AP: Quad w Axi 2820/14 or Hex Axi 2814/22?

Which do you think is a more stable platform for my MK controller and Rusty frame?

Quad with the larger Axi 2820/14 (150gr)

or

Hex configuration with Axi 2814/22 (100gr)
similar to this:

Thanks,

I like it simple. Since neither one of those configurations will offer redundancy I will go with the quad. The hex will have more motors, more speed controllers, more props and more things to go wrong. So far I have found the quads to be the most stable multi rotor.

Thanks Seismic, I thought the same thing but I read somewhere that more smaller motors are smoother than several larger ones..... Wonder if anyone has ever done tests?

I think it will really depends on total weight carried. it does get trickier to find a combo for heavier setup in quad. so, if your total weight is less than 2kg, I would stick with quad. at certain weight, there are dearth of propsets available, which makes it tougher to setup larger quads.

Why not a Y-6 or X-8

Coaxial thrust make decelerating very smooth and offers redundancy.

My Y -6 flys much nicer than my quads.

And it does great in wind.

Adidas: I thought about that too! I thought I might build a quad and then transition it to a Quad-x. Might be the best path.

i think a X-8 would be killer..

I think I am going to buy the x468 traveler quad and built it to a X-8 when i can get my hands on it.

Jago also made a nice heavy lift quad here.

zirt: yea, I saw that! He uses those Axi 2820/14 on other builds I've seen too. This Quad vid is famous:

Gaui - Spring In Zurich (3 min 33 sec)


I did find a source in Canada actually.

But they only had 2 in stock, 2 weeks for the other two....

Yeah I ordered 4 and they only had 1. Took a little less than 2 weeks to get four in stock and they just shipped them to me. The shipping will probably take a while.

I think Icare is your best bet on the North American continent.
