info E-firestomr parts

[Lowie]

sorry for this simple question but I'm abroad and do not have a good internet connection, ... so no means to do extensive research.

I run a Firestorm-truck (HPI) and converted it to Brushless (mamba-set), so it is now = e-firestorm.

I intend on running it in competition and need some spares (asap).
Can someone give me advice on where I should be able to order all HPI-firestorm-parts that can be shipped worldwide (to Belgium), and if possible, within the week?

thx for all info!
