In the yahoo group archives I found this also.
,
I'm using 85% ATV's on ail. and elev. with the links on the servo arms spaced at 27mm. I can use about 3/4 of the stick
travel into the corners of the gimbal, before the swash plate binds. I also raise the washout assy. by shimming the two links
with a thick small washer about 1mm in width, this raises the washout arms up a bit so there is less binding from the arms at
full cyclic-you can also relieve the underside of the arms to clear the upper swashplate edges. Just remove the blades and
rotate the head slowly while you select full ail. or elev. or some of both, at full high collective. This is where you will see the
washout arms bump into the upper edges of the swashplate. Also make sure the arms are turned over 180 degrees, with the
flat side outward, to give you more clearance. Take a look at full collective for the position of the washout arms. This is
why I like to use the 710mm blades, especially with the 80 eng. I can get +10.5 and -9.5 degrees of pitch with no binding with
3/4 stick travel into a corner of the gimbal. It's very rare to have a stick fully into a corner, and this will cause some serious
binding.
I do wish some improvements were made for this design, maybe CCPM is the way to go? I doubt Robbe will make this
leap. But all in all, it works well if one stays in limits.
Thanks,
Phil |
