Ettore Mancini from Italy has designed a very nice shut-off system.

It can easily be retrofit into you existing models or build into new models. The best part is that he is going to make a small production for sale !

Contact Ettore Mancini for more information.

Update: AA F2D SHUT OFF 2010


Ettore Mancini:

This mechanism works with the concept of levers and arms rotation, in practice, the strength of the spring is reduced by 1/5 and then at 400 g tractive mixture of the tube is closed with a force of 2000 g.

The total weight of the shut off is 25 g and not change the behavior of the model because it is mounted on the center of gravity.
To mount the shut off it is enough to make two 3 mm holes on the central rib.

The concept of the system is simple but it is very difficult to build the wings with the right cams.
That is why I designed them and I made the laser cut so that the components work well.

To block the open system with one hole with a 2 mm pin steel threads, though careful to #5 photos you can see it near the tube of the fuel.

Before launching the model simply pull the pin and the system begins operation.

I will make a production of 50 pieces for sale at around 20.00 each. 15.00 for more than 10 pieces
