Hello Hobbyco,
The main thing that determines the minimum speed of an airplane is the wing loading. The size of the wing vs the total weight will determine the minimum speed. To a smaller extent, the airfoil shape of the wing has an influence on the minimum speed. A slow flyer model will generally have a wing with an undercambered airfoil, or one that is concave on the bottom.
Cheers, Dave

What is the total weight of the plane in flying condition?
