I just read through this thread again and have some questions.

First, isn't 350 -450mAh per minute kind of high on the current draw? Othello says that he was running on concrete, so if resistance goes up when running on dirt, then you can assume 450mAh consumption. If this is right, then you're only going to get around 18 to 20 minutes of runtime on an 8Ah pack. That isn't very good.

Even my Feigao will get me half an hour. What am I missing.

Another thing is that the rotors in my Feigaos look just like the rotor in the pic that was posted. Again, what am I missing?

What is it that makes these motors better than Feigaos?

I just need to know before I make another purchase that I'm going to regret.
