Weight Twin: less battery - 6.1oz

Plug size - 10MM NGK (CM-6)

Warranty - 2 year

2.) Selecting a Power Source

I.) 4.8 and 6v volt NiCd/NiMh Packs:

The Rcexl Ignition ver 2.0 is rated 4.8 to

6v a max of 7 volts. A 4 cell 4.8v pack and

5 cell 6v pack with a minimum of 800

mAh is fine and creates a hot spark. The

Rcexl ignition ver 2.0 runs most efficiently

on 4 cell packs and 5 cell 6v pack . Do not

use an old Pack!! If it’s not good enough

for your receiver, it’s not good enough for

your ignition..

If Use 4.8v pack the engines not highest

rotational speed, Also use 6V pack

II) 6.4 Volt Li-Fe(A123) Packs

2cell Li-Fe(A123) The Volts Max of 7.2

volts. Nominal 6.6 Volts, use a voltage

regulator. Or connects one IN4007 diode

to fall voltage the use.

If engines not highest rotational speed,

Also may directly use

III.) 7.4+ Volt Li-Poly Packs.:

We have found that 2cell Li-Poly Packs at

peak charge can be as high as 8 +v. If you

are going to use a 2 cell Li-Poly Packs,

you must use a voltage regulator. Or

Serially connects two IN4007 diode to fall

voltage the use The Rcexl ignition runs

more efficiently on about 4.8-6Volts and

will draw more current at around 8+v, as

well as operate at a higher temperature.

You also have a higher chance of RFI

interference.

In brief in can satisfy under the engine

highest rotational speed touse the quite low

voltage as far as possible

Once again, do not use an old pack to

power your ignition!

3.) Installation

I.) Spiral Wrapping:

Use the supplied Spiral Wrapping included

with your Ignition to protect the wires from

heat and chafing. Wrap the braded Spark

Plug Lead, Hall Sensor Harnesses and

Battery Harnesses.

II.) Mounting:

Mount your Ignition on the engine box if

possible. Wrap the ignition in foam to

reduce the effects of engine vibration on

the circuitry like you would do with your

receiver. You can use the mounting tabs

on the ignition but we recommend using

zip ties or Velcro ties to secure it. Do not

install your ignition in the fuselage. Keep

the ignition as far away from you receiver

as possible and never use the same power

source to run your ignition and receiver

jointly.

III.) Connecting the Battery:

The Rcexl ignition utilizes the Futaba style

plug ends and comes with an additional

pigtail to add to your ignition switch if

necessary. Be sure to follow the color

coding (Red +, Black -) when attaching

you’re your power source and on / off

switch to your ignition power leads (see

fig.1). Wrap you battery with foam and

mount it as far away from the receiver as possible, preferably on the motor box. fig 1. If you are going to attempt to use your existing hall sensor, see (fig. 4) for the wire orientation. (Red +, Black –, white signal) Fig. 4 IV.) Turn the crankshaft clockwise (opposite to the engine rotation) until the wheel reads 28 degrees. Connect the Battery to the ignition insuring that the Spark Plug is not in the cylinder.
PAGE 3
Insure that the voltage is 6v or less to the ignition. II.) Connections: Check that all connections are correct from the battery, to the switch, to the ignition. Use a volt meter on the switch to ensure the ignition is getting power and the polarity is correct. III.) Hall Effects Sensor: Ensure that the orientation of the hall sensor is correct with the orientation of your hub magnet. If you used your existing hall sensor, make sure that the wire orientation (fig. 4) is correct. 5.) Safety Precautions.
