Conventional Hex or Y6?
 
OK, I'm looking at a new copter using a Naza and GPS, primarily with the intention of carrying a Panasonic compact camera. I was originally planning to go with the DJI Flamewheel hex frame, but it struck me, from reading on this forum, that a single ESC or motor failure on a conventional Hex type is very likely to lead to a crash. I'm wondering if using the same equipment, but in a Y6 type is less likely to crash in case of a similar failure. So, I suppose the real question here is, will a Y6 still be flyable with one motor not running?

They both are still flyable assuming your 5 remaining motors can handle the weight used to be controlled by 6. Y6 are a lot more controllable if your weight is ok when their is a failure though.

Hex.
Y6 did not give sufficient flight time when loaded down and I am at high altitude here in El Paso.

OK, thanks for your opinions chaps. I can see that the lower props on a Y6 will always be working in the downwash of the upper props and that this could lead to vibes etc., but I can also see that the Y6 is going to be more controllable if a motor should stop in flight. I guess it's all down to a series of compromises, as always!

Some are getting good results with the Y6, and say its smoother in flight. I think you will have vibration issues with any multi, just need to make sure you have good isolation to the Gimbal.

You wont see anymore vibes because of the coax design of a Y6. You will however find they are a bit less efficient. The trade off is they are MUCH smoother in the wind and for that reason I will be moving from a flat hex to a Y6 on my main machine.

I've ordered a Y6 frame and will give it a try. I can just swap everything over to a hex if I don't like it for any reason.

Yeah frames are cheap it's the motors, ESCs and flight controllers that cost money.
