Check that the recess in your washout arms faces out, they are flat on one side and recessed slightly on the other.

Having them the wrong way round as mine were puts the swash phasing out but is only really apparent if your flying 3d.

To turn them round you will need to press out the pin in the dog leg links and turn the links round.

I know it's not just mine because I've seen a picture of someone else's on the net where they were on the wrong way.

I will try get a picture tomorrow. Its quite simple, the recess in the washout base arms needs to be on the outside.

The part in grey is the recess I am talking about:
(didn't have the heli in front of me when I drew this so it won't be exactly the same but gives you an idea!)

The arms aren't symmetrical so turning them round effectively puts the arm further inwards towards the head block (always called it a washout base but not sure this is the correct terminology on a fbl head as it is incorporated into the head block). This swings the inner swash round slightly and puts it in line with the rest of the head as it should be.

Just noticed the picture on the front of the manual and it shows the arms with the recess showing on the outside. You can see it more clearly in the exploded drawing in the back of the manual so mine were definatley on the wrong way.

Anyone check theirs yet?

My washout arms are on backwards according to what Richardmid1 is explaining as well.
Are they coming this way from the factory?
I broke 1 in a crash last fall & the replacement came the same way.
Can someone post a good photo of the washout arms on an original rotor head so we can compare?

Found this photo on another site & it shows the arms the same way mine are installed & the same way the replacements came.

Which way is correct ???

That is the INCORRECT way in that link! I saw another 300X at the club today and checked it out, sure enough the arms are on the wrong way! Man there must be hundreds of them out there like this!!

Yes the AR7200BX will correct things in flight but its just not right!

Mine had the recessed part facing inward but my old eyes can't tell the difference :-( having said that I did make the change as per your tip.

Thanks,

Gord.

Yours are correct Drev. the front of the arm is be in the lead of the rotation. I just looked at mine and there is a difference in the way it goes on But I believe the ones in Drev's picture are correct if you flip it over it over it may be to close to the frame? I think the picture in the manual is wrong. manuals and real world have never been exact.If you check the picture in Horizons site of the 300 it shows it like Drev's. Every picture i can find has them like this. I just think the manual has some bad artwork?

Look at the arm from above the heli, they are offset/not symetrical (not from each other), by turning them round (the way they should be!) the arm screws back onto the head block closer to the head block, this spins the inner swash round slightly relative to the head (phasing!).

The recess in these arms does absolutely nothing (saves about 0.01g which wasn't the purpose), its purely visual, why would they put it facing inwards?!

You think they built the heli and then drew it?! No, the heli has COME from drawings using CAD or something, whoever put the arms together did it wrong, not the drawings.

manuals from made in china helicopters have been wrong since the start of time. So yes the picture is more than likely wrong but a call to Horizon would be in order. The manual it self have amendments made to it.

The manual has 2 different pictures showing these arms both show the recess on the outside!

Even if the picture was wrong the fact is THE ARMS ARE THE WRONG WAY ROUND IN THE 'REAL WORLD'!!

Richard is correct about phasing. the closer to dead center is optimal. If flipping the part improves this alignment, its more correct, regardless of the manual or what anyone at Horizon says.

There would have to be some reason to put them out of optimal alignment.
I cant think of any reason, unless Horizon can offer up some reasonable explanation.

Follower Arms
I did talk to HH and they did confirm that the arms are correct in the position that they came in. The hollow is to be on the inside. As it would move the lower part of the arm closer and put it at a slight angle. My personal 300 has the metal arms and they also are in this configuration. They HH is going to call me back to confirm this with someone at a higher level but for now they would not recommend this change.In the same conversation it seems that it would very unlikely make much if any difference either way.

Head phasing is something that has to be quite precise! Im shocked but not totally surprised by this comment from HH!

The fact is it is wrong and if it is indeed ALL 300X's out there I highly doubt they will admit to it so I can guess this person at a 'higher level' will also say it is fine!

I think you would be surprised how open these guys are to finding the resolve for these issues. Most if not all of these Reps are in this sport and like myself have a responsibility to the hobby to make it right. People need to call them more and things would have a better chance to be resolved. Just posting here does not get anything fixed,especially in a case like this. If people call it will be documented and the tech guys look at all of those documentations. So even though it is great to come here for help and info, but a call to HH will help at a higher level. I work at a LHS and even if it means not selling a product I tell the truth the best I know it and these seem to have the same goal. So call and ask.

I'll be leaving mine the way they came from the factory.
I don't fly 3D & have no interest in doing so.
The bird flies just fine the way it is for my capabilities. Why take the chance on breaking something to change them around?
Never did or will completely trust any manuals no matter what brand or product they cover.

if youve flown an Align 600 (cant say for sure about the other models) youll know the difference in phasing and what that can do to your flight. Granted much like the HH gyro covers up some poorly setup mechanicals, so too does the Beastx hide a less than perfect alignment/phasing. That still does not make it (OK) right.

As these things go, I am a beleiver that if your mechanically on point, the electronics (gyros) will have less "work" to do which can be measured in the efficiantcy (or loss of) by the amount of draw on the battery. Length of time between charging. (talking rec. battery) eg: if the servos are working your gyro more vigorously, its a waste of energy. You might not notice it, but you might as well, certainally your flight time will suffer.

Remember the wing issue with the HH sold Parkzone BNF extra?
The wing appears to have a reverse or upside down wing airfoil?
They never admitted (I dont know who they are) it was an issue.

All the reports I saw said this was intentional, but many pilots flipped the wing and achieved a better landing plane.

Just saying....
