor is out of the ship. My AXI in the profile does make noise if I spin it while mounted in the ship. The fuse kinda amplifies the normal sound. You might have a bad bearing in the motor that is make the majority of the noise.
