Now with the AS33, the trend towards higher wing loading continues.

If you have 18m and open class in one competition (which is often the case), tow planes should be capable of towing 60kg/m² gliders at a safe speed with decent climb rates. They should also allow for 850kg MTOW on the rope for the Nimbus 4T waiting in the grid. There are not so many tugs available with this combination.

What would you consider to be a safe aerotow speed with a 21m-JS1c when fully ballasted?
