I’ve got a Neo Fighter, which is pretty good.
To be honest though, if I was buying again I’d buy something with a bit more ground clearance so it copes a bit better on grass.
The Aqroshot is basically the Neo Fighter buggy (DT03 chassis) with bigger wheels. The only difference is the wheels and the front steering knuckles have longer shafts for mounting the bigger wheels. I keep thinking of converting mine, but Tamiya spares are a bit pricey….
Regarding the Grasshopper – a mate had one & I just remember it bouncing all over the place as the shocks only have friction dampers which don’t seem to actually do anything.
