600 Going in and out of Track

[Andy from Sandy]

Which screws came loose.

The ones that go through the frame and into the bearing blocks.

Where exactly are you thinking?

Probably talking about the locking collar to stop up and down movement of the main shaft.

Have you checked the cordwise c of g, spanwise c of g and balance of the main blades? Failing that try another manufacture of main blade, like SAB.

What blades are you using?

Ah, you missed Daves earlier post about getting belted in the shin with Torsion blades then. lol.

What blades are you using?

I'm using Torsion GF at the moment and it's the second set of them with the same problem. I've also used the carbons with the same problem. As I said above sometimes it doesn't happen.

The reason I ask is I've had a duff set of Align's recently (the wood core 600 ones) and they cause this very same problem.

I put Radix back on and it cured the problem, but this obviously this may not be the case here.

As Mattie said, try another set of blades as I think you will be surprised.Have you checked the ball links to make sure they are tight in the grips?

I'll give the blades a go. I've checked everything I can think of so it seems like the only thing left

hi dave did you find the cause yet.

[David Drew]

My bet is on blades.

[robgt]

Torsion blades are light and have a rearward C of G which makes them a very active blade, but at the expense of being "tolerant" on head setups.
By this I mean any slop in the linkages, or slightly worn plastic blade grips, will cause problems, where you wouldn't see it so much, or even at all if using more tolerant blades such as Radix.

Of course, it could be something else in the head setup, but do check the linkages to see how much play you might have in there.

Cheers,
Rob

One of the guys in our club has been having problems with blade tracking as well using torsions, he changed them to another set the exact same and it was still out but not quite as bad!

Check, check and check again. If you are satisfied all is OK, then change the blades.

No not yet, hopefully the weekend. I'll let you know

[waveydavey]

I said I would report on what was causing this. To all who suggested the blades then a nice pat on the back. Blades it was. Fitted an new pair of Align D's and the problem is gone. The heli also flys nicer. I thought it was just me, I found the heli pitchy in FF, not anymore as smooth as silk. By the way I had Torsion Gf's on before but the carbons also showed this out of track problem. Cheers

Doubt you have a duff pair Mattie, they all do it, utter crap
