 The Kart Kit should be the most basic, so students can see some upgrades very easily to start.  For example, start with just one motor, driving one wheel.  We would hope students could theorize that adding a second motor to the other wheel would be an upgrade.  Then considerations for a different drive altogether (live vs dead axle), maybe a differential, etc.
-(A STEP file, picture and other info will be posted by this weekend.  Frameworks is the company that has helped design the frame with a 50% school discount to build/sell, and we have other sources to share.)
+Here is a link to a Google Drive which contains some frame concepts, budget, and links to suppliers. [[https://drive.google.com/folderview?id=0Bz1uEnTBg46Qa1UyU0pYbTEwZ00&usp=sharing]]

+-02-20 - We updated the folder for our refined model.  It's an 8020 1020 base, and we received a quote from [[http://tslots.com/|tslots.com]] to make it for $187 (including all materials!)  We have ordered one to test out, and if successful we will be raising funds to build a LOT more.  I anticipate 6 students per kit when working in a classroom.
-In short, one uses a VersaFrame (and it's WAY too big, but within PPPRS regs) as well as an 8020 frame.  We received a quote from [[tslots.com]] to make the frame for about $250 (50% off for schools).    I think the 8020 could be more simplified, and hence cheaper.
+**2016-10-20** - We updated the folder with updated documentation, including spreadsheet, and self-printed disc brakes.
-Steering - AZPartsUSA.com will give us 30% for their products, which could be the steering system.
+Other components:
-Motors - our concepts used a 24V 350W motor from monsterscooterparts.com, and their throttle, motor controller, etc.  Will work on a discount there, but also contacting myamigo.com to see if they would give us old scooters.
+Steering - [[http://AZUSAParts.com/|AZUSAParts.com]] will give us 30% for their products, which could be the steering system including everything from spindles/brackets up to the shaft.
+Motors - our concepts used a 24V 350W motor from monsterscooterparts.com, and their throttle, motor controller, etc. They will offer a 5% educational discount.
 Electric - we have been using a pair of 12V SLAs, and the monsterscooterparts controllers, throttles.
-Brakes - yeah, we're working on that.  Probably should prioritize it, currently using FF method (Fred Flintstone).
+Brakes - We went with a rear axle, keyed a 3D-printed disk to it, and using bike disc brakes on that.
+Wheels are from [[http://AndyMark.com/|AndyMark.com]] We are trying their 4-inch rubber tread wheels, 32 tooth #25 chain sprocket, [[http://VEXRobotics.com/|VEXRobotics.com]] was for hex shaft for the rear dead axle, and hex bearings from them too.  If you beat this kart up, wheels will eventually break (that's not brake).
+When we total it up, we estimate our kart will cost less than $500.
+We created our part supplier list, it is also posted in the folder linked above!
