Hi,

I am little new to Drone

I have two droneS
1. CC3D OLD board and it is working perfectly

Recently I make a new drone using CC3D EVO
It is working but it isn't smooth to fly and get some vibration

Spec
RS2306 E Max  2750KV 3 - 4S  Racing Brushless Motor
FEW220 Honeycomb PK QAV220 FPV Mini 4 Axis Quadcopter Frame
Hobbywing SkyWalker 30A ESC - RC King
Carbon Fiber Propeller 5 inch Prop

Both drones are using same spec except FC

Please advice

The clearest way to narrow down problem would be to swap boards.  Then ask: Does problem follow board or follow aircraft?

Vibration is usually caused by props out of balance or bent motor shafts.  Too much vibration does cause the main sensors (gyros and accels) to read incorrectly, causing bad flight.  To start with you should balance your props well.
