A friend is also going to join the journey, and we are going to build 1 quadcopter each. The chassis we have bought is the ST360. It is 360mm diameter and comes with 4 motors and props. Basic specs:
- * chassis diam: 360mm
* chassis weight: 170g
* motors: 4 of ST2210
* motor weight: 80g each
* motor speed: 1050 rpm per volt
* motor max current: 10.2A
* motor thrust: 600g each
* battery: 3 cell Lipo (11.1V), 2200mAh, 25C discharge (that means it can supply 25*2.2A=55 amps!)
* battery weight: 190g
* electronic speed controllers (ESC): 15A with 5V BEC
It is designed so that the maximum thrust of each motor can on its own lift the entire craft.
For the electronics we plan to use:
- * pyboard for control logic (of course!)
* MPU9150 for gyro (I don't think the accelerometer will alone be enough to control it)
* BMP085 digital barometer for determining altitude
* maybe a GPS unit for tracking and automated "go to" commands
* NRF24L01 for wireless control, connected to another pyboard on the ground
