We have done several Discovery channel shows using a gopro. I would say a high percentage of those types of shows use a small amount of footage from them. The key is to have a decent AC to fly it...... With the H3-3D the results should be better however the wind will always be an issue with the small size of the P2.
I think it's best to have a gopro flyer and a bigger AC flyer like the S1000.
Last week week I was flying the P2 down a hallway inside a hotel, the P2 was great.
Yesterday i I was flying vineyards for a project and I used the big heli and the P2.
