Well I can tell you from experience.
You put a spool in the emaxx or lock any other trucks diff solid.
They really start turning like crap.
As far as locking the diffs in at speed.
As long as the tires are spinning at same speed.
There should be no issues.
I haven't seen where they posted a speed of the truck.
I would guess it should still be close to 30 mph.
The 775 motors was more powerful and faster then 2 550s.
Suspension is revo design with hi travel rockers and higher rate springs to accomendate.
It is not a rock crawler. It is not a racer. I don't do either so to me.
This FREAKING THING ROCKS!!!
The trans has a gear ratio of like 1.8 to 1 hi
4.0 + in low to one.
Where else can you get a truck to run 25 mph (not sure of top speed)
Then go hill climbing or woods bashing.
I see my next RC truck.
