What is the Max Height Allowed in Your Country?

[UpLift Aerial]

Here in Canada it is 300' / 90M. could be more, like 400' / 120M like most countries.

Here in Belgium it is 10m if the AC is under 1kg and only in your private property or in a designated model aircraft zone as part of a club's activities, under the 1kg then it is classed as a toy and does not need a licence.
Aircraft over 1kg and under 5kg, then you need a Class 1 licence and you are limited to 45m in height, you are also restricted in how close you can come to persons and/or property and you cannot fly closer than 1.5km from an airfield.
There are other regulations but that's the headlines figures.

I'm about 3.5km from a very active airfield and we have fast movers at less than 500ft still in afterburner passing over the house almost every day, so even 10m seems a bit high from my point of view on the ground when you can make eye contact with the pilots passing overhead

Actually most countries do not have such limits. Several do but not most.
