RE: Radio interference/ power
Didier,
Get in contact with the distributor and ask for a copy of CE paperwork. I am assuming that the kit is CE marked and tested to the latest EN Type Approval and EMC Directives.
Do they allow kettles / toasters / radios in the workplace ? If so, then they too should be Type Tested and EMC tested. If that is the case, then there is no reason why they wont allow you to use your R/C gear
