Horizonhobby.com How To - Setup your Head Lock Gyro the easy way

Headlock Gyros have been the main thing that makes high performance helicopters controllable by the average modeler. I have worked for a long time and suffered through a number of frustrating Gyro setups before a friend showed me a simple way to have a headlock gyro "locked" from the first liftoff. You will see that it is different from most instruction manuals. Basically the idea is that we do not need the "Gain Mode" in heli flight. Except for the bench mechanical setup session we will not use the gain mode thereafter. The Head Lock function is by far the most important for your helicopter and with this setup you can count on your heli tail rotor being in trim from the first lift off. Our video will outline the steps. They are included below for your reference.

Watch this video, and then try it on your own collective pitch heli. It really is easy.



First I'll assume you have your main controls setup in your Transmitter.

In the transmitter:
1) Make sure you have the rudder trim tab and sub trim functions set to "0".
2) Set the TX rudder travel to 100%
3) If you use the Retract Switch or Aux 2 lever to switch Gyro modes set the Headlock position to about +60% (nothing critical here we will fine tune later) and rate mode to -30% (not critical)
4) At this point set the TX gyro lever in the Rate Mode position (for setup only!)
In the helicopter:
5) Fix the servo output arm such that it is at 90 degrees to the servo
6) I assume you have mounted the gyro and checked the servo response direction (left and right commands from the TX) as well as the Gyro response direction (it should go left when the nose goes right).
7) With your tail rotor servo connected make mechanical adjustments such that the tail slider is in the center of its travel (equal movement left and right).
8) Using the gyro "Limit" function, adjust the travel of the servo such that full left rudder does not bottom out, then go over and see that the full right does not bottom out. Change the Gyro limit until you have the setting correct.

Believe it or not you are done. When you are ready to fly set the Gyro switch to the Head Lock position and turn on the TX then power up the helicopter. Allow the gyro and heli to sit perfectly still during the initialization process. When everything is ready to go you can lift off.

[newbflyer101]

this video is incomplete. nice attempt tho. Lots of small details and other settings he skipped.

[HorizonRCdotCom]

@newbflyer101 Not very much left out, try it. If you open the link below the video player there is a complete step by step. What is it you think we left out?

[superfish99]

just for a small correction on your title, your are missing 1 letters "u" after the Setup you.... sorry to bother and i will change my settings on the 401 gyro on my blade 400 that has a small tail wag... thanks! have a nice day!

[HorizonRCdotCom]

@superfish99 Thanks Super, was trying to finish this on Friday before I left. re the 401 this setup works fine.

[epoweredrc]

Nice video, Wow I want a job like you have, I love RC have for 22 years. I do not know it all but know lots. Really like HH videos.

[HorizonRCdotCom]

@epoweredrc Thanks epower, yep it is fun and you never quit learning new things. Helicopters have made huge gains in those 22 years haven't they!

[crazythumbs101]

i have a trex 500 with alot of spare parts and 6 batteries for sale. go see my FOR SALE video at crazythumbs101 or search TREX 500ESP for sale.

[TheGamerfromthefutur]

wutz wrong with mines the blades spin but it wont lift up itz a 3d helicopter

[gmodesike]

kinda looked like szabo jr. flying there lol

[prokysoft]

Realy great and usefull video, thanks!!!

@jauchiu

In continuation. First, set the limit from the gyro. Second, push and pull your heli by dragging the head steadily in opposite directions. Three, as you drag and pull your heli, check for binding on the tail rotor. Four, adjust gyro limit accordingly until binding is gone in either direction. Five, grab your TX and move your rudder stick to opposite ends. Six, If the tail rotor binds, adjust your rudder end points until the tail rotor binding is gone.

[spiro9210]

@jauchiu

I know this is late, but I shall explain. adjusting the end points in the TX is for limiting your inputs only i.e to prevent you from binding the tail rotor while pushing the stick left and right. However, the tail servo also receives separate commands from the gyro, and you cannot limit the gyro from the TX...hence you need to limit the gyro from the...thats right...the gyro limit function to prevent the gyro from binding the tail rotor.

[spiro9210]

This video is missing critical important details. ALL NEWBIES, you better make sure that you choose the right tail servo horn as well as the proper positioning of the ball link. If you fail to do this, your tail rotor will bind on both sides and you will not be able to compensate for it with the gyro travel limit function. In short, try to match the same distance of travel from your tail servo with the amount of travel of your tail rotor as much as possible before attempting to limit with gyro

hi guys I got one problem and I cant sort it out. my Gyro is just working find but when I push the throttle up quick then what happen is the head wil turn or spin to one side at the same time with pressing rotaltion. I dont know why. Could you please help me out. but when i push the throttle up slowly i wont do that.

Anyone can help me please. Thanksss

[mrfourtysevenman]

is it a BAD thing to have your tail and main rotor spinning clockwise? i think it is and that might me the root of my problems.
