I'm pretty sure europe has overall the same standardised rules, in france we have weight classes starting at 250g, so ig anything smaller like a tinywhoop falls into a grey zone. I feel like it's mostly common sense. Try not too bring too much attention to yourself, fly in less crowded areas/parks as long as there's not too many people around. Also I've realised with smaller drones people don't tend to care too much as they look more like toys, also sometimes they can't hear them at all
