e-Align T-REX 250-450-500-600 > OK I need some info my Rex turns left fine but right isnt so good?

It seems that my heli turns to the left great but it wont turn right verey well at all. Now I understand that this is due to some of the tail pitch is beeing used to counter act the main rotor turning inertia. So if I change from the plastic to the wood main blades does that have an efect on the inertia of the blades? Meaning will there be less inertia of the main wood blades so I can lessen how mutch the tail is having to counter act therefore giving me more ability to turn to the right? sounds reansonable just wondering.

Sounds like your heli is left handed



Sorry, couldn't resist

Space the balls out on the tail pitch slider. I put little nuts (leave that alone) under mine.

Changing to the wooden blades will not make things better. It sounds as if your setup of the tail is not ok. How long servoarm for the tailservo are you using? Basically, when the servo arm is 90 degrees to the tail, the Tail pitch control arm also shall be close to 90 degrees of an angle. This is a very basic setup, but should push you in the right way to find the problem. Do you have full stroke on the tail pitch hub when giving full left or right rudder? If not, endpoint adjustment needs an overhaul. Or perhaps a longer servo arm.

Here is some more info I get full throw both ways everthing seems fine ive monted the ball on the servo in just the right spot. Its just when the tail is already taking up so mutch pitch to counter the main blades dosnt leave mutch for actually turning that one direction. Putting the nuts behind the ball links sounds like a good Idea. If I did that I would get more pitch so that I can turn to the right without effecting my left turning. Thanks for the input.

You will loose a little but you should still have plenty. With the stock setup you get about the same travel left and right (in tail rotor pitch) You have the torque of the blades helping you turn left so this evens things out. There is also an aftermarket shaft that is longer to compensate for this problem.

Increasing the head speed and reducing main blade pitch will help you out if the tail is set up properly. You might also check to be sure that your tail rotor hub is as far out on the shaft as it is supposed to be.

tailspin is dead on. Sounds like something is slipping, (T/R not up to speed) or your head speed is too low.

my head speed us in the lower 2000 range. Isnt the tail hub grub screw supposed to fit int the divet ont he shaft, if so thats where I got it? What should my head speed be Ive read max of 2400 with the wood blades correct?

Most people are running the headspead @2400 or as close to it as possible. Your tail will gain authority by increasing your head speed. But, if you are on the lower end fo the power (400s) you will probably have to mod your tail for good control in forward flight. I find at the lower head speeds I can turn both ways in a hover or real slow forward flight but if you are working it it seems a little weak. You tail shaft is not slipping if you can control it at all. If your belt slips the tail will jerk like you would not believe.

FWIW: I solved this problem by running the ATV at 120% and moving the ball in on the servo arm. Are your ATV settings even in your transmitter?

Solved it thanks

Ok guys thanks for the input but I'm sure I figured it out with your help. So I took of the tail hub to see where the grub screw had maid marks in the groove of the tail shaft. There lies my problem I had it almost all the way in So I moved it over in the groove to the other side towards the end. Now all I have to say is tons of pitch in both directions.

I didnt really think that groove was that wide but I was wrong moving it to the edge of the groove made a huge inprovment.

I just did the same thing. I actually filed a flat on the end of the shaft about 1/16" from the end so I got it out even further than with the original groove. I have not flown it let but I think I got a lot more travel. I was also careful not to make the flat to the end of the shaft and to make the set screw very snug with loctite.

Thanks for the tip!
