'Glow Plug Thread' System

Glow plug thread (1/4" x 32) ignitions

We are the main supplier of these excellent miniature spark plugs and CDI ignition units for converting glow engines and as replacements for OS, Evolution and Saito Engines. The spark plugs have a 1/4 x 32 thread to match the standard RC glow plug thread. The CDI units are robust and reliable with an input voltage on the newest one up to 12 volts. They also now are available for singles, twins and V twins as well as five seven and nine cylinder radial engines.

Our customers have converted engines as small as 2.5cc with great success.

Read customer experiences on converting their engines here and please let us know your experiences as we are aiming to build a really useful resource for the benefit of everyone.

CDI Installation

CDI Installation

Installation will vary depending on the type of engine being converted to use CDI.

Download a PDF file of the instructions here: ignitioninstructions.pdf

When converting an existing electric ignition petrol engine to use this CDI unit the required magnet should already be mounted on the engine. When converting a non electric ignition petrol engine, or a glow engine a magnet will need to be purchased (see below) and fitted.

When converting glow engines to run on petrol the compression ratio often needs to be reduced, this can be done by fitting extra head shims to the engine. These can be purchased for all the engines we sell here - Engine spares.

After a long wait we can now offer a solution to those who want to convert their radial engines to spark ignition. RCexl have spent a long time refining these units and tuning the software to give a great and reliable system. Powered from 6 - 9.4 volt supply and designed to work with our glow sized spark plugs and supplied with a special hall effect sensor. All have 120 degree caps to fit glow plug sized (1/4") spark plug as standard.

The timing is achieved by fitting a magnet for each cylinder and one inverted to prime the system. The set up is very important and will involve some engineering skill. However if you are not up for this please ask about our pretimed prop drivers and sensor brackets.

Please select number of cylinders above, prices are as follows and shown in brackets above:
3 cylinder 124.56
5 cylinder 224.00
7 cylinder 261.34

Ignition Test Kit

Ignition Test Kit


Price: 8.16 (Including VAT at 20%)

Quantity:

The Ignition test kit is a very useful tool for testing the both the operation of the CDI unit and for interference with electronics in the aircraft. In use the unit takes the place of the sensor and can supply a pulse that mimics it over a range of 400 RPM-20,000 RPM . The unit has a thumb wheel which allows the user to select the rev range required when testing.

When connecting the unit it is important to have the white wire (pulse out ) marker on the circuit board. It allows the user to range check the aircraft without the need to run the engine.

Opto Petrol Engine Kill Switch

Opto Petrol Engine Kill Switch


Price: 15.31 (Including VAT at 20%)

Quantity:












This is a must have for petrol engine users, the engine can be switched off via this unit which remotely kills the electronic ignition from a spare servo channel.

The unit is 'opto' isolated to give interference free operation, totally isolating the CDI from the electronics of the unit receiver.

The unit incorporates a very bright LED to indicate when the ignition is armed.

The unit is managed by a PIC micro controller, giving it a fast response time and it only weighs 0.3oz (8g).

This device allows you to kill the engine at the flick of a switch on your transmitter and therefore, by using the failsafe facility on your radio system (or a standalone failsafe unit), it could be configured so that the engine stops if the radio signal (or receiver battery power) is lost.

Onboard Mini tachometer

Onboard Mini tachometer


Price: 15.31 (Including VAT at 20%)

Quantity:

The mini onboard tachometer uses the pulse from the HALL sensor to give a bright display of the engine's R.P.M. x 10.


The supply for the unit is taken from the Ignition battery so no extra battery is required, but it can also be supplied direct with a voltage range 3.5v to 8.4v at a current of 25mA and a rev range up to 30,000rpm.

The window size 41mm x 17mm x 12mm makes it a very compact unit.

A "y" lead is supplied with the tacho to connect it with the sensor and the C.D.I.
