Just an observation i seen about the MMM

[BrianG]

This is how I see the MMM situation:

V1's had a problem with the BEC. Some flamed, but relatively few. Mods that remove the BEC (when done correctly) seems to keep working fine. Some ESCs have even been brought back from the dead by the BEC mod.

V2's may still had a BEC problem, but the bigger problem IMO is the proximity of the bullet connectors and the heatsink, over time and vibration, any protective layer between the two wears out and possibly shorts.
