ORIGINAL: Primodus
Application: Saito 120, inverted, VF Edge 540. In the inverted position the glow plug points down and back, making it difficult to get to when the motor is concealed in the cowl and dangerous to unplug when the motor is running. I have since been able to adjust the motor for more consistant starts, although I am still running it rich at this time (4th tank, 14oz). The use of an onboard glow is an effort to maximize safety and ease of starting, as well as, increase engine reliability in flight.
Application: OS FS70, inverted, completely cowled in, switch on side of fuselage to a single 2400mah nicad. Switch on for starting and left on for entire flight. Good for three 6 min flights.
Beautiful reliable idle, never had a plug failure (used over a year with F type plug). Glow plugs draw 3 to 4 amps, so 2400mah should keep plug lit continuously for 36 to 48 minutes. Use 20 guage or heavier wire.
