    @Unionjackjz1 Looks like you will be taking some W's in Maryland. Do you plan on traveling for competitions this year? Maryland has some states nearby that might be worth competing in.

    Your team should come here to Virginia. We'd be pleased to have you all compete with us in a competition or two.

    Does it have a ratcheting mechanism?

    @FullMetalMentor Very impressive for so early in the season!

    That's because it's a modified Nothing But Net meta bot. Don't get me wrong, I'm not knocking it. They have made good and effective changes and have decided not to reinvent the wheel where they don't have to. But I honestly thought this was a meme video and this was their NbN robot that they had saved (people love having old robots play competitions). When I saw the flipper and that the dimensions of the intake are modified to accommodate the smaller balls this season than NbN, I started laughing because I realized this was serious. Again, nothing wrong with that, I just find it funny that VEX decided to do another shooting game with similarly-sized balls and well... this happened.

    Why would you not start with the most effective launcher from the previous shooting game? In any game that you have to lift you go straight to a dr4b. You can literally say this with any re used design in any game.

    That's exactly what I'm saying. You did a fine job.

    No, Disco is still infinitely better then any flywheel made this season..... so far.

    My team and I were not competing seriously until a few years ago, please tell me why was disco such a good fly wheel? Everyone is saying it I just don’t know why or how it’s different from 60x which looks almost the exact same, sorry if I said anything dumb I am just still pretty unfamiliar with flywheels

    Discobots were the first team to make a single flywheel in this way (Front shooter, Front launcher), or at least an effective one, and did it fairly early in Nothing but Net. They had all season to perfect those robots while anyone that wasnt 2587 or 1104 only had a couple months to replicate what they did in almost a year. Everything about there robots was just tuned more then anyone else's clones and it made a noticeable difference considering they had 3 teams in the worlds finals.

    Actually not true. They werent the 1st.

    https://www.vexforum.com/index.php/14713-8059a-robot-in-1-day-singapore-vex-edition-reveal-more/0

    8059K was actually the 1st that came out with this concept.
    Just that during that time, the focus was on 8059A.

    But if you look closely, you would realise that the basic idea or concept is the same.

    @Zach 929U or at least an effective one

    Not throwing shade but Discos was truly the first version of this style of robot to prove it was superior.
    The fact that the large majority of teams were copying 8059A after this is some more proof. Maybe this did inspire disco though, but im not sure because how many FRC teams have had robots like this in the past.

    @Zach 929U Other than covering the flywheel with rubber bands and putting foam padding on the wheels, what else would you recommend to be able to get a shot similar to your single flywheel. We have friction matting on our hood.
    I also have a question about the specifics of the hood: Is it better to have a large area where the ball is contacting the wheel and have relatively low compression or have a small contact area and have relatively high compression?

    Lastly, when shooting, what is the lowest rpm your flywheel reaches when the ball is going through?

    Thanks,

    I am not disputing that disco had a great robot (or maybe I should say robots... with 3 in the worlds final).
    They had the best flywheels for Nbn.
    In fact, we knew we had no chance of catching disco with a flywheel, and that’s the reason we did a 4-ball catapult.

    And no... 8059a did not invent single flywheel - a fact that we had openly stated during nbn season as well... we had clearly mentioned it was from frc. We were maybe just the 1st to make it work well in Vex that’s all. And I have mentioned it many times in the past as well - there is nothing new under the sun.

    All I am saying is that they were not the 1st to build a front intake and front shooter flywheel. 1st to build a great version of it, yes... but 1st to build this version... I am not so sure.

    The 1st and 2nd question have the same answer: compression. Work to tune the compression that makes your robot shoot at the arc that you want it to shoot at

    The 3rd question would vary amongst flywheels. Some like Zach's have high momentum so they don't lose RPM that easily. Some others lose a ton of RPM after a shot. If you wanted to test yours you could easily make a function to tell you RPM.

  19. @Zach 929U what ratio do you guys have on the flywheel?

    probably 1:15

    I know that my 3rd question would vary among different flywheels and the way they are built. I'm just curious how much theirs decreases so I have an idea of what to set as a target to sort of work towards.
