The clutch has 3 plastic "weights" that are on 3 pins on the hub with an extension spring around all three that rides in a hub with a gear on the end that spins the trans in the center. The spring seems really strong and I don't know what RPM the motor spins at but it seems like it would take a lot to get the weights to spin out & contact the drum to get the hub spinning. Not sure what to do at this point but it runs good anyway.

Ok... the "weights" are your clutch shoes. They have both aluminum and carbon shoes (i.e. plastic) and various weight springs. The carbon shoes engage softer, allowing more slip... aluminum shoes engage harder. Lighter springs make the clutch engage at lower rpm, heavier springs at higher RPM.
If the clutch is engaging... (and it should be... it sounds like it is right) then something else in the driveline is messed up.
Where are you located? Is there a local track where people race? If so, someone there would surely be happy to help.
Based on your description though, I would suspect the center differential is bad, or one of the center driveshafts is not connected (dogbones) but without looking in detail it is hard to say. If you can remove the body and post some pics it might help.
