Indoor Pattern, or F3P, is
PRECISION AEROBATICS IN A VERY RESTRICTED SPACE
The highest International standard is currently the FAI (FEDERATION AERONAUTIQUE INTERNATIONALE) provisional F3P class.
Here is some cuts from
FAI Sporting Code
Section 4 – Aeromodelling
Volume F3A
Radio Control Aerobatics
2006 Edition
5.M.1.1 Definition of a R/C Indoor Aerobatic Power Model Aircraft
Model Aircraft, but not a helicopter, which flies indoors (usually a hall) and is aerodynamically manoeuvred by control surface(s) in attitude, direction, and altitude by a pilot on the ground using radio control.
5.M.1.2 General Characteristics of R/C Indoor Aerobatic Power Model Aircraft
Maximum total weight.......................................500g
...
Power source limitations: Any suitable power source may be utilised except those generating any kind of exhaust emission.
...
Each pilot is permitted one helper during the flight.
...
The manoeuvring area is limited by the floor, ceiling, and walls of the hall, as well as by the safety line (the line that the judges are seated on). A model aircraft must never cross this safety line. ... The recommended dimensions of the hall should be about 40 x 20 metres in length and width and between 8 to 12 metres in height.
...
If a model aircraft is unsafe in the opinion of judges or being flown in an unsafe manner, they may instruct the competitor to land.

5.M.1.14 Description of Manoeuvres for Indoor Aerobatic Power Model Aircraft
All manoeuvres are judged on flight path and will start and finish in straight and level upright or inverted flight. Centre manoeuvres will start and finish on the same heading, while turn-around manoeuvres will finish on a heading 180° to entry. When appropriate, entry and exit of centre manoeuvres will be at same altitude. Positioning adjustments in altitude are allowed in turn-around manoeuvres.
All manoeuvres which have more than one loop or part of loops will have the loops or part loops of the same diameter and in case of consecutive loops, in the same place. Similarly all manoeuvres which have more than one continuous roll will have the same roll rate. All manoeuvres which have more than one point roll will have the same roll rate, and points will be of equal duration. All consecutive rolls on a horizontal line will be at the same altitude and heading.
All manoeuvres with rolls, part of rolls or snap rolls, or combination of same, will have lines of equal length before and after the rolls or combinations except in Immelman or Split S families. Snap rolls that are not snap rolls (i.e. barrel rolls) will be scored zero. Spins that are spiral dives or have a snap roll entry will be scored zero. Any violation of above will be reason for downgrading, ...

There are easier classes at national or local levels.
F3P rules also recognize Aeromusicals or Freestyle competition. The judgement criteria are:
1 Flying Style
- Precision of manoeuvres
- Utilisation of flight performance scope
- Variety of manoeuvres
2 Artistic Quality
- Synchronisation to music
- Continuity of Schedule
- Sequence of quiet and dynamic phases
3 Overall Impression
- Utilisation of manoeuvring area
- Positioning
