Here is the home made swash tool leveling for my Hawk Pro. Do not need to take the rotor head off, slips on and up against the shaft to allowing squaring of the swash to the main rotor shaft. Note the extra small hole is not used, a tappped hole from another project.

No, the Raven has a completely different control system.

My Posts This: Topic  Forum		SteveH, just to confirm

With the rudder servo at static pitch (rudder servo center of travel) the tail rotor blade should actually be pointing along its cord to the right paddle? (see diagram) thanks


>>>
When you setup the static pitch on the tail rotor (pitch at the center), the way I like to do it is put the system so the rotor blades are parrallel with the tail boom of the heli (one blade straight ahead and one blade straight back). Then with the tail rotor such that one tail rotor blade is sticking straight up, sight down the cord of that tail rotor blade toward the flybar, and adjust your linkage so the line of sight down that tail rotor blade points to the flybar paddle on the Right side of the heli.

This will get your tail rotor pitch set in the ball park for your first flight. This setup will work on any clockwise (right hand) rotation heli.

My Posts This: Topic  Forum		linkages' length of a Hawk

If it's not too much trouble, can someone posts his(her) linkage lengths of your Hawk, please? That would make the setting much simpler

Thank you,

My Posts This: Topic  Forum		Ammarin,

Using the set-up procedure that Steve describes in the "sticky" at the top of this Century forum, is one the best way to go about it because just giving lengths would not take into account all the different servos and the differences between where their output shaft centers are from the front of the servo

My Posts This: Topic  Forum		Parts...

Pitch gage should be easy. Anyone that sells heli's should have one. HeliProz is a good one to check with. Century also has one. If you look at Heli-Worlds parts list for the Hawk Pro/Sport/III you should be able to find almost any part you'll need. Of course some parts may be discontinued or have been upgraded.

My Posts This: Topic  Forum		Hawk III parts are still readily avaiable through any hobby scorce that has an account with Century. As you are in the USA - I would suggest Rick's or Heli-World.

As many parts are comaptible between the III and Pro, If you know the part number you can also check at Tower Hobbies.

My Posts This: Topic  Forum		Steve,
I know that this post is over one year old, but I have a problem that I don't seem to be able to fix.
If I set my Hawk up as you suggest, one blade has a different pitch than from the other at the center stick position. This can be more than 5 degrees.
If I want to make the pitch equal, it may take Rod C a 3-5mmm adjustment at one side to do so, something I don't think is right.
I thought that if all the rods that are supposed to be equal are just that, the pitch of both blades move the same amount. OK, one might be a little off, to be ajusted in the field. (aka Blade Tracking)
What is going on? Did I miss something? I checked the setup several times with no avail.
I have two indentical Hawks, both show the same problem.

My Posts This: Topic  Forum		Hey I cant speak for Steve but I have done this set up more than a few times. You must have missed something. If your blades have different pitch, it could be the short rods connected to the bell crank (up on the main grips) or the other links that go to the swash (from the same B crank). Start from the bottom and work up. All three bell cranks (ele. and both alerion) need to be square to the main shaft. Those are in front of the main shaft and right above the crown gear. The two push rods from the aileron cranks to the shaft are equal length and long enough to make the swash level (center stick). Then make your collective P/R, with servo centered and arm at 90, the right length to center the elevator assembly in the frame (same movement up as down). Important the short P/Rs on the main grip are the same length. Then take the P/R from the swash to the main grips and make the blades read zero pitch at center stick.
Another possible cause here is the placement of the balls on the aileron servo round arm and or bad centering of that servo. The balls should be forward of the center hole (servo screw hole) (forward being closer to the nose of the heli) Look in the book I forget the spec. those ball locations need to be equal, same amount forward and same amount out from center (left to Right). When that servo is centered, a line thru those balls should be perpendicular to the frame. This could very easily be the cause.

Go back over it...you've made a mistake. If you come out with blades 5 degrees different in pitch, you've definately made a mistake.

My Posts This: Topic  Forum		Update of my problems with set-up
Time has passed, and I have still not found out why both blades are not deflecting the same amount as they should.
Have checked several times all the lengths, to make sure I did it as instructed, with no difference in results. Finally decided just to adjust one of the linkages until the pitch was the same at both blades and flew it that way. It is still a mystery to me what is going on. I must have made a mistake somewhere, but I do not know where. Unfortunately, I have no one here to check my work.
I might try to post some pictures of my setup and see if someone can see what I did wrong.
