babe wake up new vex hex vid just dropped

[@aydinlutmergp4885]

I did this after seeing a team from my group use it but I just pressed an axle extender into a piece of plastic tube that was drilled to the diameter of the motor spline and fit it on by warming the plastic a little, setting it and letting it cool off which worked great!

[@thunderousvexrobotics7774]

♥️♥️♥️ thanks, we'll cite 606X as the source for this design in the notebook if we end up using it

[@z-powered-nathan]

Wtf why is Ben so better than me at robotics. I made my own 3600 cart with custom polycarb and I decided I should try Ben’s anyway and it works 100x better. This is bs 10/10 design thank you

[@xTigr]

Just made three of these, works great. Thanks!

Does this cause motor burn out for flywheel like where the motor gets rly hot. Currently we r using blue catridge and it burns out rly fast and i was plannjng to find a better sol

[@calebweiler7839]

How would this be coded? I have this set to a blue motor with no gear ratio, and it is not working as fast as it should.

try shoving more zip ties in for a tighter and more secure fit

[@dav.idclips]

what do people mean when they have different rpms how do you change the rpm the motor runs at or does it have to do with how you gear it with the gears? I know about the blue, red, and green ones but those have their set rpms?

[@sripadsirikonda9213]

I did this and put it for one motor. It works great just for the gear on the low strength axle. But when I attached the motor with the gear to the high strength axle which has the flywheel, it doesn’t move. There appears to be no torque on this. How do I fix this?

@@sripadsirikonda9213 there might be a lot of friction on the flywheel shaft. If the low strength shaft works ok for you, then you could probably keep it like that

[@sripadsirikonda9213]

@@606X The thing is I attached the fly wheel to the high strength axle and a 12 high strength gear which connected to a 60 tooth gear that is connected to a low strength axle which is the driven gear. Sorry for that. When I attached that motor to the low strength axle gear, the flywheel does not move which means there is no torque. Should I change the flywheel axle to a low strength axle? Will that fix it? Or should I directly put the motor to the flywheel?

[@606X]

@@sripadsirikonda9213 there is probably lots of friction in the flywheel system, leading to it not having a lot of torque. The best bet is to check alignment of bearing flats, and making sure that all axles spin freely by hand. This will ensure that your 60:12 gear ratio will have enough torque to spin the flywheel.

[@marclindez2179]

Is that legal for under over?

[@sullivan725]

what is the reason behind the bands on the motor? I see everyone doing it but have no idea why.

[@606X]

quickswap. we can change out hot motors with cold ones really quickly instead of waiting for it to cool down

[@brianwei1535]

Can it be used with a high strength axle?

[@gumby5068]

Probably just don’t smash me he insert in although idk don’t plan on trying it lmao

[@rustyrussian8313]

How do I drive the motor, if I input a number of 600+ rpm it just goes to full since it thinks its a blue cart.

[@adambukowski2472]

This violates C. and D. You have to use the official VEX cartridges. E says you can modify the cap tho.

[@606X]

Some gdc q&a responses suggested that this modification was legal. However, there is still some debate. Give this thread a read: www.vexforum.com/t/legality-of-having-a-motor-like-this/103243/48

@@606X Thank you for showing me this.

[@EclipseRoboticsVEXrobotics]

I was wondering did you use bearing flats or a ball bearing. How would I do this with a high strength axle? I do want to use ball bearings, but the motor gets blocked by the ball bearing. Thanks Again! :)

[@606X]

we used bearing flats, not ball bearings. the difference is pretty negligible

Hello, my team has been working on putting together a resource to help less experienced teams, and one of the things we are trying to explain is the different cartridges and ways to alter motor speeds. I am reaching out to ask if you would be ok with us linking this video (and possibly others that do a good job demonstrating topics we are trying to explain) in this resource? I would also be more than happy to share this resource with you to make sure you approve of it's usage.

[@606X]

yep, this is all right! Feel free to link any of the videos on our channel, that's its purpose!

[@fastmanatee8794]

Does it shot well with only 600 rpm. And how does it compare to a regular blue motor

[@hacksolot2]

I designed a 3d printed jig to make it easier to clamp to the vice and drill nicely

[@EXPRESS1TH]

What’s the spec on the high strength shaft spacer

[@cookiezbitz]

How thick are the zip ties used in this video?

