1: The Morpho turned upside down (extrados facing you):
- Place the 4mm carbon tubes in A (hold the bar at the end)
- Make sure that the B junctions are equidistant from the sleeve inlets and that the leading edges are properly tensioned
- Drag junctions C down their opening
- Check that the 2 mm rods are correctly pushed together in B ‘
2: Hold each wing at A and have the Morpho flap its wings so that it turns around and the 4mm carbon bars are pressed against the sail.
3: The Morpho at the place (intrados facing you) :
- Press in C ‘the end of the sticks of 2 mm. Check that they correctly tighten the throttle body (the body fold backwards)
- Check the general symmetry of the butterfly, for example: non-twisted wingtips, symmetrical body shape, equal antenna curvature, adjusted junction position
- Secure the loop of your D line with a lark knot and … have a good flight!
In order to be precise when inserting the rods at A and C ‘, the rod must be held as close as possible to the end.
(do not keep it far from the end)
How to set the Morpho ?
The flange joining the wings in C, is provided with a whip knot. This sliding and self-locking knot allows to modify the dihedral (angle formed by the wings) thus to vary the type of flight of the butterfly according to the conditions and your desires.
In open position, or wings apart: the butterfly is more hovering and more rotary. The resource is very long. Adjustable for use in indoor or near zero wind.
In closed position, or close wings: indoor, the resource is shorter but the relative flight is less easy. In outdoor or static flight (with wind) it is more stable and is more easily recovered during imbalances.
What settings and in what winds?
- From 0 to 5 km / h: The Morpho is a player, offering an acrobatic potential and developing all his poetry in his hovers and rotations (wing adjustment: open).
- From 5 to 10 km / h: Same as before, and becomes “static” (wing adjustment: medium).
- From 10 to 20 km / h: Standard wind range, the stability depends mainly on the quality of the wind (adjustment of the wings: closed).
- + 20 km / h: Flight more technical, ensure good symmetry and a more secure wing adjustment.
This setting provides control over the lengthening of the resource during gliding. The effect is very minimal and only concerns “indoor” driving. The use of ballast is associated with the wing adjustment and their effect is very variable and nuanced.
On each 4mm bars are slid a brass ballast. These weights are adjustable and can slide either upwards (towards the body of the Morpho) or downwards (towards the bottom of the wings).
In High Position: The center of gravity is moved to the center of the Morpho. The lengthening of the gliding flight tends to be longer and flatter.
In Low Position: The center of gravity is moved towards the rear of the Morpho. The lengthening of the gliding flight tends to be shorter and rounder.
The Morpho is a very weak kite. However for reasons of comfort and grip of the line during acrobatic flight, I advise you to use a line not too thin and with a strong resistance. For example, a line of 45 Kg or 70 Kg Dyneema type is suitable because its diameter ensures a grip much more comfortable.
I therefore recommend using a wire type Dyneema® or Spectra® 90Kg resistance. Made of polyethylene fiber, it is slippery and hardly heats your fingers.
/! The use of polyester yarn is uncomfortable. Indeed, it heats quickly in the fingers and easily causes burns. This suggests wearing protective gloves (not really ideal)
/! The nylon thread is very economical but also cuts the fingers, because often very fine. Only seasoned riders with this type of line will appreciate.
/! Kevlar (unsheathed) is strictly forbidden because it is extremely sharp and resistant.
Whether in static flight or in acrobatic flight, use a length of 10 to 20 m of line for low or no wind (- 10 km / h, 2 Bft) and 20 to 50 m for a medium wind or stronger.
