Flying to a Scale Schedule
Any flyer can take their scale plane to their local field and ‘hot dog’ it around (presumably for the flyers ‘stress relief’ instead of ‘kicking the dog’) but ask yourself these questions: is this flying style improving flying skill? (doubtful – except if averting crashes becomes habitual) and, is it pretty to watch? (doubtful – did the real plane fly like that!).
To fly your Scale Aircraft in a ‘scale like’ manner requires Practice (repeated exercise to improve skill), Patience (calm endurance) and Persistence (continue firmly). Even Practicing to a Plan (method thought out in advance) can for some, be helpful. In this section we will deal mainly with flying the manoeuvres usually found at a scale comp.
* All flying manoeuvres must be judged bearing in mind the performance of the full size prototype. The aim of the scale flight schedule is to recreate the flight characteristics of the full-size aircraft. Judges must not therefore confuse scale contests with aerobatics contests.

Below is to be used as a guide for F4C, Large Scale and Flying Only competition.
Based on the above the current rules allow for a flight schedule with a total of ten manoeuvres, with Take-Off, Figure 8, Descending 360, and Landing being compulsory. Please note that Figure 8 and Descending 360 can be flown in any order of the eight manoeuvres between Take off and Landing. Please note Take off and Landing have the same K Factor.

Take-off is the first compulsory manoeuvre and is the second highest scoring and should be performed similar to the real plane (within the limits of the judges field of view and area of the flying field).
Approach & Landing is the only other compulsory manoeuvre and may be a 90 degree turn or semi-circular turn from base leg to final leg when descending through to touchdown and landing into wind is allowed. This manoeuvre has the highest flight points and when done properly is great to see (especially for the pilot having just flown some of the above manoeuvres this gets to be the best one – and when he gets it right, the great feeling of satisfaction).
Figure Eight is a manoeuvre that consists of two circles of equal dimension joined together side by side with no X in the middle. Takes practice to get this one right.
Descending 360 Degree Circle starts as level flight down the strip at height and when model is centre to judges, power is reduced to low setting and plane banked to descend in a circle and exits at 6 metre height on same heading as entry. Pretty to watch when done well.
