    Heya, I bought an hpi sprint 2 sport not too long ago.
    Now it being stock [Minus front motor conversion for drifting],
    Would this be a suitable motor?
    HobbyWing JS2 Sensored Brushless Car Combo w/ Justock 45A ESC+XERUN-10.5T 3300kv Sensored Motor for 1/10 & 1/12 On-Road Racing/Drift Car Competition (ROAR Approved)

    Now at the moment, I'm just running the old NiMH batteries, and plan to upgrade to lipos.
    Curious as to what people may think of this product / products like it.

    Thanks in advanced :D!

    Turnigy TrackStar Waterproof 1/10 Brushless Power System 3520KV/80A (USA warehouse)
    Dribble recommended this to me and so far it's been super great and for the price , you cannot beat it. works just as good as the high end brands

    I love my trunigy TrackStar brushless setups. I have a few different ones and been running them for sometime with no issues. Cant beat the price and work great.

    Well, I can't driver, so I don't get to go to the races anymore like I used to. If you can give me the drive ratio from the spec's on your truck. I can try and figure it out for ya.

    Ok, its 4wd on road. Depending on how the track is set up, will largely determine how you gear. If its a tight track, gear low, like a 15 or so. If it is a large track with sweeping corners, then go with an 19 or so. With out seeing the track, its really hard to guess. But that's where I would start.

    That's a big track... I would start with a 19, and ask on of the other racers what they are running.
