Alligator Pigtail is easiest to install
on/off your glow plug, and does hold on to the glow plug better then you'd
think. It is a great solution for glow plugs sunk deep into the engine. Best
choice for Helicopters and larger Cars, Trucks, and Boats.
Clip Pigtail was traditionally reserved for
the Airplanes due to its horizontal connection to a shallow or exposed glow
plug, and works well to avoid a nearby cowling. However, we found it can also be
effective on exposed Truggy engines as it will lace between the fins of .28
engine to avoid breakage from a rollover (as shown below). Best choice for
Airplanes, and larger exposed engine Truggys
Twist-Lock Pigtail has been around for 40+
years. It's ideal for shallow and exposed glow plugs. It produces a secure
connection and a great look on all crafts especially scale Airplanes. Another
bonus is we have terminated the ground wire on the shell, so no need to install
a ground connection to your motor or backplate. Best choice for Airplanes,
and smaller engine Cars, Trucks, and Boats. Will require long nose pliers to
install on deeply sunk glow plugs.
