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. Telemetry

systems other than Spektrum may require a

dedicated RPM sensor.

We recommend using the Spektrum DSMX Full

Range Aircraft Telemetry Module (SPM9548)

in conjunction with the included adapter. This

system allows you to see real-time RPM and

temperature readings from the engine.

The temperature sensor should be wrapped

around the base of the spark plug on the

cylinder head with the thermistor facing

towards the front of the engine. Using

telemetry gives you an accurate representation

of actual temperature and rpm ﬁgures during

use, and warnings can be set to go off if your

engine is getting too hot.

The temperature range should be 190–240°F

(87–115°C) on average. Set your maximum

temperature warning to go off if the engine

exceeds 270°F (132°C). If your engine is

continually near this peak temperature or

higher, immediately decrease throttle to bring

the temperature down.

If this continues to occur, land the airplane

and investigate getting more effective cooling

to the engine. Often this is accomplished

by adding bafﬂing that directs the intake

air more directly over the engine. Or you

can increase the hot air exhaust area from

the cowl. It is not good for the engine to run

at temperatures this high and could cause

damage if not attended to.

Telemetry

It is critical to the proper operation of your 62

GXI that you use the included ﬁltered clunk.

Fuel should also be ﬁltered in your fueling

system before it enters your model. Failure to

properly ﬁlter the fuel before it reaches your

engine will have a negative impact on the

engine’s performance and reliability.

1. Power ON the radio system but leave the

engine power system OFF.

2. On the ﬁrst ﬂight of the day, press the primer

bulb 10 times. There is no need to worry

about ﬂooding the engine. If the primer bulb

is pressed too many times, it will only return

the extra fuel to the fuel tank.

3. Move the throttle trim to the center position

and keep the throttle stick at idle.

4. Power ON the engine power system.

5. Rotate the propeller counterclockwise until

it is against compression. Flip the propeller

through compression until it starts.

6. Let the engine run at high idle for 30

seconds to stabilize the temperatures.

7. Lower the throttle trim to your desired idle

setting.

If the engine doesn’t start quickly

1. Check to make sure fuel is moving through

the EFI by pressing the primer bulb and

watching the fuel lines.

2. If the engine appears not to have any fuel,

repeat the priming procedure in step 2.

Repeat 1–4 of Starting and Running the Engine.
