all it means is his high point of the ZIPPPPPP is a little further back
the kit was good, and at speed feels just as good as the current ARTF.
our club made a few Cornettos ( cheap Magnum ice creams ) with foam wings to improve the landing and about the same time the new foam winged ARTF was born.
the problem with flat wing is you need to fly at an angle to get lift which slows you down. i did alot of question asking and designed my own little Magnum with a foam wing, had a MDS 38 shoehorned into some balsa. was bloody quick, but a bear to launch because of its size. i forget the time scale of which came first, and who answered what.
