Tail Rotor Basics Part 2 - Gyro Gain

[@lashawnrobinson6662]

Very good video and instructions. This video just help me get my 550E off the ground for the first time after almost a month of setup headaches. Thanks!

[@boldger13]

Thank you for that enormous amount of great information! I love your channel and purchase everything from you when I need it. I will always continue to support your cheese habit! Keep it up!

[@tjtj3829]

Thanks I purchased a T-Rex 500 electric used the original yellow one I've flown it a few times after fixing it up this will definitely help me fine tune it😊👍

Hey Ron i just want to let you know that i think its a bummer your going to retire and that you will be missed a lot but at least we still have your good ol trusty videos to refer to for help your the man Ron and you helped me when i got stuck on something when i got into this dam addicting hobby and i still am learning a lot of stuff from you so i will say thank you Ron you are a life saver and a dam good teacher i haveint had to call you yet but im sure there will be that one problem that requires your expertise over the phone so until then try to enjoy your early retirement before you go to that great big hanger in the sky. sincerely Ron M.

I am amazed! I'd be lucky to have you to learn from first hand as I am a childish rookie who still can't get his new used Falcon 400 3D off the ground! Didn't understand the gyro like I now do. I will be watching as much as possible and thanks for taking the time to help us out!

Hi Ron. I have the same problem at 3:35, imbalance in the tail of the helicopter. Please Help

[@3dwardcpr-cellphonerecordi537]

Good day Ron. I just got a 360cfx from a friend who got tired fixing. When i spool up it turns to one side. When I counter it once it starts to turn that side. So its like the tail slider is sticking to the last input. Please help me troubleshoot. Thanks!

[@laurenellinger8590]

Do you help folks troubleshoot their heli? After watching your video, I'm still having issues setting up my gyro and tail rotor.

[@wcwickedclown]

drift is also caused by gyro failing to initialize unplug and replug in the helicopter lipo

[@1701_FyldeFlyer]

Hi Ron. Good vid! I have an align gp780 in a TRex 600 ESP and XG8 radio. The gain set via Aux 2. All gyro and servos senses are correct but, I have to keep correcting the tail in both normal and heading hold mode. The gain is set to 70% in heading hold and 45% in normal. What's wrong? The TRex is set up as per instructions. Give Mickey a little cheese from me :)

[@antdx316]

I was trying to fly my heli w/o even noticing I have to set the gyro values on the AR7300BX. I was getting 1mm movement and it kept spinnning regardless of what I was doing. Luckily I have the trainers on the 450 and I didn't bother taking off! I added some gain and holy shit I get like 100x more travel. I will try it tomorrow.

[@williamgaines6356]

Hello Ron I was setting up rate mode and heading hold on my flybarless gyro and the values i entered were 75% heading hold and -30 rate mode on my spektrum Dx7. when I tried to connect my Spektrum AR8000 Satallite reciever it would bind properly but my gyro wouldn't initialize properly. I am using a beastx gyro too. Why is happening? I spent close to a 100 dollars on this Satallite receiver and it wont initialize my gyro properly? Why?

[@Nykkytta]

Merry Christmas and Hoppy new year Ron.

[@lpcthug]

Hello, I put my helicopter to 30% gyro in rate mode and mechanical setup with servo horn at 90 and a little bit of left rudder like you say to do in the video but my helicopter (blade 300x) kept going left so I kept moving the slider more and more over to the left it is now to the point where it is almost 3/4 of the way to the left end point! and still drifting left but not quite as bad. I used to setup the tail with servo horn at 90 and tail slider at 90 it worked pretty good only blew out on really hard moves. Should I try to setup the rest in heading hold like this or go back to what I was doing with 90 degrees?

[@valderja]

Great tips. Thanks.

[@jamesmorfison2008]

Hello Mr RON ,THIS IS JJ IN MONTGOMERY ALABAMA .I'M GOING BACK OVER YOUR VIDEO'S ON THE GY401 SET UP ,THIS MIGHT BE A DUMB QUESTION ,BUT IN YOUR #2 SET UP OR PART 2 ON THE GY401 GYRO YOU HAVE THE GYRO SITTING ON THE TABLE AND YOUR MOVING THE GYRO TO THE LEFT AND RIGHT WITH YOUR HAND, THE QUESTION I HAVE "SHOULD THE GYRO BE MOUNTED ON THE HELICOPTER FRAME IN THE RELATION TO THE WAY YOU HAVE IT SITTING ON THE TABLE IN YOUR demonstration in part two of the video " ? OR DOES IT MATTER IF IT'S FACING THE OPPOSITE DIRECTION ,MINE IS MOUNTED WITH THE WIRES COMING OUT OF THE REAR ,THAT'S IF YOU'RE BEHIND THE HELICOPTER ,STANDING BEHIND THE HELICOPTER THE NAME FUTABA IS RIGHT SIDE UP ,OR DOES IT MAKE ANY DIFFERENCE? JUST CURIOUS. JJM IN MONTGOMERY ALABAMA SENT

[@ronlund1953]

It can be mounted in any orientation as long as the base is parallel to the tailboom. If it is upside down, you might have to reverse the gyro using the microswitch on the gyro.

