Tail Rotor Alignment
Hi Guys,
I just bought my first helicopter and it is a Skyartec Ninja 400. Today I started practicing with the training kit and noticed that the helicopter has the tendency to go left. I try to correct this with the side pitch trim and more or less was able to correct it, but the trim position is almost all the way to the rigth.
Once I stoped practicing decided to give the helicopter a trough inspection. I noticed that the tail rotor is tilted 5+ degrees counter-clockwise looking from the rear of the helicopter. Is this intentional? Could this be making my helicopter go left?
Another thing that I noticed is that the tail stabilizer and the servo that control the tail rotorare also tilted 5+ degrees counter-clockwise. Did I get a poorly assembled helicopter? What other aligment should I inspect?
Regards

RE: Tail Rotor Alignment
If everything on the tail boom is tilted the same maybe your entire tail boom got turned a bit in packing or something. It should just be clamped in place, so you can probably just loosen it a bit and twist it. Everything should be good then.
But the tendency to go left is a function of the way RC helis are built, with the tail on the right. To counter the rotation of the rotor the heli will push the tail to the left, and in effect push the heli to the left. In a stable hover, if the heli is sitting still, that means the heli should be leaning a bit to the right. Different people probably have different opinions on how to accomplish this, either with trim or setup or just by flying it out. Its up to you really.
