Just been reading up on to demolition springer, I'm a bit disappointed with the lack of support, so far I can make out five people who would take part, the four of us from Scotland and big bad ian, big bri came up with some simple rules. Made out of balsa, standard size which I believe there is plans on this site, no power tools, weapons have to be made, all the rest is up to the builder, surly by the the name, people would get the idea they are taking the risk of there boat sinking, if your worried about cost don't take part, event can be done at the end of the day, I'll join ian in the pond cleaning up and I'm sure others would as well, I'm with big bri if it's watered down from the original plan I'm out, people who won't even be at the event really shouldn't have a say, it's for the people who are going to attend.