[@jamesmorfison2008]

Thanks for the answer MR RON JJM IN MONTGOMERY ALABAMA SENT CLASS A

[@kdsvelasco]

Nice video, thanks you

[@drummerdad80]

how do you hook pitch and throttle both to the left stick on the reciever

[@ronlund1953]

It depends on the radio transmitter type, model and brand. All "helicopter" radios mix pitch and throttle in the firmware. So, in the manual for your transmitter will be a section on channel assignments. Typically, channel 6 on the receiver is pitch and channel 1 or 3 is throttle. I would suggest searching for your transmitter model number and the word "setup" here on KZbin. Good luck, Ron

[@drummerdad80]

Ron Lund thanks i have an older jr transmitter it does not ccpm so i need to buy a different one

[@ronlund1953]

If you have a local hobby shop with some people that are knowledgeable about rc helicopters, that would be the place to start. If not, Amain Hobbies would be able to help.

[@pierreh9373]

I’m currently working on a Roban 800 size EC 135 (4 rotor blades and 7 tail blades). The tail travel on this helicopter is very light. Having a hard time setting my throttle curve due to this issue. I was attempting to fly at a flat throttle curve of 75%, but the torque from the main rotor was too much for the naza in Heading Hold and rate mode. Is it safe to attempt to fly with a 50/60 % throttle curve being that the tail seems to hold there. If not, can you share a pitch and throttle curve that I may want to attempt?

[@ronlund1953]

Pierre, I know nothing about the Naza, but let me ask you if you can get anymore pitch out of the tail blades if you raise the gain in both Heading hold and Rate modes.

[@pierreh9373]

No. There is no more travel on these blades. Any further will cause binding

[@ronlund1953]

@@pierreh9373 Are you using the recommended 750mm main blades?

[@pierreh9373]

Yes. I’m not using all stock components. I will do a walk around video tomorrow and post it so you may see what my Setup looks like.

Good video Thanks

[@DutchThackers]

Hey ron. Love your videos, They have taught me a lot!. I recently bought an align gpro unit. I'm having a lot of problems with the rudder gyro. The cyclic is very stable and will hover hands off but when I try to yaw right it snaps to the left first then right. Very strange . It yaws left correctly. The other problem. Is that when you yaw it keeps rubberbanding back to it's original position like it is locked into that heading. I have reduced gains significanytly but nothing changes. Any thoughts?

[@Rotors-showCoUk2014]

Scott Thackrey​ what tail servo are you using? Had issues with the align servo with gpro on the 500L dominator its a lot better with a 9257/full size servo

[@DutchThackers]

Hi there, I was using a ds515 but I have now swapped this out for a spare ds520. They are both align servos. it's strange, the heli flew normally with the 3gx.

[@Rotors-showCoUk2014]

Scott Thackrey what model is this on a 500?

[@DutchThackers]

Yeah a trex 500 pro that was converted to flybarless with 4 blade head. Thanks for your help. Really appreciate it.

[@Rotors-showCoUk2014]

Some gyros are better with bad servos than others. Mine got a lot better with a full size servo. Its a simple mod to the frames to do it

[@pierreh9373]

Any reason why my tail will drift back to center in Heading hold mode?

[@ronlund1953]

It sounds like the heading hold gain isn't high enough. As I said before, I know nothing about the Naza, but all heading hold gyros have a way to set the gain in rate mode and heading hold mode. Have you verified the gain? Have you tried setting it to 100% just to see how it reacts (as shown in the video). I would suggest doing that in both heading hold and rate mode. At about 2:06 in the video you will see this. Please tell me what transmitter and which model Naza you are using.

[@pierreh9373]

Hey Rob. So I’m using a flysky FS-i10 radio with cyclic Align DS820M and a Naza H. I did what you told me to do, the only difference is, when I’m in heading hold mode after a few seconds, my Servo drifts back to center. Also, within my transmitter, I have to move the slider negative for rate mode, and positive for Heading hold mode. I actually posted a video so you may know what I’m talking about. Please, if you can, can you view it and get back to Me. Thank you. kzbin.info/www/bejne/g2KTnaZ3bq-Lmsk

[@ronlund1953]

@@pierreh9373 Have you flown this helicopter? What it does on a coffee table tells you hardly anything. You have components that I am not familiar with, which is why I made this video. Please watch it again from the beginning with determination to get what I am saying. I think you will find your answers there. FYI. I did watch your video and your model is beautiful. I cringe when I see you spooling it up like that. Be careful please.

[@pierreh9373]

Ok Ron, flew it, and kept adjusting the gains, and it seems that my problem is a software error. I therefore purchased a Demon Cortex which works beautifully.

[@rmiklosh]

Thanks for the video. I got a question. How come, when I turn gyro sens to 70% (for instance), and move the rudder stick, for example, to the left and then back to the center, the tail blades stay in left position (do not return to the center). Same goes for right direction. But when I decrease gyro sens to 30%, the blades return to the center with the rudder stick. Is it normal?

[@ronlund1953]

That is totally normal. Depending on how your transmitter is setup and what brand it is, you are probably going from heading hold mode to rate mode. So maybe 0 - 50% is rate mode and 50 - 100% is heading hold mode. If your gyro has an indicator that shows whether it is in heading hold mode, watch it when you change the rate and see where it switches over. Good luck.
