The Bingo Wasp MAX AWB RDX chassis is essentially installed the same as the standard Wasp MAX chassis but you can easily change the wheelbase by loosening 4 screws, sliding the rear chassis to the desired position, and then tightening the screws again. You can fit bodies with a wheelbase of 225mm to 274mm, like the Kyosho Fazer bodies, which typically have a wheelbase of 274mm, or any real-grade bodies with longer or shorter wheelbases than the standard 257mm. With the optional Xtra Long slide plate, you can extend the wheelbase up to 324mm and mount Traxxas 4-Tec bodies which have wheelbases that go up to 300mm!
