Check vibrations with your Phone

This is my way for checking my quadrocopter for unwanted vibrations, I use my iPhone and it works very very good :)
Everyone that is into quads have a never ending fight against vibrations, and there will ALWAYS be some vibrations so how can we minimize them ?.  

My way use some good motors they don´t need to be expensive but they use good bearings and good build quality. I use Sunnysky motors and they works really great on my quad.

The app i use is called iSeismometer and it works really great on iphone, you can get it for free on almost every phones out there, and it´s FREE :)
So just watch my litte movie :)

Where to buy and find free stuff :)

• iSeismometer on appstore or android marked
• Green magic gel pad you find here  Buy green pad (best for gopro)
• sunnysky motors from epbuddy.com (cheap and great)
