Product Description: 110 RC Car Electronic Simulation Smoking Exhaust Pipe Upgrade Kit SpecificationFunction:Input power; 7.4V; max 1.3AControl signal input: front and back remote signal input (including 5V Power supply)Battery low voltage protection; if the battery voltage is below 6.0V, the smoky exhaust pipe will send out a short and long flame signal, and stop the smokeOil shortage overheating protection: when the oil is insufficient, the smoke will be thin; when the smoky exhaust pipe is overheating, the circuit will stop working and the smoky exhaust pipe will stop fuming. At the same time, the smoky exhaust pipe will set up out slow-flashing signal until the temperature drops.Flame simulation: The flame flashing frequency is higher as the throttle increase; when the generator is at idle, the flame flickering frequency is slow.Smoke simulation: The amount of smoke increase as the throttle increase; when in idle mode, only a little smoke is generated.Service time: One fill up can last 20 - 30 Minutes Instructions: Use the pointed mouth of oil bottle to align with the oil filler hole, and fill up about 1ml oil. Be caution that, do not let the oil leak from the gas orifice when filling up oil, because too much oil will slow down the fuming speed. Use the rubber plug to stuff up the oil filler hole after filling up oil.Find a proper location and secure the Smoky Exhaust Pipe to the body of the vehicleInsert the balance plug of the 7.4V battery.Insert the remote control signal line and at this time.
