When toggling to Flight Mode 1, I see the following in Mission Planner in the Flight Modes screen:
- Flight Mode 1 (set to Position Hold) for PWM 0 to 1230
- Curr PWM = 1169
- Flight Mode 1 is highlighted as green as it should when changing modes

Sometime, weigh your quad frame (everything not electronic). It will probably weigh more than 500 grams. And, if you crash it hard, it will break ... into expensive pieces.
Wouldn't it be n

For those that like a simple build, maybe. But for those hoping to make large frames really stiff, then there are better ways. In this issue, we explore the use of laminates using low cost and easy to acc

1 hour 20 minutes - APM 2.5 takes the world record for Multi-Copter Duration of Flight powered by a rechargeable battery. [note: records also exist for hover that can occur indoors and take advantage of ground affect]

Somewhere I remember something about that we use a modified Arduino. So what is the proper response every time I open Arduino and get:

The goal of this build has various missions:
1) show how easy it is to build a ship on par with commercial ships.
2) stay aloft for over 30 minutes carrying a full-size camera.
3) use low Kv motors and low voltage to create an effic
