Thank you for choosing the
Jumper 25
ARTF by SEAGULL MODELS. The
Jumper 25
was designed
with the in ter me di ate/advanced sport fl yer in mind. It is a High-wing aeroplane which is easy to
fl y and quick to assemble. The airframe is con ven tion al ly built using balsa, plywood and veneer
to make it stronger than the average ARTF , yet the design allows the aeroplane to be kept light.

the correct lengths, the motor mount has been fi tted and the hinges are pre-installed and pinned
for security. Flying the
Jumper 25
is simply a joy.
