Every EVO 3 drivers in my area have to sand and tape the gearbox to tried to fix the pinching of the bearings and also tape up bearings, fix on to the angle gear(sorry not not knowing the proper name), of the slop from moving up and down.
If you look at RC World in Japan this month, they talk about the TB-02 which share the same gearbox as EVO 3 or EVO 3 SL. Look at that gearbox will give you a good indication of how accurate and quality control of that plastic mold.
Tamiya team driver use graphite gear box for their EVO 3 not the one that LHS are selling to us. Graphite Gearbox is not for sales to the public, only team drivers can use it. All shaft car have one common problem, pinching of the bearings.
Maybe EVO4 they will give you graphite gearbox instead, let's hope so!!!!
TB 02 used the same gearboxes as the first one, the TB 3 introduced new gear boxes.
If only team drivers have got Graphite gear boxes, it's because they couldn't reach a good quality for them, only 10% were suitable, so they'd have been very expensive.
About the Tech car, IMO it's just a custom chassis for the TB3, nothing to do with the TB4. Only thing is that their 3 piece propeller shaft might have been a test part.
