Hey, that looks familiar 
One thing you might consider changing is the location of that distribution board. In a severe crash, the arms can be pushed inward, so you have to think about what (if anything) they'll hit. It's far less likely than it used to be when there was only one block per arm, but it could still happen. If that power pcb has copper to the edge of the board, and if one side is + where the other is -, a crash could get more exciting than you may want 
Cheers,

Hey Rusty. I am not going to crash it

yeah right. I did consider the movement of the arms in a crash. The PCB is mounted directly to the bottom frame plate..the arms can slide inwards and clear the PCB by 2-3mm no problem.
BTW, what is shown from the 480 OSD FPV camera besides video? Is there any data available without something like eagletree osd?
No. I will not use an OSD with this machine..yet. Maybe in the future though....OP CC PRO OSD ??
Hey Juz...what's your expected AUW with this new frame? I'm looking into a Rusty frame because the ability to upgrade to a hexa with just some parts is very enticing. Just wondering what the weight is. Also what size booms did you go with?
Yep the booms are trex 500. Not sure on AUW yet. So far its 1300grams. Will tell you soon, when my board turns up and I finish the build.
