HELP WITH VEX

[AlexanderTheOK]

If you mean VEX EDR then you will find better help on the vexforums.

You will also get more help if you include more information in your post, such as what you are planning, how the gearing is set up, and why the speed needs to be increased. Currently your post is extremely vague and unlikely to garner much useful information.

Have you thought of doing 2 or more reductions to get the higher speed?
You probably want to figure out a gear box using available VEX gears to bring the speed up to whatever you need. Just remember you will be trading speed for torque and the gear box may have more friction than you want so you may not be able to get really high speeds after you apply a load to this system.

Good luck
