Dear all bit of advice please. I building my first Chaos 600E, and would like every ones opinion on we're the best spot to mount the SBEC? The only thing were I have it is lack of air flow? And the BEC just reaches the Rx mounting at the back. Any ideas? Attachments:

i have mine mounted on the outside of the frame on the right side just in front of the main gear, esc is mounted directly across on the left side...

I mounted mine on the inside. I had to be different! Its protected in case of an event. I used double sided sticky foam like whats used on gyro's to mount it along with a spare velcro strap that came with the kit. I then glued the on/off switch to the inside of the frame just above the ESC. I also made up extension wires for the battery to make things neat and simple. Attachments:

valkman, Looks sweet...I really like the switch placement! The only thing i would look at and pay attention to is the motor leads rubbing on the carbon....That carbon can be sharp and cause a short there...
MAybe the soft side of a piece of velco stuck to the frame would be a good fix... Just as long as your aware..

The ESC and BEC should be mounted on the outside of the frame so they get air to cool off.The cooler your electronics are,the longer they last..Last thing you want is it over heating,good chance of fire...

Thanks for you comments There is slack on the wires and they are not rubbing against any corners and I have also sanded the edges smooth anyway. The motor wires are on the left side ( see pic ) and fit snuggly and neatly between the side frame and ESC. I have 4 flights on her now and the ESC only gets warm but Im not a stick banger so if you are one ( like onthedeck !!) maybe putting it on the side of the frame for better cooling may be for you.

Ive seen alot of fires at funfly's because people stick ESC's and BEC's inside the frame's..They also run hotter for people that aren't 3D pilot's so that's backward's.A 3D pilot is alway' moving around so everything get's alot of air to keep thing's cool,even if it's in the frame's..For someone that's at most doing sport flying,electronic's run hotter because your not moving around as much.If you read up on some of the ESC's/BEC's,it's stated in the fine print to run them in the open or risk fire..Lock-out's/loss of power happens sometime's because the BEC get's hot and stop's working.. Also, If you have a Castle esc with data logging,do a 3-4min hover with a little forward flight and save the log.. Then do a 3-4 min flight moving around fast with flip's roll's ect.. and save the log..
You'll see the faster you move around,the cooler thing's are..ESC's and BEC's need to be in the open no matter what kind of flying you do.It keep's the risk of fires and lock-out's down. Just putting this info out here....

As I said, mine only gets luke warm. I did read the instructions for the ESC and it states "Make sure there is sufficient cooling for the controller by ducting air through cooling holes from outside airflow. Failure to do this could cause controller shutdown or damage."
Clearly this is for planes or scale heli. Bottom line.....if it was getting hot....I'd move it, but it aint so I wont! I dont need a log to tell me this.

It's your stuff so no arguement from me,I was putting the info out for the OP and other's ..The outside doesn't really matter because the inside is much hotter.That mean's if the outside is warm,the inside is hotter.

Scale fuses have vent's in the top and air is pushed through the vent's by the main blade's..

Ahhh, gottcha bro.! Thanks.....
I was just wondering as I know at some point a scale fuse will be on my list of stuff to do...LOL.
