For personal safety, it is strongly recommended not to disassemble the engine and start-up mechanism. If you encounter start-up problems, you can contact local distributors or TOYAN technicians to solve them. If you need to return to the factory for testing, TOYAN will provide you with full support after-sales, If there is a bad situation caused by private disassembly, you will bear the corresponding responsibilities and costs.

RS-S100X series requires a 1pcs special glow plug for a four-stroke methanol engine, which is started by using a 1.5-volt power supply. When the battery is disconnected, the heat retained in the chamber is still enough to heat the filament to keep the engine running. When the top center compression position is reached, an "automatic" ignition burst is achieved, while the spark plug remains at high temperature, allowing for higher rotational speeds while the load is
reduced. In contrast, if the RPM is low, the spark plug will cool, and if the RPM is too low, the ignition will stop, and then the engine will stop. Therefore, you can control the engine speed by adjusting the damper to achieve the best effect you want.

2. FUEL:
Please use quality guaranteed methanol model engine fuel. Self-dispensing or counterfeit fuel will greatly reduce the performance and life span of the engine. Since it is a four-stroke
engine, in order to ensure the normal operation of the engine, we require that only 20-25% nitromethane fuel can be used.
If high nitro fuel is used, the ignition time and cylinder pressure of the engine will be greatly affected, and the normal and stable operation cannot be maintained. When the nitro content of the fuel increases or the brand of fuel change , it is recommended to use oil-rich needle adjustments to run the engine so that the optimal setting for the new fuel can be rechecked,
(please adjust the ratio of gasoline fuel to 1:25 to 1:30, and use 2T engine oil).
If the engine is running at very high speeds and on high nitro fuel,The life of the spark plug does
not last long. Please note that engine fuel is toxic. Keep it out of contact with eyes or mouth and
always store it in a clearly marked container and place, and keep out of reach of children. It is
highly flammable. Keep away from open fires, overheating or any source of ignition

FUEL TANK: It is recommended to use a 100cc tank. The tank should be installed on the same flat as the engine. The gap between the fuel inlet & outlet of the fuel tank and carburetor should be kept within 1 cm (the carburetor must be higher than the fuel inlet & outlet of the fuel tank). If the gap is too high, the carburetor's working efficiency will be reduced and the engine will be started adversely. To ensure clean fuel supply, pls use standard 5mm silicone tubing and properly install oil filters. Since the engine itself relies on negative pressure to absorb oil, it is recommended the muffling exhaust pipe can be used to pressurize the fuel tank


RS-S100x series has been installed starting motor,we can achieve a one-click start, you only need to buy standard 7.4V 25C lithium battery to achieve rapid start-up.

Starting batteries with too low or too high voltage will not guarantee the service life of starter
motor. Do not use starter batteries with incorrect voltage.

Please start the engine in an open, airy environment to avoid discomfort from burning gases

Since the engine will produce some vibration after starting, please place it on a stable and flat

Since the engine has been cooled by a fan, high-speed rotating fan blades will be dangerous, do
not touch. If you find cracks in the blade during use, please replace in time
Every time you start the engine, please carefully check whether there are cracks in the blades. we
must replace new if any cracks to avoid the danger of blade spread out during high-speed


Make sure that the voltage of 1.5V ignition power supply is normal and the storage power is full.(No ignition power supply is needed when using three in one electrical regulation)
Make sure that the 7.4V universal battery voltage is normal and the storage capacity is full.


The prerequisite is adequate lubrication and cooling. The engine is run with very important oil
needle settings: The excess oil not only provides rich lubrication, but also conducts heat from the
surrounding metal and further assisted by the fuel nitro methane. the two-stroke model engines in pre-heating into the cylinder through the crankcase on a longer trip. But The four-stroke engine, with its intake pipe and carburetor mounted high on the cylinder cap, means that the rich mixture of cooling fuel and air will flow directly into the cylinder directly.With the help of fan cooling, it can provide excellent operation experience for every enthusiasts. You can also buy the TOYAN series of water cooling accessories, so that your engine will be able to maintain stable operation for a long time.


