crawlster®BTA2-SCX steering system – Axial SCX10.1

crawlster®BTA2-SCX – the unique BTA steering system for all Axial® SCX10.1

  • HD-Carbon – low weight = low center-of-gravity (LCG)
  • Fixes negative steering angles and improves the steering geometry / performance by positive Ackerman-effect. Maneuverability and off-road ability are clearly optimized
  • no steering bar in front of the axle - optimized banking angle
  • up to 100% drop deployable – allows 4-link suspension
  • TUNING-KIT incl. 1 x crawlster®BTA2 steering bracket, accessories for mounting to Axial® HighClearance knuckles (AX30526) plus TRX-RodEnds for Servo-linkage
  • 2 x crawlster®TUNING-Sticker – detaillied mounting instructions
  • ATTENTION: Mounting only (!) on Axial® HighClearance Knuckles  (AX30526) 
  • NOT suitable for SCX10.2  (AX90046)

crawlster®BTA Button STEERING

Optimized steering geometry and dramatically improved off-road maneuverability

  • Unique BTA steering system – innovative concept to realize a „behind-the-axle“ articulation
  • For all AX-SCX-1/10.1 serial front axles with HighClearance knuckles
  • Immediate & dramatic improvement of steering geometry / performance
  • Fixes negative steering angles – now the inner wheel steers ≥ zero / more than the outside wheel
  • Positive Ackerman steering geometry 
crawlster®BTA Button SIMPLY

The crawlster®BTA2-SCX steering system can easily be installed by anyone

  • No complicated reconstruction
    such as lifting the servos necessary
