Axial driveshafts – WB8 vs WB8-HD

A few weeks ago my brother bought himself an Axial SCX10 Deadbolt and because he doesn’t have much experience with RCs (yet ;)) I’m the one that became his main mechanic 😉 And thanks to that I had a chance to make this comparison. First difference between WB8 and WB8-HD is that the first one has 2 elements, that goes one into another, while the second has 3 elements – the middle one goes inside the two external. Perks of this solution is that the middle element can be made stronger (with thicker sides) and thanks to that it should be more twist-and-snap-proof, than before. Second difference the size and construction of couplers. In WB8-HD the pinion (and the whole part actually) is much bigger (and that’s good), but I’m not sure about the whole idea of making it the opposite way, with pinion under the ring that isn’t held…
