1/5th Scale Petrol General Maintenance Advice Request

[Strutter]

I've got hold of a 1/5th scale petrol TQ Monster Truck and am looking forward to many hours of fun. However, I know nothing about how to maintain this new vehicle. Instruction manual translated from Japanese and not very helpful. Am looking for practical advice on what I should do before / after every run and less regular maintenance. Have failed to find an appropriate textbook. Any advice would be hugely appreciated.
