This is a modified chassis with Grasshopper type-1 base.
I am modifying Grasshopper type-1 series chassis continuously since 1984.
It's just an long term experiment with my studies of chassis design or practice for my setting skill.
:) / Front suspension assembly of DT-02 is combined to Grasshopper chassis with homemade bracket.
Each rear suspension consists of DT-02's lower arm, TL-01LA's upright, DF-03 aluminum front damper and titanium turnbuckle.
For lightweighting, titanium axle and 48mm aluminum dogbone were installed (but of course they're too weak against impact).
The monocoque is almost as original but was reinforced some places, also I had to make a heavy-duty battery holder because Grasshopper often bombed the ground with his battery. LOL
/ / Fig7: A counter-gear consists of three parts.
TA05's aluminum spur gear holder, stainless 16T gear and TRF415MS's shaft. / / Fig:8
Each looks are different but both WR02 and Grasshopper are using same 50 tooth final-gear.
WR02 diff has metal inner-gears and a heavy-duty sealed case.
So, its effect is able to adjust by kind of sealed-grease, just like a viscous LSD.
5.0mm shafts which have spline were taken from a DT-01's junk.
TLT-01 drive cups are combined to them, finally. / / Movie is following URL prease watch and enjoy.
