RE: PL-12 Airtruck
So I haven't worked on it as much as I would like lately but here is my progress from last night and today. Servo trays are made and installed. Lower half of wing is sheeted. Still have the other wing to do.
The servos were a hassle because of the limited room in the wing. A standard servo will hang out the bottom and top but if you lay it on its side it fits. When you do that there isn't enough space between the ribs to get a clevis on and off easily and since the control arms and rods are all hiden I need to get to the clevises. After seaching around I found Hitec HS77BB's they are a perfect fit. They rated at 61.1 oz/in of torque at 4.8V; 76.3 oz/in at 6V Speed: 0.18sec/60deg at 4.8V with no load; 0.14sec/60deg at 6V with no load. Basicly they are retract servos without the end limiters on them. And they only measure, Length: 1.73" Width: 0.90" Height: 0.98" so they fit in real nice without being overly expensive.
