    What’s the biggest motor I can fit in my summit?

    As the title says.

    I recently sent a motor mount to a gentleman who was fitting a massive Snap On motor into his truck. Definitely wouldn't fit onto the stock mount without some modification. These pictures are of his truck. He's got a great rig and did a good job of wiring it in. I haven't heard anything back from him about how it has been performing. I don't know if he's on these forums or not.

    Why can't other people share my opinions?

    Anything larger than a 1515 brushless motor can gut the Summit, as can the 1515 if you’re not practiced with driving it.
    What are you trying to accomplish with the Summit?

    I am running a Mamba Monster combo in mine with no issues.

    Question I asked myself before and I ended up with a 40mm X 82mm brushless setup . . .




    Unfortunately it was too long to fit as the existing 775 motor . . .




    But since I got this Summit used, the previous owner had installed a bual motor mount and I was able to install it facing the opposite direction which worked out fine . . .



    Of course there are other things that will come up due to such a massive upgrade in power . . .

    Yeah for sure! I have upgraded the diffs with the LEM diff cups and gears and a ton of other things.

    Too bad traxxas doesn't make a plate/cover like that for the ERBEv2... I wouldn't mind a larger motor in that. I have the same system in both my outcast and erbev2 and the erbev2 geared for lower top speed still runs warmer. Even when I ran 3.8 trenchers on both. Maybe I'll pick up another set of backflips for the ERBEv2... lighter tire should help. Just odd that it runs warmer as it feels lighter than my outcast.
