Inverted Nose In Circuit

Description
This circuit should be flown as flat and slowly as possible with consistent height and accurately centred. The nose of the model should be pointed to the centre of the remote circle as shown in the diagram.

Preparation
Fundamental to this manoeuvre is good control with the model inverted, so an assessment of your inverted skills is important before deciding to attempt this manoeuvre. If you are able to hover your model tail-in, nosein, and side-on in both directions, then you are in a strong position to continue. Once you have practiced these 4 points of inverted hovering, try these exercises at various points of a remote circular circuit of about 30 m diameter. When changing orientation from tail-in to side-on, nose-in, etc., initially use a slow 90º pirouette. You have now proved that you can control the model in all orientations required through the manoeuvre. The next step, I would suggest, is to return to an inverted tail-in hover in front of you and then begin some slow pirouettes. During these pirouettes you will be utilising your previously acquired skills to master cyclic control at all points of the pirouette. Your aim now should be to slow the pirouette as much as possible, aiming for about 20-30 seconds for the full 360º.

The next step is to carefully and slowly introduce some aileron input to produce a sideways motion during the pirouette that will now produce a ‘nose-in’ circle. These initial nose-in ‘circles’ may not be particularly circular and maintaining the required nose-in orientation is likely to be difficult, but if you are able to keep the model moving sideways through the circuit, then improving accuracy is only a matter of practice. The final step is to develop the necessary symmetrical circuit that remains accurately nose-in and retains steady height and sideways speed.

Possible Problems
Maintaining an accurate inverted nose-in remote circle is always challenging and especially in wind. In this case, a pronounced aileron input is required to keep the model moving sideways into wind with a reduction necessary when downwind. A conscious effort is always required to maintain the nosein orientation with tail control. Care must be taken to keep the speed of sideways movement under full control. Many problems begin when speed increases and sudden corrective actions are required. The aim should be to maintain a slow steady speed throughout with gentle control movements. Before commencing the start of the manoeuvre, get the model inverted and move it around for a few seconds to familiarise yourself with prevailing conditions. Do not rush the start and I would suggest establishing the model in at least part of the nose-in circle before the start is called.
