Mathmos Revolution

[C*O*O*L*S*O*X]

I know it's not Lava, but does anyone else here have the Mathmos Revolution? After around 10 minutes mine stops rotating. I may occasionally have the odd burst but generally it just sits there motionless. Anyone else experiencing the same problem and is there a fix?

The one had I had to adjust the top heat fins . If they are not exact/balanced as the heated air rises the hotter it is the better the prop fins turn however as the candel burns the heat becomes less and the blades stop working well. If the balance is off and is not sitting just right it will run fine in the beginning and then as the heat begins to drop it will stop. The one I had the balance was off and I had to form the fins to have that perfect match.

I have a few of the revolutions Richard and they don't seem to do that. Check the top pole bit with the white thingie isn't worn out. That is the only thing I could think of.
