Assembly of bagged V-tail

 

Suggestion to glue of the sticking for bagged V tails, adaptable to gliders Minij and Prodij gliders (but also in to any other glider of equivalent size).

 

For evident obvious reasons of transport the V-tail are is delivered in 2 parts.

The sticking in 110 and the installation of control horns are in charge to the userthe user will have to glue them together at the right angle (110) and place the control horns. To do it so, a piece of glass fabric is supplied, as well as ball links with 2mm metal rod forced in for the realization of control horns. A template in 110 shape will be necessary to assemble half athe stab partss together to the right angle.

 

Remark:

PRODIJ:

Oas on the Prodij fuselage the base of the Vtail being alreadyhas a V shape, the 2 half stabs can have to be sanded in bevel (55), assembled in the adhesivewith tape oin the intrados (Vtail in flat position), and then stuck on to the right angle, edge has to edge by the extrados.

Only the a band(strip) of glass fabric in on the extrados will turn out necessary, as the intrados of the Vtail will be stuck on the base without any need for supplementary reinforcement.

make holes in the intrados of the control surfaces to insert the control horns (as indicated in the corresponding building directions glue them with cyano.

Sand the fuselage base and glue the stab on it with cyano.

 

MINIJ:

First of all, the 2 half tails will be carefully assembled edge to edge in on the extrados by a simple mere piece of adhesive tape, which has to overtake jut out on both sides to avoidprevent (coulures).the glue from running.

The tail then is turned over on the template V shape giving the good right angle,; a net thin line of cyano is applied ion the joint.

Add so as much of cyano thatas necessities necessary (the accelerator is very practical to make it set faster) to fill in completely the space between the 2 stabs.

Sand then the base to make it as flat as possible (take care not to not decrease appreciably too much the thickness of the stab in this place what which wcould weaken the joint).

Place a 2cm wide strip of glass fabric of 2cm wide on horseback(by horse) on the joint; tighten (stretch out) the fabric by Scotch-taping it on every each half of the stab (the adhesive tape is to be taken put on 1mm of wide of fabric).

Soak (fill) the fabric with cyano without excesswith moderation; by capillarity, the cyano will infiltrate even into the fabric under the adhesive tape.

removeRemove the adhesive tape once the cyano driesis dry to the touch.

 

In On the extrados, remove the adhesive tape then apply place a 1cm widea band(strip) of fabric(tissue) of 1cm wide.

Soak (Fill) in it the same way the band(strip) of fabric byand use using a some metal flat(dish)plank (spatula(spoon-bill), blade of a cutter) to force the fabric in to get the necessary angle.

The stab is now assembled in a strong enough way not to not risk to break in its the middle.

 

Realize heavy lossesMake holes in the intrados of the control surfaces to insert the control horns (as indicated in the corresponding building directions). Flood glue them with the cyano.

Sand the fuselage base and glue Stick the stab on it with cyano.

A leave online of resin + microballoons on each side of the V tail will strengthen the stickinggluing of the Vtail on the fuselage.
