    C. C.1/8 Sidewinder ESC 1515B - 2200Kv Motor vs. C. C. 1/8 Mamba Monster 2 1515 motor

    How does the new Sidewinder esc & 1515B motor stack up against the older MM2 & 1515 motor? There seems to be a big difference in price.

    90 amp ESC and 11lb limit with the 8th.
    120 amp ESC and tons more programmability with the MM2.
    Whatever it is I just typed... could be wrong.

    thank you, Sir. I think I'll go ahead with my plans for the MM2 & 1515, then

    Probably a good idea. I have read of them working in heavy RC's, but they geared down pretty slow to compensate. I myself would still be worried about burning it all up...

    I've been using the MM2 & 1515 in my summit without any problems. I really like the way in runs, I get tired before it does!!

    I just installed this Sidewinder 8TH system in my Summit... look in the Summit page under my user name to see my progress with it. I plan on doing some testing but right now it is snow covered outside. My concern with it is temp since a Summit is heavy. Same concern as Jimmie. As for it working in a Emaxx 2nd gen you will be at it's rated weight limit but shouldn't be a issue as long as care in gearing is taken and temp monitoring.

    The only difference I have found out between the 1515 and 1515b motor is the can. Sidewinder is smooth and the mm2 motor has machined cooling fins in it. These motors run cool from what I have heard so not sure if the extra cooling fin thing is needed.

    As for the esc the Sidewinder is a continuos 90amp rating and a 120 burst rating and is castle link compatible. I haven't hooked my link up to it yet. Just installed it this morning in my truck

    Don't get sidewinder it can't handle the weight of an eye maxx. I talked with someone from castle and they said that they need to change the description because it can only handle 9 pound vehicles not 11. I learned that the hard way. Burnt up on second run on only 4s lipo.

    So what the heck!!!!!! Are they going to warranty upgrade people that actually bought these for there monster trucks!! They should have marketed them for 4x4 sc and buggies if they can only handle 9lbs.

    What was your gearing and what batteries where you using?

    I thought naming the combo "8th" was a mistake from the get go simply due to the ratings on the ESC.

    Battery shouldnt be a issue with what you had... 90amp should be okay with a 11lb truck. You have stock tires or oversize, running in deep snow. Just looking for clues as to why it blew up so fast on you is all. There has been others I have seen using even lil 550 setups and not burning up? Curious, huh

    From what I have read your gearing "sounds" close also. I have 14/68 setup in my Summit with the 8th. Still gonna test it and see what temps are e t very carefully.

    Like I mentioned before thou. IF my hobby shop had the MM2 I would have bypassed the 8th and went straight for the MM2 hands down!!

    I phoned Castle today to double check the weight rating and recommended gearing for a Gen2 Emaxx running the Sidewinder8TH. Guy guaranteed me that this system is still sold and can handle 11lbs trucks no problem. He recommended 20/68 gearing for a stock sized tire and weight Emaxx. If running bigger tires then drop down the pinion and watch temps.

    One thing to note here is that we all live in different envionments and weather etc... Watching the temps is crucial to safely operate these systems. Gearing by the manufacturer is only a recommended starting point. Also you can help with temp control by running 4s instead of the overly insane 6s, LOL

    Back to the OP... did you order your MM2? and if so how do you like it?

    Does anyone know for sure what's the difference between the 1515 motor and the 1515B? Aside from the can that is. There's a big price gap between the two.

    I have had the 8th combo for 3 months now. I am not as enthusiastic as I was before about the motor.
    The speed controller is adequate . The motor cannot be pushed like the original 1515 . The 1515b gets hot quick when its over geared . I clocked 78 mph on a slash 4x4 with 6s . Those missing 30 amp from the esc rear there ugly head when pushing the limit. If you have never used a MMM you won't notice anything .They really cheaped out on the motor.

    Well its blown .The motor is fine. The esc caught fire and melted it self to my rig. I am sending it in so I can replace it with a 100 amp esc from ..I am sick of sending castle escs back for warranty.

    I have the MM2/1515 in my revo conversion, and my neighbor has the SW8/1515B in his. We run the exact same 4S lipos in each. My revo is about 2-3lbs heavier than his, and they run about the same speed. I was very impressed with his SW8 combo, and for the price, it is pretty good. I think the MM2/1515 has a bit more torque, but it may be his slipper is slightly looser than mine.

    I know this contradicts a couple of posts here, but the SW8 handles the weight of the revo with no problems and his has about 30-40 runs on it so far and it is still going strong. It is a revo 3.3 conversion, so it is heavier than the e-revo too. He also runs it with the original Big Joe tires on it too!

    Mine had the gearing they gave on only 4s and smoked 5 minutes in my first run. My truck ways 9 pounds. I have no idea. But if you can save up for the mm2.

    Really, if you can save up for a MM2, do it. Not worth the risk in my opinion. If you want a cheap brushless system, either do a Traxxas power up or go with another brand in my opinion. Good systems are out there but if ur investing in a brushless system, get one you won't have to worry about. Just my $.02

    Amp ratings on ESCs are useless for comparison purposes across brands since none are measured the same. Don't get caught up in the numbers.
    Alt-248 on the number pad =
