the hex screws are weights, you can take them off for even more cyclic response. but with all the screws on, the cyclic response is extremely fast!!!! but you can remove some of the weight and get even faster response but less stable
I am not selling the flybar, i didn't think i could bring it to market for less than what they originally sold for, which was $29.99. but I did receive permission from Matt of Ballistic Technology to copy it and make the file available to anyone that wanted it.
some talented guys on a US forum created the dxf file which can be ported to g-code so it can be cut on a machine. but you can also print the file out and you will have a full sized template to cut your own. be careful if you use carbon fiber and cut it yourself, you do not want to inhale the carbon fiber dust.
i don't know how to upload a file on this site, it will be posted on my dedicated fc site or you can pm me your email and i'll email the file to you
i will not post my site url here, you can easily google my screen name