When leaving the factory, each engine has completed the needle setting. If you have adjusted the
needle during use, it is recommended that the pair of main oil needle be adjusted to 2.0 laps and
the pair of auxiliary oil needle to 1.5 laps. Since the methanol engine needs to keep the filament
temperature of the electric plug in order to realize ignition, when the engine is in the oil-rich state for a long time at low speed, the filament temperature will gradually decrease, resulting in ignition difficulties, so it is necessary to pull high speed oil at intervals to avoid oil-rich at low speed.
Since the four-stroke engine requires a large amount of air intake, it is very important to Set
the throttle-stop screw so that the minimum throttle opening (idle setting) is approximately 1.5mm. For the use of various engine enthusiasts, do not use strong force to twist the throttle
screw to adjust the size of the throttle opening. but to loosen the throttle screw and then pull
the throttle arm to adjust. As shown in the figure:


It is important to put the throttle in the right position before starting the engine. It is recommended that the throttle be opened at 30% to start, the engine is not allowed to open the throttle too far under "no load" conditions, which can quickly overheat and can seriously damage the engine piston ring and cylinder sleeve.Connect the spark plug battery and press the start button. Once the engine starts, disconnect the spark plug battery and keep the engine running slowly under the oil-rich needle setting. (If necessary, gently adjust the throttle lever to keep the engine idle steady. If the engine stops, cooling it for 15 seconds before restarting. Please hold down the start key within 5 seconds for each start, so as to protect the start motor life. Allow the engine to warm up for 30 seconds after starting so that the oil in the fuel can be fully lubricated to each working part. When the engine rapidly drops from high speed to low speed, or when low speed rapidly rises to high speed, the engine is unstable or the throttle control is slow or flashover, please confirm the carburetor working status:
When the engine has more fuel , smoke is emitted or accelerates slowly, indicating that the engine has excessive oil, please turn the main oil needle clockwise, 15° as a unit, gradually reduce the main oil needle, until the sound of engine exhaust is soft and strong, and the exhaust pipe slightly smokes and the lubricates fuel spray out
If the sound of the engine is too sharp, like the sound of dry friction between metals, the temperature rises rapidly, and the engine is stopped immediately after acceleration, indicating that the engine has low oil, please turn the main oil needle counterclockwise, 15° as a unit, gradually reduce the main oil needle, until the sound of engine exhaust is soft and strong, and the exhaust pipe slightly smokes and the lubricates fuel spray out
●Idling Stop
When the engine speed changes rapidly, suddenly adjust from the high speed to the low speed, the flameout occurs, please confirm whether the throttle is closed less than 1.5mm, or gradually reduce
RS-S100x series is a very precise machine that you need to clean timely. Due to the impact of
environment and the fuel when using, the engine parts have a certain amount of wear and corrosion. So, TOYAN will also provide you with long-term maintenance services. You can also complete the
basic cleaning and maintenance
●Carefully clean the carburetor and remove dirt and grease from the inlet
●If an air filter is used, make sure the filter is clean and free from blockage
●Recommended that the air core used for more than one hour should be replaced in time.Be careful to remove contaminated filter elements to ensure that dirt does not enter thecarburetor.
● Do not remove timing synchronous belt, you can use alcohol as a cleaning agent to wipe the belt.
Do not use corrosive detergent to clean synchronous belt, to avoid damage
