The following information is provided more fully in the Advanced Glowswitch Handbook

The Start-up Boost switch is particularly useful for those engines that need a bit extra when starting. It ensures full glow power for starting but retains the normal trimpot setting for in-flight support.

All AGSs are fitted with a connection for the Hidden Helper start-up boost. The Hidden Helper boost switch consists of a magnetically operated reed switch with a 500mm lead that plugs straight into any AGS or IG- b. Scale modellers will appreciate that the switch-head can be fitted wherever is convenient and out-of-sight in the fuselage or cowling so that a magnet [in a finger ring or glove for example] will operate the switch when the model is held for starting. We also supply a suitable high strength operating magnet if required.

NB: You can replace the magnetic reed switch with any conventional switch of your choice.

See the Advanced Glowswitch Handbook for instructions on making a suitable magnet ring.

Helping Hand Boost Switch Part No HH-SB

Helping Hand Operating Magnet Part No HH-DM

Aero-HT Heat Resisting Cable
Typically the resistance of a glow plug is about 0.3Ω and it is all too easy to build up a similar resistance in the wiring. Even if the wiring resistance adds up to a modest 0.15Ω the plug will only see 2/3 of battery voltage. Aero-HT silicone rubber insulated ultra-flexible cable has a minimal resistance of a mere 0.02Ω per metre. Supplied in 500mm lengths each of black and red they are suitable for extending wiring cable lengths.

Part No HT-5

Cent-r-Lok Connectors

The Cent-r-Lok connectors fit OS and YS glow plugs. Supplied as a set of parts, once assembled, they can be fitted and removed without the use of tools.

Cent-r-Lok Engine Connector Pair

Supplied with 500mm Aero HT cables. Suitable for connecting to a single cylinder engine. Two of these should be used if connecting to two separate engines.

Part No CL-1

Cent-r-Lok Twin Cylinder Connector Triplet
As above but with two glow plug connectors each with 500mm HT-5 cables.
Suitable for connecting to a twin cylinder engine.

Part No CL-2

Heavy Duty Slide Switch

This heavy duty slide switch can handle 12 A per side (24A with both sides wired together). Used with our other wiring accessories will ensure that the maximum possible power reaches the plug.

Part No SS-HC

Ferrite Ring Cores (Pack of Five)

In the very rare cases of models where the signal to noise ratio or aerial tuning is compromised (by an all aluminium skin for example) these cores can help to limit the importation of noise into the Rx. Cables suspected of carrying interference can be looped through these cores to form noise reduction chokes which won't affect wanted signals. These toroids are large enough to feed a servo cable through up to five turns (the more the better) without removing the plug. See the Advanced Handbook for more information.

Part No FC-GM

Battery charging

On-board NMH, NiCd and Cyclon battery types may be charged in-situ using your existing charger, our separate charger connector CH-OC can be used to provide connection to the CH-IG on-board Charging connector. Be sure to read the notes in section 7 of the Advanced Glowswitch Handbook. NB. It is not advisable to charge Li-Po cells while they are inside a model.

On-board Connection for Battery Charger
Provides a charger connection for the on-board battery.

The 300 mm cable can be shortened to suit the installation. The white traced wire should be connected to positive.

Part No CH-IG

Separate Charger Connector
Mates with CH-IG on-board battery connection for connecting your charger.

Comes with 500 mm cable. The white traced wire should be connected to positive.

Part No CH-OC
