I had a chance to weigh my rig and I'm coming in at 1.47kg. I calculated my thrust and I've got 3.48kg of thrust which maxes me out at around 1.74kg while maintaining a 2:1 thrust:weight ratio. That's good news to me because I can double my battery weight and still be within reason. Of course I've heard 3:1 is ideal.

Wow!! Good to hear form you, it shows the weight of your rig is perfect for the thrust. Recently I am searching for much lighter frame to achieve more flight time and your rig proves it is possible, Can you share PID settings of your APM too !!

I'm still working on the PIDs, but I'll share them once I've got them where I like them.
