E-Revo set up?
 

Hey everyone, I'm new to electric...I've been running a Slash with MM 7700 with many fun times and great racing results. I want to send my son, who is stationed in England a new E-Revo and was wandering if I could send it off with my MM7700 with a new Hyperion E-Revo 6000mah 7.4 combo. I can pick up a lees powerful system for my slash. I would add a fan to the esc and a heat sink to the motor. Would this system be reliable and powerful enough to satisfy a semi experienced basher/racer. Or do I need to go moor extreme on the motor and esc. Or do I need 2 lower KV motors and a different wiring set up. Any help or advice would be appreciated. He has amny lonely hours to burn and an indoor track near the airbase.

MM would be ok with the E-Revo but you need a different motor maybe the medusa 36-60 can or Feigao motors and if you can afford it maybe Neu motors. For 4S 2000-2200KV would be ok but not ideal just my opinion. Try the Revo forum a lot of guys posted their setup. Ohh and the 7700kv motor might just puff if you put it on the E-Revo.

Hope this helps

Thanks for the info, I was afraid of that answer. I think I'll send it out stock with the the lipo combo for good runtimes and a little more speed than stock. When the MMM comes on line maybe I'll send him an X-mas present.

he will want/need an LVC for the lipos. Stock EVX2 doesnt have one

Thanx, I already have two of those standing by.

It would be cheaper with 2 MM 7700's
 

Is it possible/feasable/smart to just slap in the MM/7700 and just spend $180 more to slap in a second one with a y harness, running 2 8000mah 7.4's. This would slice the load in half, stay with in the weight of the original truck since it has 2 industrial motors and is set up to run heavy sub-c cells. I realalize that this would not increase the speed over what one brushless unit would do but it should be reliable, right? Would this unit need a bec eliminator set up, I would think not. Th:rofl:anks again for the help!

You would be much better off getting the BEC and using the existing Mamba Max and using the lipos as 4s 8000, and getting 1 larger motor, say a 9xl for $70ish. 2 Castle motors dont work well or for very long in a monster truck, they are just too small and too high of a KV., if you want reliable, dual setups arent the way to go. I ran a v-twin for 6 months and its alot of tinkering, hit and miss and close watching temps...Sell the CC motor on ebay for $50 ish , buy a CC bec and ?Xl motor only $40 out of pocket. My opinion

+1 to JayJay

not to mention that your setup will be heavier
some cons for dual
* complicated setup
* need unslow for proper battery discharge
* motor must be in sync to prevent stripping spur or killing the other motor/esc
* more parts prone to more parts that might break

single motor setup will be more reliable, expensive at first but cheaper in the long run. IMO

OK, let me get this straight, lose the 7700, keep the MM, add a fan and a BEC eliminator from CC. Get a 9xl(is that a fuego motor? and does it use standard pinions?) Look up a wiring diagram for 4s. Will the newer traxxas connector hold up or should I switch to deans?Any suggestions on a receiver batt. box.

yup you got it. from what I've heard traxxas connectors pretty much stand up to deans so no need to replace that. You dont need that receiver batt box nor the rx batts, this is replaced by the CC BEC's job :)

Don't forget pinions. go with a 16, 17, and 18. Anything higher than that might make the esc thermal, it did in mine anyway. (erevo, mm, 8xl, 4s lipos)

Thank alot guys the help was appeciated.
