    It's not just about the motor. More importantly, it's about the ESC. What ESC is installed?

    We're gonna need some more info. What exact motor are you using? Also are you using the stock esc or did you upgrade that as well. If stock esc then you can't run over a 3 cell lipo, even if the motor can take more.

    Looking at Hacker RC's site, it looks like most of their wears are made for flight applications and not for ground use. Plus, none of their specifications have any translation over to what we'd commonly use, such as number of turns or KV rating.

    What specific motor are you planning on running, and what is it's KV or turn rating?

    What ESC are you planning on running with this motor?

    I didn’t see anything called a skylark on their website but everything on there looked to be for airplane use. Especially the ESCs. Hopefully you got it cheap enough that you can replace the motor and esc with the correct stuff, that’s what I’d do.

    Hacker motors were popular years ago in car and trucks may be an older model. We need to know the can size and kv.

    Did you calibrate the ESC to the TX?

    Well, we need to know exactly what esc and motor you are using and exactly what reciver/radio combo you are using.

    If it's a brushless motor that is senorless, take any two of the three wires and reverse them. Then there should be a switch or a mode on your transmitter to change throttle direction.
    Basically the esc sees the motor going in reverse. Going in reverse the esc will be giving only 50% power in most cases.
