Kadet MkII Model Airplane


The KADET MARK II has provided thousands of fledgling R/Cers with their first success at radio control. The .40 size KADET MARK II is a full-house 4-channel trainer with ailerons.

You can't go wrong with a KADET! For over 25 years, the SIG KADET has been helping new R/C pilots earn their wings. It was the first model airplane on the market that was designed from the ground up for learning to fly R/C.

A SIG KADET has all the features a good trainer needs.
