If you are racing or bashing your Tamiya Subaru BRAT, Lancia 037 Rally, The Frog, or any other ORV (Off-Road Vehicle) chassis radio controlled model vehicle in extreme conditions like a skatepark with huge jump ramps like quarterpipes, even with XTRA Speed G45 Steel CVD (Constant Velocity Drive) Shafts you might have the driveshafts pop-out during a particularly hard landing on cement or metal. How do you fix this? SPOILER-ALERT: You have to downgrade to Tamiya UJs (Universal Joints) and add a gearbox support brace or tensioner. We drive at a continuous velocity to the shaft of this issue to find the constant universal truths that cause this issue in this episode of the RC Deep Dive podcast. 

[NOTE: If you aren't regularly bashing your radio-controlled car, truck, or buggy on very tall extreme cement and metal skateboard ramps, we still recommend the XTRA Speed G45 Steel CVD Drive Shafts over the Tamiya Universal Joint Assembly for ORV R/C model vehicles.]
