NOVAK GTB 4-CELL - INSTRUCTION ADDENDUM Instruction

This Addendum should be referred to instead of the included original

instructions for the following changes which are noted below.

The GTB 4-Cell was designed for use only in lower-load applications where

only 4 cells are used such as oval and 1/12 on-road cars.  Use with more

than 4 cells or in higher load applications like touring cars will void the

warranty as seen in the main GTB instruction manual included with

this product.

SPECIFICATIONS:

All specifications are identical to those found in the GTB Main Instructions

except for the following:

Input Voltage ..............................4 Cells (1.2 Volts DC/Cell)

ESC Weight (w/o wires).............1.01 ounce (29 grams)

PROPER GEAR SELECTION Starting Points:

Gearing is given in rollout for each brushless motor turn (i.e. 4.5).  Rollout is

determined by dividing tire circumference (tire diameter x 3.14) by spur and

pinion gear ratio. Example: (1.75” x 3.14) ÷ (100 ÷ 23) = 1.26 rollout.

For optimum 4 cell performance, it is not recommended to exceed

temperatures of 160˚F (71˚C) on the ESC or Motor. Reduce gearing if

necessary.
