Done by a brazilian guy living in miami . The problem with this kit, as far as i know, is
that it has the nasty habit of snapping at take off. ( the 2 other kits built here in curitiba where lost
in the first flight) , so the original owner lost interest on it...

Having witnessed both crashes, i thought that it deserves a chance, as long some mods where built
on it. The problem is that i really like the a-4 ,and i want to stay as close as possible to the original ,
without changing too much its looks.

The full scale a-4 didnā“t have this tip stall tendency at all written in the history books, i think that the
slats where part responsible for this, so i drawed a fixed slat / leading edge drop on the scale wing.
Mr.patake worked so fast on it that i didnā“t have pics of the early opened wing structure... Also the
horizontal estabilizer where slightly enlarged too.

Letā“s see what will happen with this scooter!
