A second model was constructed, built for pilots up to 6' 2" (188 cm), which became known as the Micro Mong.

If equipped with a Rotax 277 engine, the aircraft meets American FAR 103 Ultralight Vehicle standards, by weighing less than 254 lb (115 kg).

The wing area of the ultralight version is larger than the heavier Mong Sport it replicates, in order to keep the stall speed low.
