Hi guys, i have the ar7300bx on my blade 450x, i played with my gyro on my transmitter but i can not get the WAG out of my tail, what is it that im doing wrong?

Hi Dustin, have you set it up correctly on the AR7300BX? Lee has a good video on correction direction:)

Dustin...this is very important. You need to be very sure that your helicopter is "mechanically" setup, too. After setting up your flight controller, if you still have a wag, I would be thinking that your tail control rod isn't adjusted properly. Set your transmitter to Rate Mode and try to hover your helicopter. Since you can't adjust the length of your control rod, you'll need to slide your tail servo either forwards or backwards, in small increments (1/8" or less). Then try to hover again. If the wag gets worse, slide the tail servo the other direction.

Firstly, is it a fast wag, or slow?
If slow, then these are some things to check.

There are a number of reasons this could happen.
1) Mechanical
Test the mechanical movement of the tail system, to check for binding (stickiness), or Play (slop).
This can be done by removing the link from the servo arm, and manually pushing the rod, to check its smooth.

Then with servo reconnected, take the tail blades and wiggle them, without the servo moving to check for any movement (slop)
Slop will show up in the blade grip links, the tail pitch slider arms, the ball links on the control arm.

Also if its a cheap servo, it could have slop in the gear chain, or bad centring. allowing the blades to move subtly of there own accord.
Wiggle the servo arm, to check for slop. Then with your radio, move the rudder stick, and check if the arm returns to the exact same point every time. (This will have to be done in rate mode)

If all these are ok, then you can move on to electronic set up.

my tail blades are chiped, could that cause a tail wag?

If anyhting it will cause a vibration. That vibration could be picked up in the 7300. Those vibrations would be high kHz range. I an not sure how that would effect the gyro if at all.

tail blades are cheap, Dustin. Just replace them.

Diffidently change the tail blades but don't mix match them. One time, even being the same brand name and color tail blades doesn't mean their similar. Balance tail blade also. I didn't, and a bad vibration occurred and didn't realize it til test flight time. Just an Idea!
