Are you following the 'copter just by watching it from the ground, or were you doing fpv or gps routing? Seems like it was a pretty long flight to be able to see it that far from the ground, I would've been pretty nervous even without the failure!

If any of you are interested, I have a brand new Tarot FY680 Pro airframe that I am going to sell. I wanted to give you guys on this thread the first opportunity before posting it on the classifieds. I bought it, unpacked it, loosely assembled the parts by hand and put it up on the shelf without ever building it. I've seen these as low as $180 online so I am asking $150 shipped within CONUS. PM me if you are interested. Thanks.

Would there be any benefit or detriment to mounting the motors upside down and running the props in a pusher prop configuration on this frame?

OK. Why?

The benefits - and I'm speaking here of multirotors in general - are many, of mounting the motors and props on top:-

1. More ground clearance. Also means shorter landing gear and therefore lighter.
2. Easier access to motors and props.
3. Slightly higher centre of thrust and lift on each arm, which improves stability.
4. Cooling airflow over motors (and ESCs if they are mounted outboard).
5. Better safety if any wires or other accessories mounted on arms come loose (won't be chopped by props).
6. Looks better

Can't think of any benefit at all of mounting them underneath. But let us know how you go if you choose to go that way.

Probably not going to try it. I just wanted someone to talk me out of it.

I had to put this build on hold for a year but I finally ordered the rest of the parts I needed (motors and props) and I'm going to start putting it together soon. I still need to order some batteries. I was thinking to get a pair of 4S 5000 packs that I could optionally run in parallel if I wanted longer flight times.

Tarot FY680 hex

That works very well. My build mirrors a friend's 690, which has one 5000mAh toward the rear of the gimbal rails to balance the gimbal, the second goes on top, at the centre of gravity. The 690 has a top battery plate, the 680 doesn't, so I'll be mounting my second battery underneath the centre, on the rail.

His flight times are about 9-10mins with one battery, 15-16 with two.

The benefit to mounting the props under the arms is that the air flow does not hit the arm and cause turbulence.

I don't get that logic.
Wouldn't the "sucked in air" be hitting the arm causing turbulences, too?

My guess is the effect would be barely calculable. Would be interested to see your rig if that's how you've done it.

I almost have everything to complete my build now.

I ordered one of the battery hangers for it since I will be using an AVDome on top.

I have 6mm bullet connectors but wanted to ask what everyone is using for battery connectors.

Also, most power distribution boards aren't rated for the full capacity of 6 30A ESCs. (180 amps). which is better, a wire harness, or a power distribution board, and if the board is better, what are you using?

Ii have motors, batteries, escs, wire, Fixhawk, etc. I am just waiting to figure out how to wire it.

Anybody using this Multistar Elite 3508 - 268kv motor (8S + 13" x 3.8) on his FY680 ?

Until yesterday I was going for the 4108-380KV Turnigy Multistar 22 (6S + 13" x 5.5).

But now, I am thinking that maybe the 8S motor could be the better option?

I hope anybody is using this setup or can tell me if this is a good choice to go from 6S 4108 - 380kv to 8S 3508 - 268kv....

Thanks
