I am for one very disappointed with the upgrade part that is "supposed" to allow for the mini bike motor to be linked with the standard cim in the kit. one the instructions call for a 8mm id 3x8" long washer and a 1/4" long washer, both of which where not present in the box when the shipment finally arrived. second the 28-toothed MB gear can barley if any slide down on our mini-bike output shaft. i know this seems to be a little over the edge but to me when you purchase a upgrade for a certain part or object the upgrade should
one, be of little ease to install and
second have all of the parts that are needed for the completion of the upgrade. i know Andy mark is a good guy, but my team has no time to waste as i well know every FRC team has no time to waste to try to install an upgrade and not have it work. i have purchased his products before and they always have been of high precision and quality, but this current product is by far our worst product. instead of getting the motors installed in a few hours we have wasted two days trying to make parts for a "part" that is supposed to already work and fit on the mini-bike motor. if Andy mark does read this reply then i highly ask and urge him to look over every product that he sends and makes sure that all of the parts are in the box when it is shipped.
to every one else who has already purchased one of these upgrades i hope and wish that you have better luck than we have.
