Quote from: Hands0n on Saturday,September 28, 2013, 15:40:44 I';d have thought that the vibration would have to be particularly severe to cause problems at the IC level. That said, marginal or poor quality soldering of the components to the flight controller circuit board could cause premature failure.In terms of solving the issue I have found through direct experience and much advice from this forum that you should tackle the source of vibration first and then add in one of many various dampening techniques for the FC itself.Propellers are probably the greatest source of vibration - you';ve got to balance them and their hubs as best you possibly can. The difference in vibration generated and sent into the air frame can be enormous. I fell foul of that when bringing an APM 2.5 into service. There is a rather long thread on this forum with my experience and the rather significant results I ended up with.Next up would be the motors themselves - check for bent shafts, they should run true.As to dampening materials, there are several. I ended up using two slices of Moongel cut into four pads mounted on the corner of the APM 2.5 casing. Vibration at the FC itself was measured at well within the Arducopter';s required minimum amount. You don';t want to put too much dampening material or you may cause other issues.Then there is anti-vibration foam in both plain and sticky backed:http://www.ebay.co.uk/itm/Anti-Vibration-Foam-White-Latex-Foam-FPV-Camera-mount-ideal-for-sensitive-item-/111100507982?pt=UK_ToysGames_RadioControlled_JN&hash=item19de1b374eand: http://www.ebay.co.uk/itm/Pack-of-8-Self-adhesive-Anti-Vibration-Grey-Medium-Density-PE-Foam-Pads-/231060159294?pt=UK_Pet_Supplies_Fish&hash=item35cc423b3eJust a few ideas ...

I guess I need to balance ALL props, regardless if they are carbon, wood or plastic?Nick
