I just got a P1 from my dad for free. It's basic, has a few extra 2800 MAH batteries, the antigravity motor upgrade, but nothing else. I want to mount a gimbal, preferably a three axis, and install and FPV system with iOSD. I'm beginning to wonder if it is worth putting that money into the P1, knowing that I'll have to upgrade the board, etc. And fight with poor flight times, or if I should just put that money into a P2 instead. Thoughts?
