The Aeris 3A is a small agile low altitude stock plane. It is commonly used as a training craft, as it is very easy to control. The Aeris 3A appears to serve a similar purpose to the real-life BD-5 Microjet.
Its wing structure appears novel, featuring only a delta wing as its main lift wing. It further has 2 rudders on the edge of said deltas and 2 front ailerons.
