Hello, I'm not a specialist, but I'd like to answer your question. As this brand does not specialise in RC and is not aimed at enthusiasts who compete, to my knowledge there are no spare parts available specifically for this model.However, depending on the part to be replaced, it is possible to obtain parts from other brands in specialist RC shops or from specialist online sites* (see below). if there is a reference number or brand name on the spare part in question).
It is possible to repair or reinforce certain plastic or metal parts with two-component epoxy resin.
Also, depending on the characteristics of the part to be changed, it is possible to upgrade plastic parts with other metal parts (differential, gears, etc.). Note that if you opt for a metal upgrade, such as a differential, the drive shaft must also be changed.
*For reasons of the non-competition clause in the comments, I don't think I'm allowed to give you the names of the sites.
