Welcome, and great to hear you have your first robot built!

As Gary said, we do have a space or two spare at Gadget Show Live for the UK Championships - so if you do want to enter just get intouch Via e-mail or PM on here (or even just post on here and we will get intouch).

The UK championships would certainly be the best for putting your robot to the test and learning how other's do things and getting the most from your robot. However, as said above there's a good chance of receiving some damage.
We do have spaces available for Fleet Air Arms museum event, which is a great relaxed event but has the full combat arena for spinners. You don't need to fight any if you don't want but its a good time for testing and making mods in a non stressfull event!

Good luck
