It works hard

Very strong.
Correct product for the price and even a step above.
Try with a battery of 8.4v and you will see a power boost;)
But it remains in the recreational leisure, nothing to do with market models (Hyper7, Kyosho, etc ...) but for the price, I find this very correct. => Not to use a real club circuit, a lot of plastic, which in my opinion would not stand after a few jumps.
But again, it's not bad at all
