Hi there, I havnt been here for a while but ive recently got a hyper 7 sport (and i know many people here dont recommend the sport so please dont start saying i shouldnt have got it lol)

Anyway, it has the hyper 7 4-port pullstart engine, but it didnt come with a glowplug (not sure if it was meant to or not), so what would be a good glow plug to use with this engine?

Thanks
