    ESC/Motor combo suggestions for Trail Running.

    Hi

    I have a Summit VXl and I'm really enjoying it so far but I want to make it it a little more suitable for Trail Running.
    I Plan on flipping the transmission, shimming the diff and locking or adding heavier weight oil. but I really want a new motor and esc I'm leaning towards a brushed system. any help and advice most appreciated.

    For "crawling" brushed or sensored brushless is the way to go... as to what specific system... that depends on your wallet.
    Whatever it is I just said... I could be wrong.

    Ideally I would like to keep the cost under $100 so it will have to be brushed. What will I have to change out to run a 540 motor?

    $8 Motor Plate (7380)
    $4 Gear Cover/Hardware (7379)
    $10 Motor Mount (7360)
    $10 Rx Cover (7024x)

    This is a picture of the difference in Rx covers:

    New style (for big block) is on top.

    All these prices are fore NIP items... if you go to eBay, I imagine you can find the whole set for $12-15.... I have, anyway.

    If you are doing trail running dont flip the tranny gears. The top speed will be not to your likeing. For slow rock crawling it is nice but on open fields you will regret the loss of speed. Even if you run a system which can handle more lipos you will find the gearing "quirky and jerky". I did the tranny flip in my first summit - is was a great -slow - technical rock crawler. But my son had a stock summit - I knew his speeds where far greater than mine, but it was simply no fun anytime the trail opened up. Just could not get up and go. At high speeds (18mph est) is was very loud and whiny - seems as though is was always struggling to max itself out. I eventually purchased a second summit for normal usage. I would suggest an upgrade in brushless system and gearing for more torque. A Mamba Monster Pro (mmp) is a great option. They run $120 (used can be had for $80) and motor options are limitless (sensored/sensoreless/brushed -stock vxl/ -stock titan) . In truth I always ran it on a brushless sensored motor, but as a trail runner /rock crawler the stock titan would probably be a very nice combo.

    I recommend flipping the gears to everyone. With the vxl it can still be geared fast and control temps better. Have you the 380 2.5xl on standby to drop in when you want better speed control for harsher terrain.
    I have a rig set up just like this, 100k in the diffs. In brushless it's geared 26/50 on 3s temps are always good back flips front flips big jumps guessing maybe 25-35mph. Five minute motor/esc swap geared 13/50 top speed is 3-5mph but a single stock nickle batt runs for an hour!
    Little help!)

    Sounds like a plan, I was thinking of dropping in the 380 2.5xl, what gearing do you recommend?

    Just flipped the gears and it has made a noticeable difference the car climbs a lot better and I'm not missing the speed. I just need to put some 100k in the diffs now.

    Sorry to thread jack. But how do you flip the gears in the tranny?
