BASIC
OPERATION
●
The VPC MongoosT-50® Base is compatible with the VPC Extensions. Extensions up to
150mm are supported, extensions larger than this are not recommended, especially when
combined
with
heavier
springs.
●
The VPC MongoosT-50® Base should be mounted with the included VPC U-Bracket. If this is
unsuitable, a custom mount can be created to connect directly to the existing 4 x VPC
U-Bracket mounting points. Different length screws should be used to account for the
difference between the original VPC U-Bracket and any custom solution. It is not
recommended to mount the base via the underside bolts. Any damage caused by a custom
mounting
solution
is
not
covered
by
the
standard
warranty.
●
When adjusting the spring loading screws via the upper plate adjustment holes the minimum
allowed tension is when half of the joysticks deflection is free of any spring force. The
maximum allowed tension is achieved by roughly 25 clockwise turns. Over tensioning the
spring loading screws can result in the joysticks total deflection being limited. If you require
stronger
spring
tension,
replace
the
axis
compression
springs
for
the
heavier
set.
●
The VPC MongoosT-50® Base is a complex piece of equipment aimed at the experienced
user. Replacing the springs and cams can be a complicated process and if you are at all
unsure, please contact VPC directly for help to avoid damage to your set. User damage while
attempting to make adjustments to the base is not covered by the manufacturer warranty
and
would
be
subject
to
a
repair
cost.
