It was bought direct from a shop here in spain by me.
It has only about 4-5 months usage.

Why should I change the glow driver after run-in?

Today, the other man looking at my engine has been a world champion acrobatics pilot one year and a spanish champion many other years.... he is apparently known as "mr motors"
He was starting to get confused as he would find one problem "fix it" and another would appear... Unfortunatelly he had to leave before finnishing.


The assembly at the rear hasnt been removed because I couldnt be bothered removing it as it makes no difference to the plane it being there.........


Truthfully i'm starting to think... "oooooosssssssss! ooooooooossssssssssssssssssssss! oooooooooooooooooooooooooossssssssssssssssssssssss sssss!" (long drawn out haunting, dream style sound) Mostly because its more common, its more reliable and the other guys at the club all have them, IE they can help me out more as they "know" the engines better.
plus moving from something that was €50 to €150, where the money is worth it, isnt a bad idea to me!
