Chapter –XI Assembly of Electronic Parts ( V-Stabi / receiver / controller / batteries )At first mount the electronic box of the V-Stabi 3 axis system in an upright position to the tail servo using a double-sided tapewith a maximum strength of 3mm. The connection plug board for the servo and receiver connections is to point to the leftside. Place the housing as far as possible at the right side without touching the chassis, so that the plug later has enoughspace and the harness does not protrude too far from the chassis at the left side. If you look at the box from the side, it mustbe located in the centre on the servo.The sensor box is attached to the provided base plate using double-sided tape.Attention! The box has to be placed at right angles in the chassis. Otherwise sensor inexactnesses occur later during theflight. When attaching the box simply place a ledge serving as a stop at the rear edge of the base plate. Then push the boxdown along the ledge until it rests on the plate, so that a sufficient rectangularity is achieved. The cable of the sensor box hasto point to the front.The receiver is also attached to the side area of the tail servo in an upright position with the connection plug board pointing tothe left side. Check before if the length of the short connecting cable is sufficient. When using a receiver with a connectionplug board on the upper side, it is recommended to mount the receiver such that it points to the top. Otherwise the length ofthe connecting cables is not sufficient.The assembly of the electronic components looks simple, however in practice it has proved its worth because you can accessthe connections in every situation and from both sides. In addition, the connecting cable to the PC can easily be plugged infrom the right side. For repairing purposes the entire unit consisting of the tail servo, the electronic box, and the receiver cansimply be pulled out of the chassis from the back by only loosening the two tail servo attachment screws.On the following page you can see some photos concerning the laying of the cables. The cables may not protrude too farfrom the mechanics because the canopy is located very closely to the arched rear edge of the chassis.A detailed description of the connections can be found in the next chapter. In addition, the complete programmation of the V-Stabi 3 axis stabilisation will be described.32
