T37 Racing Upgrade Racing Sloop

T37 Nationals 2011  The T37 Racing Upgrade Racing Sloop features a variety of innovations to allow for precise sail adjustments, faster sail trim, and improved speed and performance.

The mast and booms are made of strong, light-weight carbon fiber. The double-throw sheeting system, along with the more powerful ultra-torque sail servo, makes sail adjustment even faster and easier and the boom-vang helps to maintain a perfect sail shape. Whether you are racing in a fleet of 20 boats or a fleet of one, the speed, agility, and beauty of the T37 Racing Upgrade Racing Sloop will provide hours of sailing fun!

Like the standard T37 Racing Sloop (and all of our RC kits), the T37 Racing Upgrade Racing Sloop includes all of the parts except for paint, varnish, and double ‘A’ batteries!

The kit comes with:

pre-cut okume marine plywood hull and deck pieces
high-quality brass and stainless steel hardware
high-tech Spectra rigging lines
carbon fiber mast and booms
3/4 oz. nylon spinnaker cloth pre-sewn sails
marine-grade epoxy, along with epoxy brushes and syringes
full radio control gear, including the transmitter, receiver, and battery box
sail and rudder servos, including the strong ultra-torque 645 sail servo (to upgrade to the digital 5645 ultra-torque servo, see option below)
Detailed instructions to guide you through the entire building process
… and more!
