Application(s): Used for ailerons in DLG as well as rudder and elevator.
Comments: I initially compared them to D47s because of their appearance, but that's completely wrong.
They worked okay initially, but after only the first flight the left aileron servo started pulsating up and down when pushed to the upper extreme. After a few days more of flying, the right servo began jumping to the lower extreme. This happened usually in-flight, but it did on the ground occasionally. It's pretty hard to fly a plane when it wants to execute a full roll-dive into the grass from 100 feet up :(
Anyways, these days the right aileron servo freezes up every minute or so. It's less than a month old and has never been moved by hand (strained).
As elevator and rudder they worked, but only in a mediocre fashion. The rudder wouldn't center well and the elevator was extremely sloppy, although to be fair this was probably because of the linkage.
The elevator servo locked up once, sending the DLG into a full-out dive from 70 feet. Snapped the pod clean in half.
Finally, they arrived covered in some kind of oil or grease. Made them pretty difficult to mount. And no, I wrapped them in tape; I'm not some kind of newb who would get CA up in the gears...
It should be noted that they only provide 1.2kg of torque as compared to the D47's 1.5kg.
