Ok, well when i brought my Hyper 7 the other day, i also brought with it a nitro starter kit containing the usual begginers bits n pieces, as well as a spare glow plug!

The glow plug is an O'donnell 102 Medium, recommended for engines .12-.18

Obviously, my engine is a .21, so i called ModelSport and asked if it was ok to change it for the equivilant plug for a .21 engine - which I believe is the 100 for .21-.50 engines.

They said ok fine, but they also said it should run fine on the 102 plug.... is this true?? Will it run ok? They market the two plugs for different engine sizes (for a genuine reason I assume!), so what actually is the difference?

Many thanks!

Just run it on the plug you have, it will not make a difference and you should change the plug once the break-in is completed anyway. Chances are that the plug dies during break-in too. You need more than one plug, so just get some spares immediately
