You just need patience and practice. If you don't run your car in different conditions, you can't tune proper when you need to. It's like this, if you only race you don't get enough practice( tuning or driving ) you won't be able to do it when you need to. When i was slotcar racing, If i missed a week of practice, i needed an hour to get right or i couldn't keep it off the wall to save my life.

What i'm tring to say is you need to play with it when you can, so you can race when you have to. Just don't let it affect your school studies, this should be your top priority
