Rotorama Meffie Nano ARF is a set of unassembled small copters for 2.5" propellers. Although the Meffie is designed primarily for indoor flying, you will enjoy a lot of fun even outdoors in the park or in the garden. Meffie Nano is made for 16x16mm stacks and nano sized cameras. The frame itself weighs only 16 grams, making the whole copter very light (our reference set weighs 78 grams) and, in combination with 1204-1106 engines, also fast.
