I would be happy if it is 66 gm/dm as that will be quite a light wing loading.

If you look at this video you will see my Swift glider from Topmodel which is 3.14m and has a wing loading of 110 gm/dm at takeoff.

This is flying with the same motor I will be using on the Schapel.

I monitored flying speeds and G forces with this model and had positive 8G negative 5G and a max speed of 140mph. It lands quite slowly and predictably.

The heaviest loaded wing with my motor is the Opus jet that Ali flew. This was absolutely ballistic.

I expect the Schapel will fly faster than the glider but I will take measurements and report back.

Here is video of Andres plane. The engine he has is lighter than mine, also it has no
retracts. The retracts will help low it on landing and I will use crow with the flaps and elevons.
