ARF
ASSEMBLY MANUAL
The new KatanaS 50E ARF was designed by Italy aerobatic pilot,
Sebastiano Silvestri and the design is based on of his successful
and famous KatanaS Tournament Of Champion’s airplane.
This professional ARTF kit is the result of Sebastiano’s long
research in 3D performance. This combined with an extremely
lightweight structure, the all wood airframe and the big control
surfaces give the KatanaS 50E an impressive thrust-to-weight
ratio and crisp control authority at any airspeed and flight
condition….That for this small class of airplane is revolutionary!
The KatanaS 50E can do it all…unbelievable easy harriers, torque
rolls, blenders, waterfalls and almost anything else you can dream
up are waiting you!
.....the only aerobatic limit is your fantasy!
