Carl Goldberg GBGA1053 - Manual (Page 30)

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!. 30
