I bought a maverick strada mt (brushless) for my son for Christmas and he has used it 3 times each time seems to be shorter and shorter and occasionally the car just does not seem to respond to the remote I want to make it run faster and for longer because it seems to run a little slower than I expected it to and my son is a little bit disappointed with the car can anyone give me any advice please? I'm new to this so not sure what I'm doing I also want to find some upgrades for it to make it more durable and make it stand out
