Hardened steel ball driving set for 1/5 and 1/6 all models, width 390 mm.

This system is a further development of the normal pen system. Because the bullets can slide into the wheel- and differential axles creates a very flexible working drive that provides minimum friction at any angle.

The wheel- and differential axles have 6 recesses, after wear you can use the other slides to make a brand new drive set. In older models, we advise to replace the existing rear wheelhubs, so the drive shaft covers can not rub along the lower wishbones.

The order numbers are:

• Plastic FG6077
• Aluminium FG6478
• Aluminium FG6479
