Please read my tail tale...

[propertytrader]

My tail, or rather my 600N Sport "Belt" tail is waggin (not hugely) from the first flight (had about 13+- now). Followed Mr Bob's vids on 611 Gyro and tail setup, and she's holding in Normal mode with minimal or almost no drift. Gain readout on both Normal and AVCS mode 34% - 35%. Equal servo travel, with Acc. Delay at 10% and Dec Delay at 40%. Set to 3D on gyro for smoother response.

... Can't resolve my wag and might this be the problem, please read further....

Still waiting for my Radix 600's to arrive and currently using a Raptor 50 Titan's woodies. Yes I know... the manual states not to use any woodies at all. but hence, I'm just hovering "for the love of heli's!!!" My friend that gave them to me had no problems at all with them on his Raptor Titan 50.

Still not sure how the belt tension must be on the 600n sport, currently quite stiff, can that be the cause of the small wag. Can it be the Batman like Tail Blades?

I saw GY401's holding better than my 611. Waiting for the weather to clear up to test with reduced tension. :arggg:


Pleez help!!!!

Well when I received my 600n it was already built hanging from the celing of a habby shop NEW .The belt was quite lose I even asked about it and they said it likes it that way . But as I have flown a bit I have had to ad some tension to it because it was rediculouly lose and once I tightened it the tail seemed a bit my stable and less jerky SO I would say find a happy medium with it that is not to tight because it will burn out the tail bearing s in Flight and cause you to crash. But to lose is not good either. My belt tension is where I can push it gently over to toch the otherside of the belt .You will feel when it is to tight or to lose if you mess with it a bit.Just remeber you don't want it to slip.But you don't want it to tight.
Static electricity is also an issue if you are running a Carbon Fiber Boom tube,,,,,Especilly Danger Desgin issue on the Trex500 ( A Static Dischrage so bad it knocks it out of flight ) Also keep an eye on the Brass slide collar of the Tail pitch asmbly it comes un screwed in flight .Its right handed threads should be reversed to stop this from happening .

belt should be able to be moved about 1/4" anything more than that and its too loose.

It takes ALOT of gain to get a 611 gyro an servo combo to cause wag. What is your limit A and B setting on the gyro? They should be between 115-120 and exactly the same on both sides.

Make sure their is absolutely no binding in the tail rotor slider, pushrod, belcrank, and no notchyness in the tail rotor blade grips.

There could be a few causes for the wag, if you are running woodie main blades then I'd guess (hpoe!) you are also running a fairly low headspeed, this resulting in reduced tail power which could contribute. There could also be binding on the thrust races in the tail blade grips, if you do a search you should find more info on this. I cured the tail thrust race issue by fitting a Quick UK tail assembly, this stopped the wag and allowed me to increase gyro gain.

I wouldn't have thought that a tight tail belt would cause wag but it will increase drag and affect autos, Tim's method sound good.

just to correct some info. I have never read on here an issue about Static Electricity problems on the 600N. i'm not saying their aren't any, just saying i've never seen anything posted about it in the 600N section.

The only Static issues I know or have experienced have been on my 450 's and the 500 ep especially with a Carbon fiber Boom tube belt drive set up.It will knock it right out of control . I tried using anti static spray it seemed to help a bit but never really eliminated the problem.I am not sure why any Heli manufactures OR Plane have addressed this issue it is very real to Aviation has been dealt with on a full scale level for years ,SO why not RC aircraft too. I know evrey Full scale Heli's or Airplane have Static DIscharge cables running thru them to its wing tips or to the tail rotor housing or some other place on the Pod. A bit like a Lightning Rod if you will and the are very effective at what they do. The Drier the air the More Static the more humid it is the less . But you also have other conditions which can cause static as well. Say a Powered System with magnet slots of wires and a little fast spinning motor ( Electric Heli 's Mechanical enviroment of operation) I did not know it at first but in some way's the little electrics are their own worst enemy for self distruction.
Since I have started flying my Nitro every day I hardly ever mess with The litttle guys any more:dontknowNow I have more money for nitro .Seems to me no matter how well you build and take care of your little electrics something always happens making it crash or the wind .They are a money pit Foucused at us a a consumer cash source of endless amounts:wow2::...:need I say more. ALign is not really your Friend
Sorry did not mean to sound off like that but s its all true at least from my experience so far. I do intend to keep flying heli's ANd yes I will probly go right out and buy the Trex700N when it comes out .:happyd Have fun Safe Flying to you 'all
Heli Up:whip

you said it yourself, you haven't experienced any static issues w/ the nitro, so mentioning it has no merit. I've never seen any static issues w/ the 450's either. And i've got experience w/ a 500 that has had no static issues from day one when i built it, set it up and flew it.

anyways, i didn't want to start an entire flood of "are their really static issues w the 600N" posts b/c of one statement.

Thank you for all the replies to my post
I've reduced the belt tension drastically as it was quite stiff and will test it later this week.
