Developing your flying skills to include more varied

maneuvers is exciting and rewarding.. The

ULTI-

MATE

is an extremely capable aircraft and is able to

do advanced stunts. Here are a few you might try.

ADVANCED AEROBATICS

KNIFE-EDGE LOOP

This maneuver requires a powerful engine

LOMCEVAC

Roll to the left or right and hold a bit (10%) of top

rudder. When ready to start the loop, add more rud-

der.

Start out in a 45º climbing knife-edge. If you are

using left rudder for the knife-edge, snap-roll left (full

left rudder, left ailerons, and up elevator) 1-1/2 turns.

Then, holding full left rudder, give full down and right

aileron. Timing is the key, as well as power and

climb angle. Try it and hold on!.
