before going too far and fruitless debate, lets focus on the question,
I'am not tamiya or hpi fan neither hate them, just my comment,
macgyver1432000, please go to tamiya website, then download and take better look at Tamiya TB02 TBevo3 exploded drawing
we can see there is 1 piece prop shaft
it directly joint front and rear pinion, in the perfect world where chassis no flex at all, then no crash at all.. this can be accepted,
sadly on real world, this is horrible design, there's chassis flex and crash,
then, prop shaft could bend slightly after crash or using high power mod motor, then this would turn into bad/inefficient gear contact/mesh in front and rear diff..
it wouldn't turn at correct rotational axxis after it is bending, even at slightest level,
I think the drivetrain design is the major flaws of tb02 / tb03,
maybe the design is taken from Tamiya Mini 4wd racing.. where's the driveshaft is made from high tensile steel,
here's the old one, nobody recognize there's a major flaw up there? http://www.tamiyausa.com/product/ite...oduct-id=58299
admit there's a major flaw there, Tamiya correct this on evoIV where they have 3-pieces prop shaft design, somethin' already used long time ago on our old TC3...
then you look at HPI Pro 4 (..or even older TC3...
) exploded drawing, we can spot 3 pieces prop shaft which is more suitable for real world,
I suggest, if you concern on good drivetrain performance, pls delete the 2nd first option then go direct to 3rd option, or take Evo IV if you are tamiya fans,
