General Info

This model is based on a 180hp retro fitted PA18 Super Cub.

The CA18-1920 has a maximum all up weight of 1920lbs.

To accommodate the increased load capacity, the timber framework within the fuselage along with the wing spar caps have been increased in size.

This model is an ideal platform to fit a STOL kit for those shorter and rougher landing areas.

CADL will be offering STOL components for this model by the end of 2016, the components will include:

- Fibre glass hoerner style wing tips

- Carbon fibre leading edge coverings (to replace the plywood)

- Carbon fibre wing ribs

- Fowler flaps

- Modified undercarriage
