Description
[¯`·._.·[  V9 WLTOYS 124 X CENTRAL DIFF RC CAR TRUGGY 1:12 PREMIUM ]·._.·´¯]
Â
Â
Â
ENGLISH :
Â
A beta prototype version of a chassis with integrated central differential,
Â
This should further improve performance, transmission robustness, and road handling.
Retro compatible with classic WLTOYS 124.No need to reprint all.
Â
There is
2 types of Motor/Diff Mount (and therefore chassis) :
– WLTOYS 104 (recommended and tested)
– HSP (not recommended for current use)
Â
3 Possible Differentials :
– VRX Cobra (recommended and tested, 1mm mod)
– Rlaarlo OmniTerminator (more expensive, good quality but 0.53mm mod…)
– Rlaarlo SBK 10 (more expensive, good quality but 0.53mm mod…)

(same as JLB X HSP until I write it up; it shouldn’t be too complex normally because the assembly principle is the same)
Â
Ultra-high performance 3D printable RC car, using standard WLTOYS parts.
Â
The design is improved, and much more durable than the original.
The parts are stored in folders with logical names but it is best to read the build guide.

Â
Â
There are two types of CVD, M3 4mm or M4 5mm.
Â
if you choose CVD M3 4mm official or enhanced from WLtoys 144 or 124 then you will need to choose 4mm bearings, and so you have the choice between two types of bearings, either the small official 4x8x3 MR84ZZ ABEC7 OR the recommended 4x9x4 684ZZ ABEC7 for more performance.
Â
if you choose CVD M4 5mm from WL toys 12428 12427 12423 then you will need 8x16x5 688ZZ ABEC7 AND 5x11x4 MR115ZZ ABEC7 bearings
Â
if you choose CVD M4 5mm from HSP 108015 10x19x5 then you will need 6800ZZ ABEC7 AND 5x11x4 MR115ZZ ABEC7 bearings
Â
Tips :Â CVD M4 5mm from HSP 108015Â is the best choice, with no change from direction, transmission and diffs and diffs cups only change arms and the CVDs and hub cup carriers front/rear and the bearings and that's all. You have the strongest CVD now.