●Glow Plug must be treated as consumables. Long running glow plug will not ensure the normal
operation of the engine and you can extend its life maintain the performance of the engine if you
 use it carefully
◆Use appropriate tools for disassembly;
the auxiliary oil needle, (clockwise rotation) gradually adjust the auxiliary oil needle, 20°as units, until the engine maintains a steady idle speed. In the debugging process, the auxiliary oil needle should not be excessively reduced, so as not to cause engine have lean oil, we recommend that the minimum value of auxiliary oil needle should not be less than 1 turn.
◆Use fuels containing a moderate percentage of nitromethane;
◆Do not overtilt the engine and do not connect the battery while adjusting;
●The time to replace the glow plug. expect burned, It also need to be replaced on these situations because it no longer provides optimal performance,For example:
a.The surface of the filament becomes rough and white
b.Filament curl deformation
c.External material adhered to the filament or plug corrosion
d.The engine will power off when idling
e.The power went out after the engine started
●At the end of each operation, empty the fuel tank, energize the glow plug, and try to restart the engine to burn the possible left fuel in the fuel tank. Repeat this process until the fuel is cleared from the engine.
●Inject some antiseptic oil and briefly start the motor to distribute the oil to the working,parts.
Do not inject this oil into the lubricator nozzles, as this may cause the O ring of the carburetor to
●Add solid lubricant to camshaft and valve tappet to ensure that the CAM axle box has enough l
ubricant for each operation
These maintenance programs will be stored after a period of time, and there is a risk ofcorrosion
 or startup difficulties, if you need someone to deal with, please contact us
After long-term operation, the friction between the engine components will cause wear and too
large gap, the replacement of related parts will help you maintain your engine better. When
you are in the process of use, there is not flexible start, power reduction, idle speed instability
and so on, please feedback your usage process and poor performance of the engine to the local
 dealer or TOYAN, we will serve you wholeheartedly. Parts replacement, we will provide
professional equipment and experienced team. Please do not disassemble the engine without
professional tools to avoid the risk of uncontrollable damage to the engine.
If the engine fails to start, check the following carefully:
●Whether the battery voltage is normal, whether the power is full
●Whether the glow plug has failed
●Whether the fuel can reach the carburetor smoothly
●Do not start the engine when it is flooded. Remove the glow plug, close the oil needle and
press the start button to drain the excess fuel. (Cover the plug hole with a piece of woolen
cloth so that the fuel doesn't spill on you.) If forced to start without removing the excess fuel, it
may cause irreversible damage to the starting system, as well as the connecting rod and
crankshaft to strain and deformation
●Timing belt adjustment
All TOYAN engines have been tested for timing belt position before they leave the factory.After
several hours of execution, the operating power loss or engine running instability is found, the
timing belt needs to be tested and adjusted to get the correct ignition information for the engine.
 Please check against page 11 of "timing belt timing diagram"
●When Turn off at low speed, do not keep it at too low speed a long time. Since the methanol
engine needs to maintain the temperature of the spark plug filament to achieve ignition,when the engine is in a rich state for a long time at a low speed, the temperature of the filament will
gradually decrease, resulting shutdown. Therefore, it is necessary wait a while to up the speed oil
and clean the oil to keep the temperature of the filament


