FS70 Surpass
The
original FS-61 was in production for some five years before it was replaced by
this totally new, more powerful engine. With its advanced design, it shares many
of the features of the larger FS-91S and has four ball bearings, special prop
locknute and silencer included as standard. Ideal for powering aerobatic, sport
and scale models where the increase in power over a .61FS is required. Designed
to be used with 11"x8~9" to 14"x7" propellers.
