A stadium truck is 2wd and has low ground clearance while a monster truck is 4wd has high groung clearance. I have a rustler vxl witch is a stadium truck and I have an e-savage witch is a moster truck.
not all true
there are a handful of 4wd Stadium trucks, mostly HPI makes them but there are some. Reason they are still a ST, and not a truggy, is due to not having a center differential.
Thing is some "Monster Trucks" (Revo I'm looking at you) are basically stadium trucks, or truggies, with gigantic tires on them.
Most true blue monster trucks have fairly high centers of gravity and will flip super easy if you take a turn too fast.
VS a Stadium truck being able to take a turn usually going near full throttle without flipping.
Monster truck has ALOT of ground clearance, vs a stadium truck generally is lower to the ground like a buggy (ST's are a little higher off the ground than similar scaled buggies) and have more buggy like characteristics.
Then theres Truggys which are essentialy buggies with truck tires flung on em
