Wasp MST RMX AWB Chassis

Please see the MST RMX chassis install for an overview of the basic chassis conversion. The MST RMX AWB install is similar, but the upper brace and main chassis deck are made with multiple sections. Each side of the AWB brace is made up of 3 pieces, front plate, middle slide plate, and back plate. Note the orientation of the pieces in the picture. The M3 press nuts should be on the inside of the brace.

Assemble one side first, using 4 of the M3x8 FHS screws as shown. 

Loosely attach the 4 x 10mm standoffs.

Attach the brace parts from the other side and loosely tighten the screws.

Attach the upper brace to the front bulkhead using the existing screws that were holding the stock brace. The AWB has M3 press nuts embedded in the carbon fiber (no longer requiring  M3 lock nuts).

Attach upper brace to the gearbox mount using the stock screws. The 4 screws should go into the AWB upper brace  M3 press nuts.

Alternatively you can remove the gearbox mount and use the brace extensions to attach the upper brace directly to the gearbox.  The brace extensions allow the motor to be mounted high, and the battery can be moved rearward.

The 30mm screw will go into a press nut on the left side extension. For the longer 40mm screw, use the 3mm spacer on the head and then put the .5mm and 9mm spacer on the left side, between the gearbox and the motor plate. Note it will be easier to install the .5mm and 9mm  spacers if you loosen the motor plate screws to provide ample space for installation, then tighten down the motor plate and gearbox screws.

The chassis length can be adjusted by loosening the 4 screws on the upper stay, and the two screws on the rear plate, attached to the slide plate.

Adjust to the desired length then tighten all the screws on the upper brace and rear plate. Make sure the front and rear plates are aligned and straight. Also make sure the front and rear plates are level when tightening the upper stay. 

The Wasp RMX AWB chassis supports 3 different steering servo locations. You can mount a server transverse to the chassis (e.g. RMX 2.0)

The steering servo can be mounted inline with the chassis, on the front plate (e.g. RMX-M)

The servo can be mounted mid chassis. To support this there is a servo spacer plate included. This will allow the servo to be mounted on the slide plate.

The mid inline servo placement is typically found on the RMX 2.5.

The Xtra Long Slide plate is an optional accessor that allows the Wasp RMX AWB chassis to extend to wheelbases beyond 274mm. Kyosho Fazer bodies typically use a 274mm wheelbase. Traxxas 4-Tec bodies range from 288mm to 300mm. An extreme setup is using a Hot Wheels cybertruck body which uses a 324mm wheelbase!

This shows the Xtra Long Slide Plate at it's maximum length.

Custom modifications to the Hot Wheels Tesla Cybertruck body to have it drift using the Wasp RMX AWB chassis.

Using the Wasp RMX AWB chassis, 324mm wheelbase. 

The Traxxas '35 Hot Rod Truck body will fit on the Wasp RMX AWB chassis with a 300mm wheelbase.
