• Always perform a range check prior to flight. • Always use the throttle linkage to shut off the air or turn off the engine power switch to stop the engine. • Never use hands, fingers, or any other body part to stop the propeller. • Never throw any object into a propeller to stop it. • Never run the engine in the vicinity of loose small objects, such as gravel or sand, to avoid the propeller uncontrollably throwing such materials.
Introduction Thank you for purchasing the exciting new Evolution® 62 GXI engine. A first in gasoline RC engines, the 62 GXI features a throttle body fuel injection system. No longer will you have to deal with needle valve settings and tuning your engine. The 62 GXI automatically manages fuel metering, letting you worry about more important things like flying! Mounting the 62 GXI is simple with the overall dimensions designed to fit current giant-scale offerings.

Installing the Muffler 1. Put a lock washer on each of the muffler screws. Push the muffler screws through the muffler. The muffler mounting accessory package includes mounting screws (2), lock washers 2. Place the muffler gasket over the muffler (2), muffler gaskets (2) and an L-wrench. mounting screws. We suggest using high-temperature RTV as a 3. Align the muffler gasket with the exhaust locking agent on the muffler screws to keep opening and the muffler mounting screws. them tight. 4.
Throttle Curve Setup The engine’s throttle body flapper valve provides 1. Ensure you have set up the throttle linkage non-linear engine response to throttle changes as described in the Connecting the Throttle (greater power increase between low throttle to Linkage section. It is very important that the 50% than 50% to full throttle).
Attaching the Propeller and Spinner 3. Begin to tighten all 4 screws until they are all hand-tight. 4. Tighten all screws with the included 4mm L-wrench in a clockwise circle until all screws are tight. 5. Install the spinner cone. Make sure the spinner cone is not touching the propeller. Trim the propeller opening if necessary. 6. Tighten the spinner screw to secure the spinner cone.
Connecting the System Wiring Harness Assembly The battery voltage required is 8.4V (2S Li-Po battery). Do not use a voltage regulator. We recommend a 2S Li-Po battery (such as the Spektrum Li-Po Receiver Pack 2000mAh (SPMB2000LP)) as we have done extensive testing with this pack. The maximum current draw at full throttle is 650mA, and our more typical average has been between 300–350mA.
Fuel This engine requires a mix of 32:1 gas to oil lubricant ratio for break-in and a mix of 40:1 gas/oil ratio for normal operation in order to last a long time. The needle bearing at the bottom end of the conrod depends upon this lube ratio to operate properly. Do not go leaner than a 32:1 gas/oil ratio for the first gallon of fuel. After this you may decrease the oil content to a 40:1 gas/oil ratio if desired. Do not go leaner than a 40:1 gas/ oil ratio or the warranty on your engine will be voided.
Engine Fuel Injection System in Operation The 62 GXI features an adaptive algorithm that will “learn” the best settings for your environment and flying conditions every time you run the engine. When the engine is shipped from the factory, it is loaded with base settings that will enable you to run the engine in any environment. As the engine runs, the adaptive algorithm fine-tunes the settings for your environment. Every time you power off the EFI, it resets back to the default settings.
Telemetry Telemetry is a huge asset to help you take care of your engine. The EFI/ignition module is even capable of communicating with Spektrum telemetry systems directly so you won’t have to add an additional RPM sensor. You will need to connect the Evolution Ignition Telemetry Adapter (EVOA107) between the “Telemetry” connector on the EFI wiring harness and the RPM port on your Spektrum telemetry module in order to utilize this feature.
Troubleshooting Guide If the Engine Does Not Start • Check and use a new spark plug if needed. Check by removing the spark plug from the cylinder. Remove the spark plug and resinstall it into the ignition plug cap. With the engine power system ON, move the sensor magnet past the sensor quickly (by flipping prop or manually moving the sensor past the magnet). You should be able to either see or hear the clicking of the spark plug firing.
