Thunderbolt Four Stroke Glow Plug – Optimized for 4S and Big Bore Engines Bin 217


Out of stock


Mike Goes Flying is proud to re-introduce Thunderbolt Glow Plugs! A mainstay in the modeling community since the earliest days of Hobby Shack, Thunderbolt glow plugs use the highest quality proprietary alloys in a plug constructed with a patented stem-seal to maximize performance, reliability, and consistency in modern glow aircraft engines.

The four stroke plug was developed using the latest technology from metalurgy to coil and bore diameters. This study lead to the highest performance four stroke plug we’ve ever used. Idle is as good or better than all competing four stroke plugs, and generally the performance numbers on the top-end improve by as much as 500 rpm. In the end we don’t have to hide the wire to keep the plug lit at low rpm and at high rpm, the coil is where it should be, thus giving better burn on every ignition stroke.

Because the plug hold heat so well at low rpm, it makes for a great plug is the very larg bore two strokes like Moki and Super Tigre.

Thunderbolt: Dependable since 1972

Thunderbolt Application and Heat Range Reference

R/C Long = Cold (great for Sport RC Aircraft engines and also used in some control line applications due to the idle bar)

Platinum No3 = Medium (Made specifically for aerobatic aircraft with 2 stroke engines that need improved mid-range perfromance)

Four Stroke = Medium (Made specifically for the conditions of 4 stroke engines where they fire every other stroke, which also means they work great in larger bore two and four stroke glow engines that are idling slowly, for example MOKI/Mark engines and the Larger Super Tigre engines)

Standard Long = Hot (Some control line engines and other two stroke engines such as KNB tend to do best on this plug)
