If you can save up to bu a Firestom, I highly recommend you do. HPI parts, replacement spaers, and optional hop-up as well as many aftermarket options are caied by virtually every local RC store.For example, you can just about walk into any HobbyTown USA and find all the HPI screws, bolts, and replacements you need. Additionally, Hobbytown USA also caries a ton of optional aftermarket parts for most HPI products.
