I'll bet your plane is very nice. I hope you will post a picture of it soon!

Here in the US, our irons just have little numbers on them. I don't know how that converts to balls or degrees centrigrade for that matter. I find a monocote iron more convienient and usually set the heat a little past half way.

My parents must have know I would build toy planes since they got me three brothers. I can't wait to hear about your first flight!