 Other Questions People Might Ask

1. I received my RS-S100 Single rotary engine but it is missing the Cooling fin it. Can you please package the fins with this one when it is dispatched?  On another note, there is no starting procedure or instructions in the box only basic information. I need to know what glow plug to run in it and what percentage of nitro fuel to run.

Since it is water-cooled, the radiator has been canceled. At present, the single-rotor engine does not include the heat sink. We will share the latest news about the heat sink in the future with you and improve the basic parameters of the product, start-up method, accessories use, and other information in the near future. Fuel uses 20-25% nitro fuel. Glow plug uses OS four-stroke F-type glow plug.

2. I have received the single rotor rotary Toyan engine,
a. Is there a better manual for this engine? The one that came with the engine is useless.
b. Is there a different flywheel for this, one with a V-groove for belt starting?
c. What direction does the engine run?
d. There are 3 fluid connection nipples, are all 3 for cooling?

We will improve the basic parameters of the product, start-up method, accessories use, and other information in the near future, and send a detailed instruction manual to you by email. It has only one flywheel. While the center of the rotor revolves around the center of the output shaft, the triangular rotor itself rotates around its center. The top of the three connecting nozzles is for oil intake, and the other two are responsible for intake and exhaust.

3. I received an RS-L200, but when I turn it manually clockwise, it locks and stops. There are metal burrs on the case, disassembled and scraped off the burrs, but I also found a problem with the apex seal. Can I get Vertex Seal's warranty?

Hello, please send me a photo to check. after it's confirmed, i will resend you a  engine apex seal.


I have a question. Had to disassemble my spinner because it wouldn't turn properly and it still wouldn't turn properly after removing it. I disassembled and assembled it 4 to 8 times. Now it just gets stuck sometimes. By the way, I can't find where the card is. But my feeling is that the gears cut sharply. Seeing as I've reassembled 10 times I don't think this will help. My only question at the moment is how to get my engine running and why does it keep getting stuck. I took it apart and the one without the apex seal still remained jammed. The shaft is not stuck. The front rotor is installed and it turns fine. The rear weight seems to be the problem. I can't get it to turn. Every disconnect gets worse. Now it's completely stuck. Just tried to start it and it got stuck again. The engine never runs. Here you can see it. It's free and then completely stuck. I hate to say that, but I need a complete engine replacement. It can run at least 6000 rpm. Please use the aircraft starter. I've done that but it won't turn, it's stuck. I have started the 10 cc diesel engine with the starter you see in the video. My 20 cc twin is too big for it. But seeing as I have rebuilt a bunch of bigger rotary engines. How else do you think I can build my own full-size spinner. There is also a spinning RC car with a recoil modification.

5. is it easier to start the rotary engine with the base? what next plan do you have for this rotary engine? and can you pls do me a favor to write some practical tips for the Toyan rotary engines? because we still have many people who can't get it run.

The base makes it easier, yes, still pretty hard to start. The engine requires a lot of fuel and does not idle very well. I think it will not last long as you need to rev it very high in order for it not to stall. It would be very frustrating to install it and then have it blow up or keep stalling every second.

To start the engine it is always important to have a fully charged lipo battery. I use a 3s lipo with over 4000mah. The bigger the better as the battery needs to power both glow ignitors and the starter motor. Also, the 3s battery is necessary as it will spin the eclectic motor faster which is important. Check that you have a good ground connection on the engine otherwise the glow plugs will not ignite.

This engine runs very hot and needs to be water-cooled. You need a water pump to circulate the water throughout the engine. If you do not run water cooling there is a big chance that you could potentially seize and ruin the engine.

The rotary needs plenty of fuel to start, much more than a traditional 2 or 4-cylinder engine. I use 25% nitro, this is what is recommended. An important and easily overlooked step is to make sure that the fuel is not old. Sometimes this can have an effect and potentially not being able to start the engine.

To start, prime the engine by placing your finger over the carb and spin over the engine to push fuel through the carb.

Once it is primed and all the above steps are completed spin the engine over with the throttle approx halfway open, You might hear it sputter and try to start, if so then while the starter motor is engaged put your finger over the carb to push more fuel through. It will take several attempts to start.

Once it starts keep the throttle mid-way open to keep it running and get the temperatures up. Once warm it will be easier to start and then tune.

7. Can You Please show me how to connect the Toyan rotary Engine?

 yes. you can check the photo below.


8. I like the water pump of the Electric Start Kit Starter Motor, can I use it?

There is some little change in design and difference between the first batch and the second batch depending on the feedback of the first batch engines. The second batch orders were shipped in October. The Electric Start Kit Starter Motor is more suitable for the second batch engines. If you bought the first batch engines,you can use the original water nozzle without adding a water pump.


9. Reminder for the 2 Rotor Rotary Engine Model Watercooling with Starter Kit Base Full Set

You need to pay attention that the water tank should be installed to the two screw holes outside when you set the engine base. This length is not enough, and it will withstand the water tank.
