Hello all - I'm new to the forum - I hope some kind person can help with a question of calculating scale weight in a scale model of a glider.
I want to test the glide ratio of a glider design by making a 1:4 scale model and thowing it from a certain height at a certain speed and measuring how far the model glides.
Suppose the design has 10m wingspan and the model has 2.5m ws.
The question is: if the full scale design weighs, say, 100kg (including pilot) what should the 1:4 scale model weigh?
(And, I'm supposing that the scale speed should just be reduced to 1/4 ?)
