This is John Adams technical director of Spektrum. The system is much more complex than you describe. There are 3 electronic gyro, roll pitch and yaw and 3 electronic acelleromerers, X,Y,Z axis that updates the bikes position hundreds of time per second. Combing this with the commanded values from the transmitter and some very complex algorithms which took over 3 years to develop. Also keep in mind ther are PID loops for AXIS. This is truly a 6. Axis gyro that has been finely tuned by Gil Losi Jr and Frank R. Through hundreds of hours of testing.
Thank you for the additional insight! I love the bike and by no means am trying to explain the how its programmed, even as an IT guy by trade theres some magic wizardry going on here to me. I am trying to better understand the practical effect the gyro/lean knob has on what it does as far as inputs are concerned while driving. In my tests so far at least on this surface it generally seems that Gyro/Lean knob turned all the way to the right (100%, clockwise) seems to almost remove the gyro input over-rides entirely from the equation. I only see inputs at this setting that are needed to save the bike from crashing onto its side. When I set it to gyro/lean knob all the way to the left (0%, Counterclockwise), the gyro makes lots of input over-rides to tighten up the corner and keep the bike more upright, particularly at lower speeds. I know the gyro takes into account all 3 axis, and I do not yet understand how all 3 axis impact the input over-rides. I also know it functions differently in different ride modes, since in wheelie mode that knob impacts wheelie height/angle. This was tested exclusively in dirt mode. I would love to understand more in depth how different settings impact practical control over the bike though. Would this be something you'd be willing to discuss either here, or in a DM somewhere? (or maybe even an interview for YT?)
@@NHO-RC This is an angle on roll demand system not a rate system. The yaw gyro is a rate gyro while the pitch gyro is a combo of both. Accelerometer data to provide very accurate positioning is critical as well. As the inventor I just hate to see inaccurate information posted. We spent over 3 years on the electronics package to make this work.A patent should be up shortly.
@johnadams3724 - I absolutely don't want to be conveying incorrect information to my viewers. From a practical standpoint in dirt-mode on a flat, low-traction surface I saw the same behavior at different speeds when turning in either direction upon using slo-mo analysis. I looked at probably 3 dozen different slo-mo clips from my filming/testing and all of them exhibited the same practical behavior. I cannot tell in dirt mode if the gryo over-rides throttle input at all. It does not feel like it does it only seems to do steering inputs. I suspect the over-rides would be different on a banked surface, or an incline/decline. I would absolutely love to understand more in-depth what is going on. I cannot however find any documentation on angle on roll demand systems vs rate systems easily online. Would you be willing to do a remote interview to chat about the system a bit more in depth about how this works? Myself and my viewers would love it!
@@NHO-RCThat's pretty dang cool to have the technical director of Spectrum giving you info in your comments, I haven't seen that in anybody's comments, 😁 This technology is far beyond my technical skills but I do understand the gist of it sort of lol 🤣 Fricn awesome job to all the guys that worked on this project 👍🏻
The Gyro is always working. It's adjusting the PID loop when turning the knob. The higher the gains the less it will lean and tighten up the bike which also makes it resistant to outside forces. The lower the gain the looser the bike becomes which is why it will lean over more.
When you counter steer a motorcycle the object is to turn opposite of the way you want to turn to make the bike lean into the turn quickly. Once you are at the lean angel you want you then turn the front into the turn to complete it. The key to good grip is to try not to turn the front wheel at that point.
Seems like throttle, steering and braking all have to be feathered to meet the needs of the corner--just like a real bike. Finding that sweet spot of the gyro with your driving style is key. Thank goodness the gyro control is just a knob on the transmitter. Great video and explanation! This bike is requiring some skill to master just like helicopters and airplanes. Subtle thumbs win. For this reason, the bike is actually a challenge to learn which will make it more satisfying. I have planes, cars, tanks, helicopters etc. I'm always reaching for the more challenging models to control. Can't wait to get one!
Very cool seeing the different views of how the bike handles in different modes - settings, Love to see more of this on different surfaces etc, Very cool, keep it up, I subscribed 👍🏻✌🏻
I really enjoyed this video, I learned a lot from your experiments and experience . Mine finally came so I'm taking in all the information I can . Thank you
Your welcome! I highly recommend checking out my followup video where I learn even more about it. Its does more than I initially thought - ruclips.net/video/eSVt4gKr-Zc/видео.html
Yes but seems to me this is different as the manual of losi more Gyro the bike lean more instead lean less as I can see in your video 😅 low Gyro setting instead lean more and more control awesome video thanks to explain everything
The manual definitely is not clear enough but its so hard to describe without an example like this. Moving the Gyro to "100" (full right) does result in more lean since the bike is willing to let you just fall on your face if you let off the throttle but it seems like you lean more when the gyro is "0" (full left) since the gyro is helping you.
@@NHO-RC the track seems to be a constant job unfortunately haha takes precious rc time away haha 😂 but it’s well worth it atleast my side not much around me for rc racing had to build my own setup.
Ive got some heavy equipment to help with the job and some kids to help out so it shouldnt be too bad. I mostly just need to remember to get some new material in to make the jumps and berms
@@NHO-RC hell yeah buddy I got the kids part but not the equipment. I was pleasantly surprised at how well a yard mower with a wooden pallet and some rocks would work out to get the base set. I say start building buddy will make some killer content
Without watching Ive been curious to different gyro weights or rpm speeds in the future seems to need some adjustment ability... Maybe I'm dead wrong!?
So the flywheel in the frame simply spins at ~22,000RPM at all times, this never changes from what I can tell. They gyro control knob makes the receiver ignore your inputs and steer in a way that will result in the tightest possible turn.
this thing needs space and big jumps.......im talking like a real motox track, madness is probably the closest track we have so far that comes somewhat close
One thing that is a little confusing- when you keep saying 100% gyro, I think you mean full clockwise on the gyro knob, which actually means almost no actual gyro function. Then when you say zero gyro, I think you mean fully counterclockwise on the knob, which is actually full gyro function. It makes it confusing. I think it would be easier for people to understand if you referred to the settings as 100% Dial, 25% Dial, etc, or something similar
You are wrong with the gyro. 100% gyro is 100% assist. 0% gyro is basically pro physics which has no corrections. The right frame is 100% assist the left frame is 0% assist

