My son has a few radio controlled cars that we brought over from the UK when we moved. Hopefully we will get our stuff out of storage in a couple of weeks and he can use them again.

Does he need a permit to use a radio controlled toy or model in Switzerland?

What frequencies do the Swiss use for radio controlled models?

Is it OK to use radio gear from the UK or US?

do they operate at 433Mhz?

He has some that use 27Mhz, others that use 40Mhz.

I found this http://www.ukrcc.org/switzerland.html just a few minutes ago which I will use to cross check his crystals with.

I still don't know if a permit is required, I am assuming public liability insurance will be required and I will check with our existing insurer if it is already covered.

There is no license required.

Liability insurance is required by clubs (and is also a very good idea even if you fly out of a field) for planes and helos and it's a plain vanilla add-on to the normal insurance.

There's little chance of this happening...
