*Note: This 3d printed kit fit nicely on 1:24 scale R/C model especially on 1:24 scale SUBOTECH CoCo 4WD chassis with slight modification to electronics placement and shock mount, but if you need to fit into other 1:24 scale R/C model chassis or nearest size you will need to manually re-scale/resize the *.STL parts before printing and also the decals that comes with the package. However the wheels that comes with the package only will fit on SUBOTECH CoCo.

About: The GRASSHOPPER
First time when i saw a TAMIYA GRASSHOPPER was in 1989 when i was walking about at town area encounter some R/C people bashing around few 1:10 scale R/C buggy at local dirt track. It was very obvious to spot this particular buggy because in contrast it was the most slowest buggy around no thanks to its stock 380 size motor unlike standard 540 size like on TAMIYA HORNET and others....i love the HORNET unfortunately i have no love for the Grasshopper back then not until few decades later i started to like it more and more due to its scale looks which is closer to real life sand buggy, dune buggy or sand rail or whatever off-roader that exist in real life.
The GRASSHOPPER was first release in 1984 meant to be low grade beginner or entry level basic off-roader for R/C buggy enthusiast to step into R/C buggy world. Cheap package, 2WD, tub style chassis, friction shocks, simple suspension system and very sturdy ABS bodyshell insetad of plastic Lexan. Its the only buggy very that seems to close exist to real buggy unlike over engineering AVANTE or SUPER SABRE which hardly exist as real vehicle in real world. To keep the story short i decided to create a 3d printed replica of the TAMIYA GRASSHOPPER in 1:24 scale to be fitted on 4WD SUBOTECH Coco platform as to compliment my nostalgic childhood moment encountering this cool scale 80's buggy. Since it was a 2WD i manage to 'visually' tricked out the looks by creating the same replica front 2WD wheel size of Grasshopper buggy on active 4WD platform unlike my previous project replica 3d printed TAMIYA kit on SUBOTECH.

Complete assembly parts:
Fitting the electronics into the frame will need a lot of work and bunch of fine soldering skills especially for power wiring connected to ESC and brushless motor. Because its so compact you will need to remove any plugs, surplus wirings and etc if necessary to get it fit perfectly
- SUBOTECH Onboard integrated electronics bulk plastic case box need to be remove to expose bare electronics PCB board to allow more compact fitting under the 3D printed body.
- Front suspension shock mount/tower mount need to be remove and the top shocks eyelet shifted to lower position and screw in place where the shock mount lower based was screwed in.
- SUBOTECH stock rubber tyres need to be carefully peel off from its wheels, the tyres will be mounted on newly 3d printed wheels.
- The downloaded package already included re-size decals for A4 size colored printing, you can print directly without needed to re-scale during printing.
- Some parts assembly need to be snap-in and glued together.
- To attached the completed 3d printed body/parts onto the R/C models chassis you may need to DIY or improvise self create solution to do it. You can either fit it together using sticky 3M double sided tape under the body, fabric Velcro, using magnet post mount or using back traditional snap pin to the body post mount which required to drill a hole on the 3d printed body..its all up to you to think about how to mount it especially when mounting on other type of chassis other than on SUBOTECH CoCo model.
Your shopping list to buy parts to build the above model:
* You can also use other type of 1:24 scale R/C chassis as long you can manual scale or resize the parts accordingly.
