Although great for first time users, Helion RC products are indeed advanced radio controlled vehicles with sensitive electronics and
moving parts capable of causing injury if used improperly. Always use caution and common sense as failure to operate your Helion
RC product in a safe and responsible manner can result in damage to the product or other properties. Therefore this product is not
intended for use or maintenance by children without direct adult supervision. Helion RC and your hobby dealer shall not be liable
for any loss or damages, whether direct, indirect, special, incidental, or consequential, arising from the use, misuse, or abuse of this
product or any product required to operate or maintain it.
• Do not operate your vehicle in rain, electrical, or thunder storms.
• The vehicle should never be turned ON without the transmitter being turned ON.
• Never operate your vehicle when with low transmitter batteries.
› Indicated by flashing LED on the transmitter.
• Always check for proper radio system operation (steering and throttle) prior to letting go of the vehicle. If the vehicle does not
respond properly to transmitter input, turn the vehicle OFF and inspect all connections and operating environment. Also see the
Troubleshooting guide in this manual.
• Optimal enjoyment and safety will occur in a dry (no puddles), open environment away from traffic, and cars (never run into the
street for any reason).
• Always turn off both transmitter and ESC and disconnect the battery from the ESC after use.
• Exercise extreme caution when touching the motor and battery connectors immediately after running your vehicle, they may be
HOT and cause a burn.
• Always allow the motor in your vehicle to cool before using again.
NOTE: Only use genuine replacement or aftermarket parts available from your local hobby dealer to ensure proper opera-
tion of your Helion RC product.
General Care:
• Always use clean, dry cloth or soft bristle brush to clean your equipment.
• Never use chemical cleansers to avoid damage to the sensitive electronics and plastics.
Maintenance:
We want you to enjoy your product to its fullest potential. For this to happen it is important to keep your product clean and properly
maintained. Lack of cleaning and maintenance can cause component failure. For best and continued performance from your product
it is recommended to briefly inspect your product for damage every few runs. Typically, a good time to do this is when changing the
battery or while it is charging. If a problem is discovered, stop use immediately and perform repairs or seek assistance. Continued
use of failed components can cause more unnecessary damage to your product. Always remember to use genuine replacement
parts from your local hobby dealer. Below is a list of items for inspection. Inspection should not be limited to this list; if you notice
any problem, listed or not, it is recommended to give it proper attention.
1. Electronics: Although the ESC and servo included in your vehicle are waterproof the receiver is not, however it is contained in a
water resistant box. It is recommended that you avoid submersion of the vehicle however light running in puddles and light rain
should not be damaging. If you plan to run for extended periods of time in light or heavy rain It is recommended to secure the
receiver in an additional waterproof membrane. Since the Helion HRS-3.1 receiver is a micro size receiver, fitting it into a balloon
is fairly easy. Simply insert the receiver with connected wiring into a balloon and secure the balloon around the wires with an
additional rubber band as close to the receiver as possible, allowing the most exposure of the antenna as possible.
2. Antenna: To achieve full operating range with your radio system, it is critical that the receiver antenna be installed properly and
undamaged.
a. Inspect any exposed antenna for cuts or abrasions.
b. Ensure there are no kinks in the antenna or antenna tube.
c. Never fold the end of the antenna over the tube, this will reduce the range and damage the antenna.
d. Ensure the antenna is not being pinched by the set screw that holds the antenna tube in place.
3. Gears: Periodically remove the gear cover to clearly inspect the gears and ensure there is no debris in the gear compartment.
a. Proper gear mesh setting is crucial for proper operation and life of gears in your product. It is important to have the pinion
gear (attached to motor) as close to the spur gear (attached to drive shaft) as possible yet while providing a minimal amount
of backlash. Backlash is the rotation one gear has to make before contacting the other. Having the gear mesh set too tight
will cause excess load on the electrical components and may cause premature failure. Having gear mesh set too loose will
cause excess wear and possible skipping of teeth during operation thus causing excess wear and premature failure.
b. Checking the gear mesh and setting proper backlash.
i. Remove the spur gear cover.
