thanks! sorry for the crap quality. it is a HD video cam but it was dark out. i figured out that this crap turnigy superbrain 40A keeps overheating and shutting down on me. Tried using the governor mode but Im not sure how that's supposed to work.

its supposed to be raining all weekend ..

I think im going to have to install the windows on my fuse and see how it does in the rain

If I could just figure out how to get this ESC right. It keeps shutting down on me and im no where near 40A.

My Turnigy Superbrain 40A does the same. I now installed an extra UBEC so my receiver will always get power.
The Turnigy Superbrain already shuts down at 50 degrees. And my current is only 17 A.
It was very bouncy in governor mode, so I switched that off.

I wonder if it has a current limiting option that can be disabled or turned down? I know the Phoenix ESC have a cutoff that works similar to this, but it can be adjusted for when you're flying a helicopter.

It does maybe you guys can help me make sense of the instructions...

Spec.
Constant Current: 40A **** <- LIES!!!!
Burst Current: 50A *** yea right
Battery: 2-3S Lipoly
BEC: 5V/2A Linear

Here's the manual. Its pretty short and fairly well writtend. Settings details at end.
http://www.hobbyking.com/hobbyking/s...40A_online.pdf

Current Limiting
NOTE: Default setting is recommended. If you change the setting, damage to the controller as a result of over
current will be not covered by the manufacturer’s warranty.
Brake Type
Option 1: Very Sensitivity
Low over-current threshold, will rapidly shut-down.
Option 2:Standard(default)
Moderate over-current threshold, will shut down after a slight delay.
Recommended for inrunner motors.
Option 3:Insensitivity
High over-current threshold, will shut down after a slight delay.
Recommended for outrunner motors. Only experienced modelers
should use this programming feature
Option 4: disabled
Current limiting detection disabled. Only experienced modelers
should use this programming feature.

You need to change it to insensitive or to disabled, which is what they recommend for choppers on the Phoenix ESC as well.

Do you have the USB link for it or a programming card? The standard programming card won't work with it, you have to have the one for the superbrain.

You can, but it easier to do it with a card. I've never flown the superbrain, I've always flown the plush models. Had pretty good luck with them.

As Magic posted, if the problem is RX Brownout, then the problem with that 40A/2A ESC may not be with the 40A ESC portion, but the 2A BEC portion.

I think for the 450, many recommend 3A or higher BEC, depending on how fast the Servo's are.

Here are some cheap HK 40A/3+A ESC's:
(I haven't tried any, since I haven't put the kit together yet)
