Yes, at our location, we do our hand signals which is pretty close to SSA standards.
Yes, if possible, we do radio. Not all trainers have a mounted radio, but may have a handheld.

We do a LOT of ground launch training before solo wing runner doing it solo.
Perfect!, nope.
Only perfect peeps I know are usuallly buttholes.

We do, we watch, we adapt.
We have a good record.
We are open to fine tune methods.
We are close to "SSA standards".
