Has anyone managed to get a quad to fly well with DJI Naza, long booms and big engines?

 

[Gunter]

Any reason why your booms are so long? How does it fly?

It does look like a nice neat build though, well done!

APC 12x6

@Gunter - thx, perfect in calm weather.
The reason for the long arms are to test a little.

it almost looks like the props need to be bigger, with stronger motors to power them for the size and all.

Hi,

Just wondering how much flight time you got out of the battery?
Also,how much will this beast lift?

Thanks in advance

Phil.

Sorry for being away too long, as always too many projects going on.

I shortened the booms, but still as wobbly in the wind and descent.
So then I tried with smaller propellers and immediately it flew like a dream.
