The Bunt.

Otherwise known as an Outside Loop, this is a loop which pulls negative g compared to a normal loop which pulls positive g. Normally, this is done by diving towards the ground initially but for first practicing this manoeuvre, we suggest you go upwards first. For a given size of loop, more down elevator is required for a bunt than up elevator is required for a normal loop. Both types of bunt are shown.

This manoeuvre is best practiced going downwind. The reason for this is that once you are about halfway round, the wind direction 'helps' the model climb through the second (top) part of the bunt.

To get a feel for using down elevator in a bunt, we recommend trying this manoeuvre first. This is really a normal loop but instead of entering and exiting the manoeuvre upright, the model is rolled inverted and a negative g loop is flown. The advantage of this is that the model goes up first so your margin of safety improves. A real bunt offers the thrill??? of being inverted, heading for the ground and at no great height. The resulting hole in the ground can be impressive! Going UPWIND , with wings level and at about half throttle, half roll to the inverted position. Open the throttle and push in down elevator to start the loop. Flying through the loop is exactly the same as for a normal loop except that down elevator is used instead of up. When the bunt is complete, half roll to recover.

Now for the true bunt. Gain plenty of height before starting this manoeuvre. Head DOWNWIND .

With wings level, completely close throttle and push in some down elevator to start. As the model approaches the vertical, increase both throttle and down elevator to go through the bottom of the bunt. Open the throttle fully to climb. As you pass the vertical, decrease down elevator as gravity will help to round off the bunt.
