    Has anyone installed a MM2 and 2200kv motor

    I've seen a few of these on youtube and I just did a castle upgrade to my Stampede. MM2 and 2650kv motor. It's awesome and I love it. Has anyone done this to their Summit? If so, how do you like it? what are a few things that I should be aware about?

    I didn't do it, but I have heard that you need to be careful or you will be replacing parts. And the diffs don't like brushless power. And remember you have a 13lbs missile if you go too fast. And the stock tires BALLOON badly under brushless power.

    If you want precise crawling that setup is not ideal.if you just want fast that will do the job quite well

    I have the MMM2(mamba monster 2) and I LOVE IT. It crawls great and has plenty of speed. I have it geared 14/
    68. I would suggest it!

    Yeah, the videos I've seen show the Summit crawling easily.

    I'm running the MM2 with OEM gearing and 3S-power and it is plenty fast for me. You really can't use all the power. I haven't even found top speed yet.

    The Canyons are not suitable for this set-up; IMO - the only reason to do this mod' is for speed; that's why I did it. I'm running some shorter-wall tires and those are a lot better on the street.

    Crawl-wise- it's not bad. I've played with the Castle Link and it cogs a bit, and isn't as controllable as the Titan, but I kept that motor so I can switch when I want. I really just wanted to do wheelies, and bought the MM2 at pretty much the same time as my Summit and didn't know it did wheelies stock, lol. Anyways - MM2 is not for crawling; it works, but isn't as good. maybe a sensored BL would do better.

    I love it. If you have the $$$, you can't go wrong. I finally broke a axle shaft because I was jerking around, but I consider it a fuse, so I don't care. Adjust that slipper though...

    I use the MM2 & the 2200 motor geared at 18/68 on 6s...... lots of power of course. It climbs well and have plenty of speed. Ran thru fairly large puddles and where almost everything is submerged and had no problems. Esc fan and castle blower fan still work after being in the water. I haven't had issues with my diffs or the half shafts but a large and small bearing inside the tranny just failed other wise it awesome ! I just need to rebuild the tranny and I'm going again, hopefully I can find some metal tranny gears if they make em, don't think it need though.
    Slash 4x4 and 10 other Models. Too Much !

    With any system that has this much power the slipper adjustment and throttle management are very important.

    Also, don't get aggressive with throttle while the diffs are locked.
