Flight Glow II The FLIGHT GLOW II is an advanced glow driver for model aircraft engines, both single and multi-engine operation. The FLIGHT GLOW II requires no adjustments, just plug and glow. The internal computer determines the idle setting, even if the channel has been reversed. At idle or start the glow plug is on 100%, as the throttle is advanced the power to the plug is reduced until it is off at about 1/4 throttle. You can see this by the amount of time the indicator is RED. The tri-color indicator also shows the condition of the battery or batteries for twin operation. An optional remote indicator is available. For installation, operation and charging instructions click HERE
