The Maverick Strada DC is a rebranded HSP Flying Fish, all the parts fit except the chassis is different. This guy sells alloy hop-up for HSP cars on eBay UK and most will fit the Strada, available in purple/blue/silver and not badly priced.
He does metal spur/pinion combos which I may purchase for my brushless DC
You can pretty much "alloy up" the Strada for the price of a decent bodyshell.
