1. Refer to the ESC Guide and set the
ESC jumper to LiPo battery. Properly
dispose of the LiPo battery, as it is no
longer safe to use
2. Replace the LiPo battery with a fully
charged, brand new battery. Dispose of
the bad battery in accordance to your
local laws.
1. Check if all ESC & connections are well
soldered and firmly connected.

switch.
2. Swap the two wires (black and red)
from the motor to the ESC.
1. Set transmitter throttle trim
2. Follow Quick Start Guide for proper
start-up sequence
Check the battery voltage and the ESC
temperature. Let cool and recharge
battery
1. Use another pack with better discharge
capability.
2. Use stock motor, stock gearing, and
don't pull heavy loads.
3. Reset gear mesh.
Tighten slipper clutch until vehicle moves.
Slipper should still slip when vehicle is
held still on carpet and given 25% throttle.
See Slipper Clutch Guide Page: 16
1. Reset gear mesh
2. Replace gears
1. Replace servo
2. Replace servo horn
1. Charge battery pack
2. Plug in battery securely
3. Follow Quick Start Guide for proper
start-up sequence
