Thunderbolt Glow Plug - R/C Long Thunderbolt Glow Plug - R/C Long Thunderbolt
When Thunderbolt first started producing glow plugs in 1972, we needed a plug that would make up for the inefficiencies of most airplane carburetors at the time. The R/C Long did the trick.
The "idle bar (or "RC" type) physically protects the coil from carburetors that run rich at the low and mid-ranges. Have an airplane engine that just doesn't seem to want to idle and transition? This is the plug.
For over 25 years, this was by far the most popular plug we had ever made and with over a million sold, it continues to be the goto plug for many modelers.
