"Hi Felipe,
I also had this problem, about 3 weeks ago. My battery gave out during RTL while the Y6 was still about 20m off the ground. It came down hard and snapped all 3 legs. They all snapped at exactly the same place your leg did. Like Craig, I…"

"Glad it helped.
Better error messages from that application would be very helpful indeed. Thanks for contacting them.
Nick"

"Good question. I'm more the DIY type, and I'm still trying to DIM, as we all are on this thread. But for someone who has bought an RTF Y6 for somewhere between $1k and $2k, going from ~13min to over 20 significantly increases the value of the…"

"DG, I've not tried with the + plates that came with the motors, but it looks like it would be an improvement. Thanks for sharing this, I will give this a try when I'm able to fly next."

"I was thinking conduction rather than convection as well. A metal plate with just a touch of heat sink compound would probably pull a lot of heat into the metal arms.
The frame of this thing is like a giant heat sink separated from an overheating…"

"That's funny, I would say the only thing missing from Drift mode is altitude control, so I'm looking very forward to PosHold as is. :)
I'm on APM, so I appreciate the concern for supporting the older hardware, for a while at least. At the same time,…"

"I'm interested in some plates as well! I'd prefer the 6-sided Y6B mounting plates to the circular ones, but either one works, I suppose."

"Makes sense. The base of the top motors is probably cooler because it's in the prop downwash, but the motor plate between the arm and the bottom motor may be preventing the wind from reaching the base of the bottom motors.
What materials have a…"

"3D was the problem, but it wasn't as simple as enabling 3D support in VirtualBox. Here's what I had to do:

boot Win7 VM into Safe Mode
insert Guest Additions disc from VirtualBox Devices menu
install Guest Additions and Basic 3D support
as opposed…"

"It is my curse in life to figure everything out immediately after asking for help. There are worse curses, I suppose.
After many hours of internet searches and trial and error, I've just come across this, which says one needs to enable 3D support in…"

"With APC 12x4.5 MRP on top and 10x5.5 MR on bottom, the motor casing on the bottom is no longer any hotter than the top after a 5-minute flight.
The base of the motor, where the two screws hold it to the arm, is still quite hot to the touch, but…"

"Interesting. I assume the 10" APC are 4.7 SFP. What pitch and type are the tri blades? Do you have a link?"

"Interesting - the data sheet (presumably from jDrones) says use a 9x6 on the 880Kv if you're using 4S batteries, whereas 3DR recommends 12x4.7 or 11x4.7. 
The data sheet also says:
Our motors providing best performance with the recommended propeller…"
