The technical solution of the utility model is: a kind of adjustable teaching hand-thrown model of an airplane of center of gravity comprising fuselage, machine
The wing, empennage and at least one clump weight, the counterweight mounting groove of the fore-body setting strip, the clump weight is movably
It is set in the counterweight mounting groove, the waist is provided with wing slot, and the wing pierces into and is connected in the machine
Wing slot, the fuselage afterbody are provided with empennage slot, and the empennage pierces into and is connected in the empennage slot.
It preferably, further include fuselage reinforced sheet, the two sides of the fuselage are respectively fixed with the fuselage reinforced sheet.
Preferably, one opening of head setting of the fuselage reinforced sheet, the position of the opening and the phase of counterweight mounting groove
It is right, and the opening size is less than the counterweight mounting groove.
Preferably, the fuselage reinforced sheet is provided with same wing slot in the position opposite with the wing slot.
Preferably, bayonet, the machine of the bayonet and the fuselage are respectively provided in the middle part of the leading edge of the wing and in the middle part of rear
The clamping of wing slot.
Preferably, bayonet, the tail of the bayonet and the fuselage are respectively provided in the middle part of the leading edge of the empennage and in the middle part of rear
The clamping of wing slot.
In conclusion the beneficial effects of the utility model are: the adjustable teaching hand-thrown model of the center of gravity of the utility model flies
Machine is simple and reasonable, and center of gravity may be implemented and adjust on a large scale by back-and-forth motion clump weight, or change counterweight number of blocks.And
Position and the quantity of counterweight can be observed directly by opening, it is easy to operate.
The utility model is described in more detail below by embodiment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the utility model embodiment middle fuselage and reinforced sheet structural decomposition diagram；
