More new options have arrived!!! from Five Star...those into GP will know these are "Big Boys" in the quality department.
Alloy suspension bellcranks running bearings.
Alloy Steering bellcrank.
Delrin pivot ball guides
Delrin lightweight diff outdrivers.
All are excellent quality.....but damn expensive!!
Tobee craft have released lightweight main drive shafts.......but personally I think the 3 Racing set is cheaper AND better quality!!!
