Here is an interesting quad frame that Hobbyking is selling. I can see this really working.
Nice enclosures for the motors
A lot of space inside to mount a controller and PDB
and what is awesome is the camera mounting area.
The only problem I see with this is, that it is fiberglass and that when you crash (and you will) there is no replacement parts, so this is for a intermediate flyer.

i had a look at this. no spare parts on HK, it looks like it would break very easy
One day Hobby King will make a frame that has been designed by someone that knows Multi-Rotors.
Physics and aerodynamics would be a start. Nightmare of a thing...
Hi Morli,
Yes that frame looks like it is designed to go horizontally
But the way quad copters go horizontally is to tilt in the direction of motion and then supply thrust straight down in relation to their frame, so even when they are going forward they are acting just like they are hovering.
All thrust is pretty much straight down in relation to the body of the copter at all times and its angle relative to the ground determines it's motion across the ground.
Now if the props tilted, then it would be a different story.
It really is a beautiful airframe, but the flat arms are a not insignificant problem.
I looked at it and the first thing I noticed was the large flat plate area of the arms relative to the prop wash.
If the props were under the arms it wouldn't be a big deal, but on top those arms are going to cause at least a ten to 15 percent loss in efficiency (from back wash and turbulence in addition to flat plate area).
As well as increasing noise and vibration.
I am afraid they made it to look pretty and be easy to mold rather than for optimum performance.
I will be very interested to see others experiences with this, it may not be as bad as I think and I like the camera dome design if it can be made to work properly.
You'd certainly have the coolest looking quad out there.
Beautifull design!
I'd be willing to volunteer to be the test rat, but just blown all my cash on a flying/training vehicle from quadframe :-(
The should have made it water sealed.
Notice what exactly? vibration level or shorter flying time (because of more drag)?
I do not think you will even notice it, its so small of a difference.
I totally agree with Euan.
The arm profile should be vertical for airflow and not horizontal as it is. Sure will have vibration. And less lift and more drag will be involved.
