    So the big 6S 8000mah Zippy Lipos have apparently been discontinued due to shipping restrictions. Problem is, I need to replace the batteries on my first two builds and it is a very specific fit when it comes to the form factor. So my solution is to combine two 3S 8000mah batteries in series...

    Strong, waterproof parallel triple unions: How to

    Not sure how anyone else does this but I have found a way to make strong, waterproof, triple parallel unions for 10AWG silicon insulated wire. Better yet, it uses supplies that can be sourced at Home Depot (mostly) and tools that you likely already have if you have been doing any of your own...

    power loss and backward rolling residence. HELP!

    Edit: So I fixed the 3-speed switch and noted a new symptom; backward rolling resistence (a lot) when the controller is powered up and none when it is powered down.

    Quick e-brake question

    I'm getting ready to convert my hydro brakes to e-brakes via a reed switch. This seems pretty straight forward to me but I want to use a micro-miniature switch and I am not sure about the current necessary. I know that the brake operates off of 5V but how many amps? I was looking at switches...
