this was one excellent glow plug I ran about 1/2 a gallon of 20pcnt nitro still running strongPlace this plug in a ST 51 airplane engine installed in a DC F 20 Tiger Shark that I had not run in over 5 years. The engine started the first spin of the starter. The engine blew out the excess oil, the transitions from idle to full throttle was solid ... the idles were solid, I experienced no dead sticks, with this plug.
TrackStar 1/10~1/8 Scale Glow Plug No.5 (MEDIUM
is very bestNice quality glow plug, cheaper than other brands but just as good. Seems very similar to the Hobbyking variant, but the Trackstar ones seems to run a little hotter than Hobbyking's despite the same rating. Need to richen up after replacing the Hobbyking (medium) plug with this Trackstar plug.buena y fantstica a buen precio
