The new zinger winger II will be between the sizes of the mini and the field trialer. There will only be room for a 209 primer and the housing for the release is re-worked. Otherwise pretty much the same design.
Just got two uplanders...talk about chunk a mark!!! I will use them for upland,as well as diversions and marks,along with the three zinger wingers.They are small and light so I can take them with me to the Grand to train between tests without sacrificing space.
