in need of advice...

Nothing really except disable the internal BEC in the MM. You do this by cutting or taking out the red wire in the RX plug from the ESC.

Aside from disabling the internal bec, I usually add a capacitor to the main power leads. I just solder it to the back side of the board where the wires are soldered. A novak power cap usually does the job:

If you really want the MM to stay cool and have a super smooth startup, send it to Griffinru to do his stage 1 mod. He adds extra heatsink material inside the MM and mods the caps, among other things. I tested his modded mm back to back with a stock mm and his stayed much cooler and was much smoother too.

i can't believe how much information is on this site, it's crazy.

i have a couple more questions:

for the bec is there an advantage of the ubec vs. the ccbec if i'm running 4s? i see that the ubec has a max input of 40v, but for a 4s it seems, to me, to be just a preference.

battery holder? i thought of just using gorillamaxx velco straps w/ some kind of padding, but see a bunch of guys build actual housings.

is the stock spur gear ok?

lincpimp you wouldn't happen to have a picture of the capacitor installed? i'm much more of a visual type person.

thanks again

For 4s, a regular UBEC is just fine. They are typically rated for 3A, which is more than enough unless you are using some really high torque/speed servos and/or using multiple servos. However, a good 3A UBEC is about as pricey as the CCBEC, so why not go with the higher capacity one? The high voltage capability is good if you decide to go with a HV setup in the future, but otherwise is not really needed.

Straps work good for battery holders, but some of us are quite hard on our vehicles and want something a little more sturdy. Depending on how the straps are set up, the pack could still slide around. Making your own holders lets you size them exactly as you want, keep them from sliding around, and can provide more protection from stray rocks and such. Plus, it's cooler to have something custom.

i can personally tell you that the gorillamax straps are total crap. they tear if the wind blows too hard.

if you're going the strap route, get heavy duty velcro. i recently found some stretchable velcro staps from horizon hobby and love 'em.
