Vibration motor
Vibration motor
If your doing the haptic feedback and are having trouble finding a virbration motor then heres a quick and dirty version
Its nothing more complex than a motor from an HXT900 servo that had had its day. Adavantage of this motor is the pinion on the end is brass so its easy to solder a big blob of solder to it. Not shown in this photo but I have placed the motor inside a tube (donated from a childs play house, its ok my kids have grown up and I was using the tube as a paint stirrer anyway) that has one end capped off and the motor hot glued inside. This tube is purely for the fact that its a big blob of solder and I dont really fancy it flying off and shorting something out when I'm flying.
