RE: FG BEETLE PRO REBUILD THREAD(my style)
i think you should run it first untill you really need an upgrade!!
my first choice of upgrade then would be the diff mounts and diff case converted to alloy to cope with the stress,second would be steel gears with alloy spur adaptor.
transmittor/reciever radio gear/servos & battery pack must all be of good quality,if you got an either futaba 3pm or spectrum dx3.0 like me they come with built in failsafes also to prevent runaways!!
these would be my very first vital upgrades to make your hummer bulletproff,after these its a matter of waiting for the parts just to wear out first.
obviously there is a whole whost of parts that can also be upgraded later on to make it much more sturdier.
but in stock form you should be fine for a long time if you watch screws and retighten after running with some blue loctight threadlock.
so have you bought it or waiting to?
