I know this has been covered in a number of threads but I've had a search through and still find lots of contradictions. So I'd appreciate a defininitive answer to how they should be installed. So here are some questions:

Q1: SWASH - What should be connected to the long balls. Radius Links or Pushrod C?

Q2: BELL MIXER ARM - What should be connected to the long balls. Pushrod I to seesaw or Pushrod C to swash?

Q3: FLYBAR CONTROL ARM - Which direction should this be mounted. So Pushrod I is inside it or Pushrod C is inside it?

Q4: BELL and WASHOUT ARMS - When should these be level? I'm using 3/4 stick hover, so I'm assuming that I should set these level at half stick/0 deg pitch.

Issue 4 is giving me the most concern. To acheive this I have to shorten the seesaw arms considerably past the manual recommendations. In fact they end up so short that they link bodies are almost touching so the pushrod cannot be made any shorter.

TO THE CENTURY REPS
How about putting a clarification statement about the head configuration on the web site.

I treally appreciate the help. Although the guys at my club are friendly enough, they Raptor fliers. Comments range from the "sorry I don't much about Century" to the the "you should have got a Raptor" - so this forum is my main source of assistance. With hindsight a raptor would have been a better choice but I think the Hawk is a very good machine and am going to stick by it.


Cheers,

Nigel

Nigel,

In an effort to eleminate all confusion, I'm attaching a picture I just took of the control rods on my Hawk.

A1. The long balls on the swash go to the rods that go to the Bell mixers.

A2. The long balls on the mixers connect to the balls on the seesaw.

A3. The link from the mixer to the seesaw should be inside the flybar control arm.

A4. The washout arms should be level at 0 degrees pitch. I attempt to level the mixers at 0 degree also, but this is not always possible and really not all that important in my opinion. It is much more important to have the proper pitch range.

I almost forgot to add that my Hawk has been upgraded with the aluminum head center piece off the Falcon SE V2, but that in no way changes the control links.

I hope this clears it up totally, but if you have any more specific questions, I'll be happy to try and answer them.

I seem to have the same setup as you. I didn't know there was more than one way of doing it!!!

Rawlie,

Yes, there has been some confusion on where some of the links go since the introduction of the Hawk Sport because they talk about some different options in those instructions.

The only thing that I have done differently on my Falcon, which has the same control system as the Hawk, is to change the short balls on the inner side of the swash where the washout "A" arms go, to long balls. This speeds up the cyclic response a bit. Other folks have installed longer balls on the seesaw for the same effect.

I have found with all long balls on the inner ring of the swash, and the Predator black paddles on my Falcon, it's PLENTY fast for me.

Rawlie,

Yes there has been some discussion/confusion on the control system set up since the Hawk Sport came out. There is at least one statement in that helis instructions that discusses some options.

The only thing I have done that seems to work well for speeding up the cyclic on my Falcon is install all long balls on the swash inner ring. This with the addition of the Predator black paddles makes the Falcon PLENTY fast for me.
