It';s a nice frame,the subdeck holds the ESC';s and pdb very  tidy.
Mine is built for duration  flight,its relatively slow but nice and stable.
It carries a gopro gimbal very well.
I';ve used emax 3506 650kv  with 11/4.7 carbon props. On 4 cells
Motor too motor is 60cms.

I have a decision to make because if i go for this frame build i would have to sell the S550 hex, this reptile would be more portable and a little larger in the sky, tempting though, i seem to remember reading that it does not have a PDB, not a deal breaker though

It seems that there are a few different six HJ-H4 frames some at 450 some at 600

NOOOOOO!!!

I always get scared when apollo says he';s going to sell his S550  ;)

I think you should keep the 550 and get the HJ-H4 anyway. You could probably double up on spares, too.

As for the PDB - I found it useful on my 550 build, but haven';t missed having one at all with smaller quads. I';ve even looked at stand-alone and custom-built PDBs for future builds.

The frame does look nice on that HJ-H4, though.....  :hmm:

I made my own pdb out of a couple of strips of copper clad circuit board mounted on nylon bolts and washers . (maplin ) The esc were mounted at each corner of the internal box section ,one of my tidyist builds.

And as mentioned above keep the s550,  ~~

Lu-man you really dont want me to sell your S550 virtual sibling, hell they were both born at around same time, i think my one came out of the Naza womb first, cant give the space for 2 large drones

Heheh. Yes, your baby was a little earlier than mine, although I went for the Tarot in the end :)

And space is an issue... I';ve got my 550 under the bed at the moment (much to my wife';s dislike), with my W-607 hex, Ghost quad and Robocat under the stairs, and my STOL 500 and Diamond 1100 in the Summer House....

If I trade my SUV in for a TRansit wan, then I';ll have space for the kids AND a mobile hangar...  :rofl:
