Ok guys,

Here are the final 3 sections of this thread.

5. Adjusting the gyro.
6. Performance modifications
7. Extreme Modifications.

There is still a lot more info in the next three sections. Whoooooooo...sighing.

Adjusting the Gyro

Adjusting the gyro is one of the simplest tasks, but also requires a bit of trial and error. Most new heli pilots have a hard time with this, mainly because they dont know what they are looking for. Well.....thats where this thread comes in. We are going to go step-by-step on how to adjust your gyro, and get it nailed dead on.

First take a look at your gyro. There are two "pots" or adjustments on the side of the 4-in-1 box.
If you look closely, one is labled "Gain" and the other is "Proportional"

Gain is just a fancy word for sensitivity. This pot adjusts how sensitive the gyro is to the movement of the tail. You can set the gyro from NO sensitivity to EXTREMELY HIGH sensitivity.

At its lowest setting, the gyro will turn off, and offer NO corrective inputs to the tail motor. This is not recommended because you will have to manually fly the tail of the helicopter during flight.

At its highest setting the gyro will "overcorrect" because its super sensitive. This results in the tail rapidly wagging back and forth as it searches for center, but cant seem to lock on because its overcontrolling the tail.

Ideally we want the gyro set so that it "locks" onto center and does not allow the tail to move.

The second pot is the "proportional" pot. This pot adjusts the tail so that it is not overcorrecting in one direction or the other. And makes the tail rotor "proportional" to the torque of the main rotor.

For this section, it is required that the heli is powered up, so please be aware that the heli will be live, and you should be aware of safety precautions. Always stay out of the way of spinning rotor blades, as they can cause bodily injury or death.

Start off by plugging everything in as if you were preparing to fly the helicopter.

Center all trims on the transmitter, except the throttle trim which should be all the way up.
Increase throttle until the helicopter becomes light on the skids.

Now let go of the sticks.(you should NOT be airborne at this point)
Memorize which way the tail went. Now power it down.

Lets assume that the helicopter started yawing to the right. (nose right, tail left). This means that the helicopter requires left "proportional" pot adjustment.

Open your manual to page 14 - Tail Rotor Proportional Mix Trimmer Pot Description and Adjustment.

According to the manual you will need to turn the pot counterclockwise (towards the - minus symbol) to correct this.

Im going to give you a very simple thing I want you to memorize.
Turn towards minus = tail RPM slower
Turn towards plus = tail RPM faster.

So your asking what's this for?

Well, anytime the tail rotor spins faster, it turns the heli to the right. If it spins slower, it turns to the left. Now you know which way to adjust the pot in a instant....without referring to the manual.

Here's the tricky part.

You remembered which way the tail moved right? Did you remember how fast it moved.
If it moved very fast, it will require more adjustment than if it just moved slowly.

The pots on the gyro are very sensitive. A little tiny adjustment will do alot. So dont overdo it.

Now turn the gyro proportional pot a little in the direction you need.

Now power it back up and get it light on the skids.

Release all the sticks...

Did it stay centered, or did it still move right....or did it change directions.

If it stayed centered....CONGRADULATIONS. Your done with proportional adjustments.
If it still moved right....turn the proportional counterclockwise a tad more until it stays centered.
If it moved left, you turned the pot too much. Back it off a little.

Once you think youve got it all adjusted...Pop the heli up into a hover.
If the heli still exhibits a STRONG turn...adjust the proportional pot a little more.
If the heli just very slowly turns....this can be corrected by the trims on the transmitter.

The more time you spend and the more precise you get this, the better the heli will fly.
