Quadcopter becomes unstable at scales of <=40%

Hi, I've tried scaling the default quadcopter down and noticed that it becomes unstable at <=40% (i.e exploding).
May I know is this due to a threshold on the minimum size required of the components, or is it caused by something else?
Thanks in advance!

Hello,
you will have to adjust the quadcopter controller code if you scale the quadcopter.
Cheers

Hi Coppella, thanks for the advice.
In general, is there a minimum size each dynamic shape should have if I were to scale models down to really small sizes? I.E 2% of original size, assuming the parameters of the models' child script have been retuned for the new scale
Thanks!

This depends a lot on the physics engine you use, and its settings/parameters. For instance, with Bullet, you have a parameter internal scaling that can be adjusted in order to overcome some of the limitations.
