I have vibration on both my trex se v2 and copter x se v2. Both are using 401, S9650, HS65MG. There is no vibration when it is hovering. The vibration stops when the blades are at hovering speed. I tried removing the blades and run the motor at full speed and did not vibrate. I'm assuming my blades has something to do with it. I have align 335 pro wood blades. I didn't mind the vibration b4 because the helios are fine when hovering but I put my Trex 450 se v2 in a heliartist 500d fuselage. It vibrates the canopy off. If the vibration is normal, I need information on how to minimize it. Thanks in advance.
