going "forwards" with 45* mecanums, you'll go at about 50%, 90*, or omnis will get you 100%, and 30* will be less forward movement than 45*, and 60 will get you more than 45.
oh and the 50% is not correct if i remember a thread from looong ago

i read a pdf i found on Google a long time ago about actively adjustable roller angle mecanumwheels. it was basically like a collective pitch actuator inside the hub of the wheel that let you change the angle of the rollers from 45* to 0*. mostly for efficiency in forward motion and also some Redneck gear reduction while moving sideways. much like the rotor blades of a helicopter or an airplane propeller with adjustable pitch

Sorry about the lack of reply. The roller are 3/8 id gas tubing from autozone with a sheet of brass foil from Joann fabrics on the inside to act as bushings. i am not sure about the angle of the wheels. Due to the stock vex plate design It was hard getting a consistent angle so its whatever angle it happens to be. While this is the only finished one currently those of you going to Ruckus off season comp will get to view them in action on my vex bot. Thankyou for the support.
