Bingo RC DesignsBingo Wasp RMX AWB Chassis – Forged Purple BRC-RMX-AWB-FP
The Bingo Wasp RMX AWB Chassis is designed as an upgrade for the MST RMX 2.0/2.5/M drift car chassis. The new AWB Chassis (adjustable wheelbase) allows a larger variety of bodies to be used on the chassis.
The AWB supports a wheelbase of 225mm-274mm, and with the optional Xtra Long slide plate, you can go up to a wheelbase of 324mm! The Bingo Wasp RMX AWB chassis also brings significant weight reduction which will make the car feel much quicker. It also can increase the flex and grip of the car. There is also an additional battery placement option, allowing the battery to be moved further back for more traction.
Wasp MST RMX AWB Chassis Instructions
1. Upper Brace Assembly
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 piecesin the picture. The M3 press nuts should be on the inside of the brace.
2. Assemble one side first
Assemble one side first, using 4 of the M3x8 FHS screws as shown.
3. Add standoffs
Loosely attach the 4 x 10mm standoffs.
4. Attach other side
Attach the brace parts from the other side and loosely tighten the screws.
5. Attach upper brace to front
Attach the upper brace to the front bulkhead using the existing screws that were holding the stock brace. The AWB has M3 press nuts embeddedin the carbon fiber (no longer requiring M3 lock nuts).
6. Attached upper brace to gearbox support
Attach upper brace to the gearbox mount using the stock screws. The 4 screws should go into the AWB upper brace M3 press nuts.
7. Alternatively use brace extensions
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.
8. Brace extensions
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.
Steering Servo Positions
Transverse Servo
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)
Front Inline Servo
The steering servo can be mounted inline with the chassis, on the front plate (e.g. RMX-M)
Mid Inline Servo Spacer Plate
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.