[@unlacedecho3108]

Is this type of insert legal still?

[@averagefish7101]

is the low strength shaft holding up with that? also, has 1 motor been sufficient?

[@606X]

this is just a prototype. we haven't had time to develop a fully optimized flywheel unfortunately.

[@lemonjuice7242]

Good work! Can you make a video about endgame expansion system?

[@pocketc0mb]

So what exactly does this do? Does it just make the motor a free spinning motor?

[@606X]

It lets the motor drive a flywheel at 3600 rpm without any external gearing

[@difficult.to.underestimate]

Is this the same flywheel u used at MOA?

[@606X]

Nah it’s different. MoA was 4”, this is 3”

[@jash6503]

Do you guys plan to only use one motor for your flywheel since it's direct? Also since it's on a low strength axle does it work well without any problems? Nice video and thanks for sharing

[@606X]

Yes we were planning on 1m flywheel

[@lizadoesstuff7877]

How is this programmed?

[@liemdonahue1715]

I’m gonna be honest it’s a very good idea but I tried on mine and my motor overheats in a minute, and adding 2 motors also overheats pretty quick

[@ItzMattFPS]

@@zacharyhelms4273 how/where did you get a 7:1 4200 rpm motor? the only ones that we can find are red (100rpm), green (200rpm), and blue (600rpm).

[@mayankpandey139]

what are the benefits of a direct 3600 instead of gearing it up with blue carts other than saving space?

[@mayankpandey139]

also are you still using the PTO on the flywheel now that you have it direct?

[@gumby5068]

Much more efficient friction and power wise, probably spins up faster although I can’t say for sure. 3600 rpm is very convenient because the next highest possible ratio (3600 rpm is somewhere inbetween 5:1 and 6:1) is not possible for the motor to reach very easily but 3600 rpm works. Still don’t know if it’s worth doing this to your poor motors but idk.

[@TurtleMaster7474]

You can flex on the non 3600 people

[@360X_vrc]

There's no real point, how are you going to make a 3 motor flywheel if your motor goes directly into the flywheel. To win you must do 3 motor flywheel like 9364C. Honestly more might be better, 5 motor flywheel 2 motor drive is likely going to be the world's metta.

[@huhrawz]

@@360X_vrc why? u only need 1-2 motors to get discs into the goal. Ur just wasting motors at that point

[@Potatoes9865]

Me and my team tried0 to recreate this design as per your video, but the spacer and axle keeps falling out of the adapter bit, making it very unstable.

[@bertenheimer]

You use collars? Also your spacer might be too thin

[@Chris920B]

How fast can you shoot 3 discs? We are having the issue of too much rpm drop after the second disc gets shot. Any ideas/tips?

[@606X]

use another motor on the flywheel, or increase the weight of the flywheel. both will have less rpm drop

[@turbodog99]

use the hard rubber wheel, not the flex one

[@iAbove]

Have you only attached one Flex wheel?

[@wally7573]

What size spacer did you use in between the insert and the edge of the motor?

[@606X]

[@coltonpayne3788]

"the stiffer the better" mmm yes the words of a wise one indeed.

[@brandonlei3616]

Yw for the spacer in motor cap idea :)

[@reeton3155]

is it better with rubber bands instead of screws?

[@RockyLeong]

no, just way more easier and faster to swap cartridges

[@cuongcjnguyen4405]

is the green motor or the red motor going to work with this trick?

[@606X]

the trick is that it doesn't use any color of cartridge, it uses the direct RPM of the motor without any cartridge gearing it down.

[@229member]

What rpm does the motor get too when spinning your flywheel? (The stats of the motor on the brain screen)

[@606X]

600 (6:1 cart setting). It varies between 585-600 but pretty much stays at 600.

[@jennygo5417]

What’s the advantage of using this mech instead of the vex blue cartridge?

[@rhettmaner396]

It saves gear space

[@paulbunyan3drc251]

Also has less friction due to no Cartridge and no gear box

[@HIVSuperSpreader]

You dont need a whole gear

[@seanyeow6726]

Ben, how would you do make it with a HS axel? I worried the LS axel will bend on the fast spinning flywheel
