Another short test drive today, and the 4th wave spring in the Slipperential makes all the difference in the world. It will throw the front wheels up in the air at will. No slip at all. I have it locked almost all the way. I will let up on the slipper so I can have just a little bit of slip. I don't want to have any problems when landing jumps on the throttle. It acts just like my plastic brushless Emaxx without the broken drive shafts and bulkheads.
I can't believe it considering it is 13lbs!!!!!. I still have to order my Hitec 7955 servos as this is nearly impossible to keep straight
I think it will be near perfect once that is worked out.
