What batteries are these your planning on running that are 4s and fit in the battery box on the E-REVO? 3s 4900mah is a tight squeeze.

I couldnt tell you anything about those servo's. Personally, I'd stick with the stock traxxas ones until you can afford to buy a single good one.

Also, If you are buying 4S batteries, you can ONLY run them in parrallel on the MMM - its only rated for 6S.
i hope the radio will release before otherwise i could try those glitch busters
i was thinking about staying stock but they cant be much worse than traxxas servos. better torque and speed. i want to save for a good single but i the 5955tg's are discontinued and replaced by the more expensive 7955tg and would need a programmer i think and an aluminum single arm. and as stated before im runnin them in parellel

Yeah, so why spend the money on these...at 19 bucks each, I can almost guarantee that they are not going to last, and highly doubt you will gain anything over the stockers. The single biggest issue people have with the stock ones is that they can get out of time, and work against each other. IHMO, you will only waste 30% of the money you could use for a single servo.
You dont have to purchase anything more than the servo to run it. You can just trim the unused arm off (or just leave it). You dont need the programming kit either - thats for flyers.

I'd listen to the other guys on the batteries....I think you might have a hard time fitting 4S in the tray. My brother in law has the 4S 4900 Zippy's, and if I get the chance, I'll see if they fit in the tray on the chassis I have.

if the servos dont work then oh well. back to stock. if they do then people have cheap replacements. and the batts are 140x30x49 so they fit fine. if they lied oh well. i can sell them or mod the trays

If you want cheap chargers with a built in balance harness, then visit hobbycity- I would advise against $30 weird chargers that magically auto-detect the the capacity- thats too cheap to be a safe bet in my eyes.

I would say take your pick from the ones on these pages:

http://www.hobbycity.com/hobbycity/s...6&ParentCat=85

Most will require a seperate power supply though- the hyperion 50watt jobby has a built in powersupply and balancing feature for a modest $130-150, though charge current is reduced when you use larger voltage/mah packs.

Interesting charger that- chargers through the balance taps. That does limit you to a 2amp output, but combined with that power supply it will make a nice cheap setup- it will work for charging 4s lipos yeah, have a read of the reviews- some useful info in there

No. You are effectively wiring the batteries in series. As earlier stated, MMM is only rated for 6s. ∂

Yes that is wired in parallel, what ESC is that w/ dual plugs though? The jumper on one side completes the circuit and the batteries are in parallel into the other plug.

Put a male end on the MMM then use http://www.maxamps.com/Deans-Series-Adapter.htm this for a series connection and http://www.maxamps.com/Deans-Parallel-Adapter.htm this for a parrallel connection. Of course you can make your own with whatever connector you want. I prefer Traxxas connectors myself, MaxAmps only sells a series connector with Traxxas ends, but you can make your own parrallel one.
