START
GATES for BestTrack
Model
GRB
|
Description
The GRB
is a full-motion mechanism specifically designed for the BestTrack
Pinewood Derby track. It operates by remote control to start
your race with nobody near the track. The GRB mounts with a
pair of 1/4"-20 bolts included, using the same captive
bolt system as the rest of the track construction. The electronics
portion of the integrated unit is contained within the cavity
of the track.
The actuating component
is a powerful rotary solenoid which pulls the BestTrack's gate open by a
brass pull rod. You must drill a small hole in the peg bar to attach the
pull rod. Diameter 3/32", located so that the pull rod loops within
the bolt channel.

The springs
of the BestTrack are reversed from their normal anchoring point
uphill from the gate, to points downhill.
Attach power and triggering
cables, and you are ready to race.

One often requested
modification is the ability to trigger the light tree from within Derby
Management sofware in addition to the standard infrared remote control.
When the light sequence gets to green, the Light Tree in turn activates
the gate. This modification involves work on the Light Tree, the Gate, and
and the interconnecting cable, and adds $20. Order the GRB-D at $199 and
the Light Tree Model LT3-D at $179.

New!
The
GRB now has a big brother!
Weighing
in at 2 pounds, 10 oz, and generating three times the torque,
the GRBB is not needed for 6 lane BestTracks, but could be considered
for 8 lane BestTracks and above. Or for unlimited class races
where heavy cars are allowed.
It mounts with four
bolts, otherwise everything works the same. The heart of the GRBB is the
Ledex Size 7S, Model H2809-027 with 17.5 inch pounds of starting torque.
The GRBB and GRB are shown at the right for comparison.
See a video of the GRBB
HERE.
GRBB is in stock at
