already on the verge of giving up need inspiration

[nivlacf1]

so been running touring cars since beginning of the year spend hours researching asking questions then setting up the car only to put it on the track each week and there is another unexpected problem i think in all this time my 2 kids have maybe completed 6 to 8 races between them, it so frustrating spending time and money setting the car up to not get one full race, each time you think this is the week i've sorted it now something new pops up and damages the race, i'm not expecting them to be competitive yet but just one night of full races would be good i am so close to giving up, please tell me these are newbie teething problems and they will go away!!!
