Hey guys I am completely stumped by this issue that I am having. Let me start by saying that I was not having any issues until I changed from CY blades to Align blades and changed the clutch.

Ok- so here is the issue as I start input throttle I get some torque steer to the left, which is normal. However when normally the tail would have the RPM to stabilize the turn left now it keeps what I call torque steering to the left.

I can see that the gyro is compensating 100%(even 100% manual input) however its not enough. Its like the tail doesn’t have the power to correct the torque steer. I will say this its not out of control or anything but enough that I will not take off. Let me know what you guys think.

is this something that happened after a wreck?
because it really doesn't sound like it would happen normally with just changing blades.
may want to check your tail trim on your transmitter and make sure you did not bump it.

check the simple things first like the transmitter the machine and if you still don't find it check the servo make sure it is still moving smoothly when unpowered. and when the servo is powered on make sure it doesn't do any twitchy type movements or sluggish or weak. after that may be gyro.

in my mind it doesn't sound like the problems coming from the blades unless your getting a bunch of vibration from the blades. then you may have just got a bad set blades.

Yea, its very strange but no wreck. the problem that I have in my mind is that if I am compensating 100% and servo and tail blades respond accordingly why is will not correct the problem...

No... Eveything is smooth with minimal vibrations. Could it have something to do with the FBL sys?

maybe. may just have to try and hover it and be ready to kill the throttle. maybe just tripping you out.

Possibly, It acts like the tail gear ratio isnt adequate but of course nothing has changed...

the only thing is if your spooling it up and it turns a little the gyro maybe trying to put it back and if your holding the heli down with neg pitch you may be not letting it go back were the gyro wants to put it. maybe try and put it close to zero pitch if you haven't already and see if that helps. with out being there I can only guess whats going on. maybe have to check your gyro setup again make sure nothings changed.

hope you get if figured out.

When you changed the clutch did you have the boom off? If so you might have not got the tail set back in the same place. you might need more right rudder set with the mechanics.

Check to see if there is a small signal going to the direction of the turn. It could be from a trim change in the Tx, or the FBL unit adjustments.

I think your new blades have more drag and ar requireing more tail input to neutralise this torque.

reajust your tail trim in Rate mode and that will be your new mechanical neutral. I wold translate this trim into mechanical ajustment. It should fix he situation.

All blades don't drag the same.

You could also hang some longer tail blades if you need a little more authority back there... after you ensure your setup is correct.

Guys I have figured it out and I'm almost to embarrassed to say what it but what the heck.

Ok when I reinstalled the main shaft I used the incorrect hole for main blade block. What that caused was positive pitch across spectrum which In turn bogged motor not allowing tail to get up to speed to stabilize.

When I corrected this it business as usual.

Thanks for all the help.

Glad you got it figured out. We've all had similar things happen.

Make sure that the tail is not loose on the hub and spinning as you give power, And check to see if you can turn tail blades while holding mains. If so there is a gear problem. Your new clutch could also be slipping causing the tail to slow along with mains.
