Treaded traction device and system for model vehicles

A treaded traction device for a model vehicle comprising:

• a tensioning assembly comprising:
• an idler wheel;
• a first tension support member pivotally coupled with the idler wheel and pivotable between a first tensioned position and a first untensioned position;
• a second tension support member pivotally coupled with the idler wheel and pivotally coupled with a treaded traction device structure supporting a drive wheel axle;
• a tension securing device for releaseably securing the first tension support member in the first tensioned position;
• wherein the second tension support member is pivotable between a second tensioned position and a second untensioned position;
• wherein the idler wheel is rotated away from an inner surface of a surrounding tread when the second tension member is pivoted between the second tensioned position to the second untensioned position facilitating removal of the surrounding tread.

A treaded traction device for a model vehicle comprising:

• a biasing assembly comprising:
• a first bias support fixed relative to a vehicle hub;
• a second bias support fixed relative to a traction hub;
• a coil coupled to the first bias support and the second bias support;
• and
• a dampener member coupled to the first bias support and the second bias support;
• wherein the treaded traction device is biased such that a first end of the treaded traction device is positioned lower than a second end of the treaded traction device when unloaded.
