Airstar produces a number of upgrade parts
to improve your Vario helicopters. All parts
are made of aviation grade aluminum and
available powder coated or anodized in a
variety of colors.
We highly recommend that you replace the
standard plastic Vario blade grips with the
CNC aluminum versions. The plastic grips are
known to have failed in flight on heavier
scale helicopters.
