I will build a ArduCopter and thinking about buying ArduPilot Mega 2.0 but is out of order now.
Can I use ArduPilot ATmega 2560 1.4 and ArduIMU+ V3 instead of ArduPilot Mega IMU Shield OilPan Rev-H V1.0 ?
No, ardupilot 2560 is designed for the oilpan. The last official word was that APM2 will start production very soon (this week if all goes well). Once the pre-orders are filled and distributors get some stock, regular stock will probably be available by the time you have the copter built.
Ok, thanks for the reply.
I thinks is better to wait for ArduPilot Mega 2.0.
Now I can buy parts for copter and think about how it will be built and read on the subject.
