Doing my pre-setup installing the servos in the frames with no problems. I have not put the arms on the servo's in the final 90 position. It seems it will require a bit of force to seat the arms properly and it will be tough to remove. Any sugestions on how to get the arm's on right the first time? Has anybody removed a small amount of shaft diameter with a file to soften the fit?

I wouldn't remove ANY diameter, you will want the tight fit with that amount of torque.

If you just lightly press the arm on the splines, then check the alignment. Then go to the next spline if you're off until you find the correct alignment. After that just press HARD to seat the arm onto the servo shaft/splines.

I use JR HD servo arms and they are even more difficult to push onto the servo. But they will not slip or strip the servo arm splines.

I like the tight fit with that amount of torque.

To hover is divine, the alternative is rather PLANE.

I used a longer bolt (M3), with a nut and washer. Once you have the arm lined up as you want, just screw the bolt into the servo shaft (don't tighten it), then draw the arm on with the nut while holding the bolt with an Allen key. That way you are not placing any force through to the servo gear train.
