The power to fly is effected by a number of factors and probably the most important is aerodynamic efficiency of the air frame in converting thrust into lift.
The next issue is the speed is has to fly at to generate the required lift. The speed required is proportional to the wing loading.
So 'smaller' at a given weight will require more power to fly (it has to fly faster) than 'bigger' at the same weight.
To answer you question about the power to fly a 500 g weight plane you do need the shape and size (area) of the wing.
A delta is not particularly efficient shape so if you can get your 500 g plane to have a wing area of close to 0.4 sq m it should be able to fly quite nicely with 100 W and have quite an aerobatic performance with 150 W.

That'll fly .

A couple of tips :

1) For slower docile flight , make the airframe as large as possible . A small airframe may be hard to handle for an inexperienced RC airplane flyer .

2) Make the prop slot only as big as it needs to be for the prop . A giant prop slot hole takes away wing area , and will also weaken the airframe ( more likely to break if it hits the ground nose-first ) .

yes it seems like it will fly, can i fly it? that's a different question

it's very interesting how you can use hot glue for the hinges
