Thanks all for the replies.

I think I will give Lifers suggestion a go, was thinking along the same theme myself, thought I would go to a local golf shop and see if they had any old stepped club shafts that I could use instead of copper tube.

Yes I too like the sound of real engines but you've got to admit the DLE20 is a little over the top, its not me thats bothered just a little concerned about others that live near our flying site.

I have seen the exhaust plugs that are on offer from Valley View, but anything I've imported from the States recently has been hit with very high import duty, value added tax, and handling charges for the privalage of paying the duty/tax, whilst when buying from China it sails through at no additional cost, very strange!.

Cheers

John
