After this potential problem was pointed out in this forum, that's what i did. However, some of the posts were so close to the heatsink that I had difficulty to insert the shrink. In addition, the shrink also interfered with the case. Had a difficult time putting back the case.

I'll try to put up a pic later for more clarity.

Do you think Novak Glitch Buster Capacitor will reduce possibility of failure?

It is supposed to "store power from the Battery Eliminator Circuitry (BEC) and act as a filter to eliminate noises generated by servos" and "reduce load on BEC".

Do you know parameters of that capacitor?

Depends on what is causing the failure. If it's simply amperage load, then no, it won't help. If it has something to do with filtering, then maybe. If the issue is with a bad BEC component, then no.

A cap inherently stores a charge and filters out AC. So, it provides a "reservior" of sorts that will help with current draw when servos need more peak currents. However, if the load requires a constant high current, a cap won't help much at all. It also helps get rid of noise that may be present on the BEC output. However, if the noise is getting in elsewhere (antenna, throttle/steering signal line, etc), it will not help.

Don't know the parameters of that cap, but $13 plus whatever the shipping costs are is a bit overpriced IMO. Just go to RadioShack and pick up a 1000uF (or higher) 10v (or higher) capacitor and solder a servo lead to it.

Here is another option. Marketed for a different reason, but essentially the same thing. A capacitor on a rx plug. less than $5 too.

I have just bought 6,3V 1000uF cap. Unfortunately not SLR.

I hope that simple (13 cents value) mod will lower possibilty of failure. Keep your fingers crossed tomorrow :)

Base of heat sink in my MMM V2 is touching battery connectors :/ I hope little silicone will prewent short-circuit.

I hope I am in happy 50% of MMM owners ;) It works, with some mods, after at least an hour racing. Peak power with Medusa 60-1600 on 6S A123 was 1807W :)
