Stik has it right..
Reverse half cuban with Tumble on up 45 is a bad figure to use near the ground, as you can not always guarantee you height at the end of the gyro. As you can see from the vid he came out off heading and he had to roll to align with his A axis, which unfortunately cost him precious height, and room to recover.
Gyro's need to executed after a long upline away from the ground, ie Fig 1!
Reverse Half Cubans need the first 45 deg line to be flown accurately otherwise you will be low on your gate at the top every-time..
Get trained fly safe
