The Hummingbird 2 is our 2018 update on an already amazing calm-wind Aussie Round Rang: a must have in dead calm conditions. The new version has slightly wider tips for more range. The lead wing has been swept forward which keeps it turning in towards the bullseye. In calm, throw low and laid-ou. The Hummingbird 2will peak high at 50 meters then come screaming back to the bullseye. However, this new version also works well in medium winds. Just throw more vertical and a little higher. Made of 3.2mm G-10 fiberglass. The material is very dense and thin giving it the extra weight and small amount of drag necessary to make it all the way back without the help of the wind.
