Blue smoking MMM

I've only added some heatsink to stock bec wiring.
It is much better due the heatshrink, on stock bec wires I broke many times the bec wire.

It's strange because, because on V3 I had no problem at all!
V3 died only due a crash and missed some smd's components.

Possible problems:
The leaking condensator.
Heatsink, because glue is not transfering sufficient heat.

This the second time I am using the new MMM, after the rip V3 MMM.
O yeah I really don't care about the warranty.
I am honest and wanna share some problems to make the product better hahah:-)