John can you explain why when you bind a Dx5pro you loose the functionality to Reverse servos and Throttle travel. A explanation would be great.

Once we figure out this baby gonna be more competitive on the track 👍👍👍
For sure. Tuning the surface for gyro and break trim is going to be super critical.

Once you are at the lean angel you want you then turn the front into the turn to complete it. The key to good grip is to try not to turn the front wheel at that point.

Yeah it's all a balancing act! I'm going to keep focusing on one adjustment at a time and hopefully be able to offer a tuning guide in the future

Its quite confusing! Thanks!
great vidéo thank's👍

Sangat membantu

I don't think altering the flywheel on the fly would do much with how long it takes to spin up and down
Does the gyro control knob adjust the mechanical gyro in the frame or the gyro in the receiver
So the flywheel in the frame simply spins at ~22,000RPM at all times, this never changes from what I can tell. They gyro control knob makes the receiver ignore your inputs and steer in a way that will result in the tightest possible turn.
👍💯❤
Thanks!

I don't think that's the case. I think 1/10th is doable if the turns are banked and 1/5 should be totally fine. Just takes practice and tuning.
Anyone done some legit dirt hill climbing with this bike yet? That is the one untapped RC class I would love to see explode.
Ive seem a few 3d printed extended trail arms posted on fb. There's certainly some interest
To bad nobody can get one

I think it would be easier for people to understand if you referred to the settings as 100% Dial, 25% Dial, etc, or something similar
Yes in the future I will do so. I did not fully understand the function until after I shot and reviewed the footage in slow mo
You are wrong with the gyro. 100% gyro is 100% assist. 0% gyro is basically pro physics which has no corrections. The right frame is 100% assist the left frame is 0% assist
At both ends the gyro is assisting you can't turn it off. Check out my second video on it.
