Fuel is the most critical component for making your engine perform
properly. Improper fuels will cause hard starting, poor performance,
and excessive wear on the engine. Fuel for your vehicle must
contain a blend of BOTH synthetic oil and castor oil. Use a high-
quality blended fuel. We only recommend Megatech’s High
Velocity Racing Fuel or another premium quality car/truck fuel with
25% Nitro content.
CAUTION: ALWAYS FOLLOW THE PRECAUTIONS PRINTED
ON THE CONTAINER OF FUEL. KEEP IT AWAY FROM OPEN
FLAMES AND CHILDREN. THE MIXTURE IS FLAMMABLE
AND POISONOUS.
Your Dark Thunder features a competition fuel tank and priming
system. The tank uses a spring-loaded ller cap over a wide ller
neck for fast, easy fueling. Simply pull open the lid and it will spring
closed when you remove the nozzle. Remember to use a fuel ller
bottle with an attached long nozzle that can be inserted into the ller
neck. Never pour fuel from an open can into the tank or use a funnel.

Your Dark Thunder comes fully assembled and nearly ready to race right
from the box. Very little setup is required, however, proper
preparation is crucial to maximizing the performance and enjoyment
of your vehicle.
First we do recommend that you
tighten down all of the bolts, as they
may have come lose in transit. Be
especially careful with the engine
mounting bolts as shown in
Figure 3. Because the engine has
such high RPMs, it is important to
make sure the bolts have not
vibrated loose after every use.
