Guys....I'm getting bummed out!

[Chris20]

I can't get my 450 sport dialed in. The other day I had minor tail wag. HH is at 60.5%. I replaced the tail slider on the shaft and tightened everything up on the backend. Today, at mid stick, I had not wag...but more of a hard kick. I tried playing with settings and made sure everything wasn't too tight on the tail. Still wag. Then on the 4th spool up the elevator servo defaulted all the way down and the heli tipped sideways. It didn't break anything but scared me. I took the servo apart when I got home and I don't see any damaged teeth. I'm using the Hitech 65hb's. Put it all back together and it's working but I don't know if I really want to use it like that. My 2 questions are should I upgrade the gyro? It's the stock Align gyro and I have never been able to get it to hold perfect even with the Futaba 9257 servo. I've seen quite a few Quarks, Solid G, and numerous other ones for sale in the classifieds. Someone has the Solid G setup for %50. Is and upgrade actually worth it? Also should I try and use that servo or should I buy a new one?

I would replace gyro with a quark you will be much happier

Spartans are cheap used and have top performance

[satgod]

just pull the head, get you a fbl head for about 35.00

and get you a fbl controller

problem solved

the spartan gyro would do it but if your going to spend 65-75.00 why not just go fbl

[Chris20]

And that was my other thought. Ive seen just the 3g for sale around $50 will that do? Or should i get a 3gx?

I dont know about Aligns gyro, never had any of them but I think they should be quite reliable. But did you ever think about ballbearings? If I were you I would start taking a look at tail grips bearing, then tail housing bearings and also front pulley bearings. Sometime I got frustrated and sad about a tail problem like that, at that time when a futaba 401 was about $150.00... All the time I though it was the 9257 servo or the gyro but after few weeks I dont remember why, I found it was a tail grip bearing... All because I use to clean tail blades with windex and some of them maybe removed all the oil or something like that from the bearing. When I removed the tailgrips screw, the bearing came out in few parts. I changed it and then the the heli worked perfectly.
The same hapened also with the front pulley bearings. It is maybe a lot of work to find out wich one is the jammed but to me it sound to me like a mechanical problem.

In about four years I have lost only two gyros and they simply get uncapable to fly the heli.

Good luck!

if you go flybarless the only two systems i cab think of that perform reliably are

beast x

or Vbar

stay away from align 3g or 3gx becasue their hit and miss.

if you go flybarless dont go cheap or you will have same problem as you do know where you are alays chasing niggling problems

[Chris20]

My 65hb's have only about 10 flights on them. Can I put 1 new 65MG on ther elevator side with the others being a hb? I have one extra MG that is brand new sitting around.

Thanks
Chris

I personally agree with dl5973 although I do know a guy that swears by 3g with the silicon mod, says it flys as good as 3gx and its all he buys because he gets them for 40-50.00. I personally have not flow 3g with or without the silicon mod. I have flown 3gx and it works but it is hit and miss on dependability.
Beast-X I almost never hear a complaint about and V-bar is vbar you cant go wrong
they cost more and that may not be fore you because of cost and we all have our limits with the wallet.

so if you want to go fbl get the tarot head. the link I posted in this thread is from a U.S. supplier so you wont wait weeks for it. Its a clone of the KDE head and it flies nice, its what I have on my 450pro

for the fbl unit if you want to save money try the 3g unit for 40-50.00 it will fly, I would do the silicon mod if you are mechanically able to take the unit apart and do it
it solves the problem the 3g unit had with vibration.

Or buy you a tarot or copterX unit but you will wait weeks for it unless you get one from the classifieds here.

I know a guy that swears copterX is great and even put one on his 600efl.
That says alot to me considering its a 45.00 fbl controller and a 1000.00 heli

Yes thatll work. I use ds410m on two positions and ds410 on the elevator . Just cause I didn't have a third "m"... Servos guts circuit and power torque are all same just the gears are different.

Also. Did you set your align gyro to analog mode for this servo? It is an analog servo (if you don't know that)

Another thing, this servo is definitely strong enough but not at all fast enough for the tail. Yeas it shouldn't have a kick, wag is understandable.. But get a better servo first Buddy. A faster one I mean.

I know people troll about align every day. I am using ds520 on my 450 but that's because it a pro frame as I can. You said you a have sport so you need a 450 size servo only. Ds420 is great... Fast.. You might get it cheap in classifieds here .. I used the gp780 for a year without a single glitch. Doing fff loops rolls and all. That's all I could do till then.

Before you go upgrading the Gyro, upgrade your servo to a digital fast servo.

Now as far as FBL is concerned , this servi ain't gonna be good enough on the tail on FBL either. So you'll end up changing that anywaz. Hey I use tarot FBL head and zyx gyro on my 450 AND my 600 nitro. I love the zyx!

But it's not something that you NEED. You can very well get away with a fast digital servo worth 30-35 bucks, and ten of you wanna go FBL, the more power to you. !!

Hope I could help

Pro head will fit the sport perfectly fine.

I don't have these on the tail. I have a Futaba 9257 on the tail. I do however use the 5.1v step down on it too. Should I use the regulator or remove it?

Ohh ok. Then that all rant is useless.. Lol

Regulator i think is not needed, but I would have someone confirm that. I think your servo would be just fine connecting to the Rx straight up. Read the specs... I never used a regulator but then I never used that servo on my 450 either.

[satgod]

if you use a 9257 u can run your bec at 5v and you dont need the step down
but if your run your bec at 6v you need the step down on the 9257 or you will burn it up

The other thing that I just discovered about the GP780 is that you need to set it up in rate mode first. I replaced the tail servo for a Hitec HS5084Mg and I had wag issues as well. I went back through put the training gear back on and set up for no tail drift on rate mode then switched to HH. I am now running 70% on the gyro menu on my DX7 and I could go higher. The tail is holding great so far. I would try setting it up in rate and then switch over and see how you make out.

I think thats usefull...

[satgod]

if I remember right you have to set it up in rate mode then goto hh mode
all the settings will still be there but rate mode will let you adjust travel correctly on the high and low side where as hh wont
