I have both of these trucks and they're tough for sure.The front diff on the Savage is a pain!...The shock towers and PLASTIC braces for them on the RTR Hellfire need to be replaced,one good hit and they're gone.I also broke the steering servo gears,then upgraded to metal gears.For spares get some A arms & dogbones.Might want to check the diff housings,mine were dry,no grease on the gears.Here's a front skid plate:[link]http://www.neweramodels.com/item.cgi?session_id=&part_id=2981[/link] ,they also have a small rollbar.The large HPI wing will help take some abuse from bad landings,I put one on when the one on the body gave it up.I also geared up w/a 16 tooth bell.

I still think the Savage has it in overall toughness,but can be a handful when driving on the edge.The Hellfire is WAY easier to drive.
