Planeheli,
I have not done much since my initial maiden flight on my hawk because of the weather here. I've yet to even trim the bird out. Because it's not a 3D flyer, i'd actually suspect flight time to be closer to 8 minutes on the 4400 mAh packs, though i've yet to fully test it.
At any rate, it's grounded at the moment because I ripped the ESC out to stick it into a .40 size plane that we recently e-converted. Once the weather gets a bit better i'll be going back to the hawk and setting it up properly. Naturally, i'll videotape the whole thing

.
At the moment, it's rainy and kinda cold, not ideal flying weather

. I can't really do proper trimming in my garage as was shown in the video because it's too small of a space. If you'll notice in the video the helicopter was difficult to hold in a hover because of the constant rotor back draft from hovering in such a small space, not ideal for trimming the model!
As for the prices of the motors, I think much of it is severely overpriced, and I say this as a retailer of many asian imports so it's not like i'm just pulling figures outta my arse.
A good example would be the new Welgard motors we got in recently. Everything about these motors screams good quality design and quality control nearly comparable to AXI motors, yet they're a fraction of the cost of the AXI motors. Not everything that comes out of china is garbage (though much of it IS garbage, so you gotta be careful).
I make it my first priority when dealing with overseas manufacturers to make sure everything is of acceptable quality (and consistency, more importantly) among their product line. If something does not meet my own expectations in regards to it's relative price point, I discontinue carrying it, simple as that. I won't sell garbage to my customers.
Oh, and yes, the hawk pro is a noisy beeotch. Theres like 3 gears in the main drive assembly, plus the tail is gear (not belt) drive. All that gear lashing makes a good deal of noise. I kind of like it though, makes it sound mean..
