    I've been running a 3S 6400mAh 65C lipo from full to cutoff followed by a 3s 5000mAh 25c lipo, bashing and jumping in 28 deg C ambient. Maybe my esc has better thermal transfer between components and...

    Ah that's awesome, I'm totally doing it. Tubing direct to motor is a great idea too. Thanks for the inspiration!

    Or you could cut a scoop in the bonnet (hood) for better looks and probably better airflow.

    At 11/54, I just ran my full 3S pack on jumps and gravel with ambient temperature of 26 deg C and motor topped out at 55 deg C after the hardest continuous run. Happy with this combo for now :)

    I actually don't know what you mean by 'drive guard' (center shaft maybe?), but regardless, don't forget to add a dab of loctite to stop it happening again :)
    Well done and happy bashing!

    With this new info in mind, that should be enough I would think. Thinking of the Stampede specs, it appears the motor draws a theoretical 200A max (iirc;someone correct me if i'm wrong!) but...

    I did say to take my post with a grain of salt.. As I understand it, cell count (eg. 2S or 3S) multiplied by C value gives you discharge rate. I didn't say anything about capacity. By 'performance' I...

    I use a 3S 6400mAh 65C-130C LiPO battery. It cost about AUD$45. I also use a 2S 80C hardcase 5800mAh pack with my stampede. I own about 12 batteries of the same brand and all have performed within...

    Regardless, a 60A-capable 3S battery is probably a bit too small for the Stampede, at least if you want it to last a while without puffing or failing. Why don't you try running it in the dry to see...

    Water shouldn't bother the lipo. Remember, if oxygen contacts the lithium you get fire, so if it's airtight then it's waterproof. The contacts on the balance lead shouldn't be a problem but if...

    Pull the wheels off and check the hexes. Likely culprit if they're plastic and wheel nuts are not checked for tightness.

    Remedy is to buy aluminium hexes and use loctite when tightening those...

    Glad it's working properly. I'd have thought taller gearing (13/54 instead of 9/54) would be hotter rather than cooler as the motor pulls more current during acceleration in this configuration.

    Taller gearing and more traction means the motor draws more amps, making more heat, requiring more cooling to keep the stock VXL system happy. The trenchers bring both taller gearing and more...

    It'll wheelie on nimh batteries. Remove the spur and slipper unit, tighten the slipper nut holding the spur with your fingers (ala 'finger tight') then back it off 1/8 to 1/4". Wheelie away :)

    I run 2.8 trenchers and a beefy 3S 6400mAh battery. I have a heatsink and fan on both motor and ESC (stock VXL system). Got too hot with 11/54 but 9t pinion is great, only gets warm to the touch, and...

    I don't know the specs but as long as they're 2.9 to 3.5v and up to 20mAh draw per led I'm sure they'd be fine. I'm guessing, but it's an educated guess and you certainly won't hurt your receiver if...
