A330,
The best place to go for advice on Vans in the UK is the
UK RV Yahoo group. You'll need to register to read it.
There aren't any RV-10s flying in the UK yet, although there are some under contruction in the UK. However, the design doesn't have full PFA approval yet (but is going through the process), so importing one from the US isn't an option, and has an element of risk anyway - see
this PFA document
It is a very nice aircraft, as are all the Vans designs
