Oh, did you mean that your Heli goes diagonal instead of perpendicularly to the tail for left and right?
I thought you meant the tail turned while giving a lot of collective.
I never figured out how to stop the diagonal cyclic, I think it's because everything was plastic and it would flex too much when the flybar assembly pushed against it.
Do you have the 450X with orignal plastic head?
I would purchase a 450 pro, copterx or align, that's how I solved it.
Oh ok! Yes, the tail will move right when you give a lot of positive, 14 deg of pitch is a lot, so you need a good tail for this.
Grind the tail shaft so that the tail hub can be placed further out, that'll give you more pitch on the tail blades for stopping it from going right. You must increase the travel and gain on the gyro.
The tail belt also needs to be tight enough not to slip.
I have gyro futaba gy401 servo S9257 in clone trex450, and have the same problem in the video 0:14 second. With more throttle the tail move to the Right. Can you fix it? how I fix this problem?
The 401 only auto-compensates to a percentage of the full range of the tail pitch, so the full auto-compensation probably isn't enough.
To get more out of your tail, you can grind the ridge on your tail shaft further out, so the tail hub sits further out on the shaft. You can have the shaft filling the hub about 60% without a problem. I've done this for my trex 450 pro and it has helped the tail hold a lot better.
After increasing the mechanical range, you have to readjust your servo so the slider is centered and the extremes just reach the sides, I would increase the range so that it pushes againt each side, that'll give you more auto-compensation, but may burn out your servo quicker, but that's up to you, only do it of you need more.
Also increase your gyro gain until it wags, then back it off a bit, that should be good.
My helicopter is not that great. It's the plastic version, 450X, you can get the 450 SE V2 with GY401 and 9560 servo on the tail, HS65 servos on cyclic, 35X ESC and 430XL motor for about $650 on ebay. The cost of mine was about $600 because of the servos/motor/esc/gyro, so it's probably best for you to buy it all new off ebay. If you're having problems setting it up, the hobby shops will help you out. Good luck!
I have been tried so many helicopter but not many of them fly like your. I got only to about a feet and then crash most of the time. =(. i was wonder if you sell me your helicopter t-rex everything just without transmitter or reciever. Please reply back Thank you
hi david thank you for your help, is very useful.
But, I think I know what my problem and would like to know your opinion!
In my spektrum tx dx6i in swashmix, I reduced the pitch to 65% and getting to -11 and +12.
I previously had the option swashmix tx and got about 90% and -14 and +14 or maybe -15 and +15.
I think my problem is that. Today it has yet to experience because it is much windy.
What do you think? Could it be?
Regards.

@DavidSunshine867 Hi david, my heli is metal head, Today I change in tx swasplate pitch for less 65% and dont work :(
You says " I thought you meant the tail turned while giving a lot of collective." Yes friend it is my problem in the heli.

@DavidSunshine867 With a lot collective pitch the tail move for the right like the video in 0.14
Please, can you explain again in detail how fix it?

@cfreire31
You're welcome! Let us know how it goes. Let me
know of you run into any problems.
There may be a thread on helifreak for the tail shaft modification too. But it's pretty easy.
Cheers!
