GATES for BestTrack
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.

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.

VAC, double-insulated construction, optical coupling.There is
no electrical path from power back to the triggering devices,
or computer circuits.
Ledex Size 5S, Model H-2527-032, operating 10% duty cycle, starting
torque 6.3 inch pounds.

GRB and GRB-D solenoid gates.
The Model GRB
may be activated in three different ways:
Switch Model PB-3 $29
Tree Model LT3 $169
Control Interface, Model SCI $39
Available. If you have special requirements, please call to discuss.
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.
GRB now has a big brother!
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.
