| 1.2 Pumpkin?
I've been really taken by the Tamiya Pumpkin hard body. It’s a class M body and quite a bit smaller than 1/10 bodies out there. The idea is that it would work pretty will with the 1/14 scale tractor trucks out there. I spent the last month or so tracking down axles and trying to find wheels to fit. This is what I found so far. Redcat 1/16 crawler, and the new Axial 1.5/1.2 Yeti Jr wheels. I may step up to some 1.55 rims and the RC4WD 1.55 Dirt Grabbers. |

That's going to be awesome! I don't know the measurements, but you could look into the MST CMX and Losi Mini Rock Crawler/Slick Rock axles. |

The vaterra ascender axles have small pumpkins and can be narrowed quite a bit easily and may fit the body. Ben |

I don't like agreeing with Jato, but check out the MST CMX/CFX chassis and/or axles, they match the Tamiya CC01 body dimensions. Sent from my iPhone using Tapatalk |

The axles were the hard part to find, the CMX was too wide. The MRC was to narrow, not to mention a bit tough to source now. The new Yeti JR and trophy truck actually had the right width and wheelbase, but those diffs are open and I wanted a solid axle up front. Thunder Tiger makes a 1/12 scale along with ERC, but I think they would be a bit wide as well. I wanted the tires to tuck into the wheel wells. I settled on the Redcat 1/16 Everest as a donor truck. With a bit of work they should look like they belong on this truck. The real trick will be to figure out how to stuff a 2 speed transmission in this thing. |

My Pumpkin body on a modified mini summit does a pretty good job at crawling. A 4:1 GRU, a Dynamite "Taser" esc, and 1.9s help a bit too. BUT ... I had to do some mod's to stretch the suspension to get the wheelbase to match, and I don't think you could do it with the Slash arms. Mine stands a bit wide, but it sure put new life into my 30 yr. old Pumpkin. And it still gets more run time than all the rest. |

Slight change of plans. Using the axles off a Redcat Everest 16 they seem to fit under the Tamiya Jimny body much better. Ordered some bits from Shapeways and they arrived yesterday! Had to make a custom nut driver to install the ball links. I'm trying to re-use as much as the donor hardware as possible. |

I couldn't find anything off the shelf and wanted to avoid using straight frame rails. I ended up drawing them in Fusion 360 and having Shapeways print them out in nylon. This is a much shorter wheelbase than the Pumpkin and I would need to modify them to fit. There are a few new 1/14 scale crawlers that have come out whose axles would fit better under the Pumpkin IMO. The ones off the 1/16 Redcat Everest would need spacers and the shock mounting is not ideal but could be made to work. |

Once I wrap up this project I was going to pick up one of these and mount the Pumpkin on it. The only modifications needed would be to shorten the wheelbase by 15cm. TOYOTA HILUX 1/12 PICK-UP TRUCK-Thunder Tiger |

I'm not sure about the Lunchbox, the Pumpkin and the newest Jimny body from Tamiya share the same wheelbase I think. Some progress today. I got some 1/18 ECX shocks. The stock springs are way too stiff. Pulled the oil out of them and dropped in some internal springs. Fab a front and rear bumper as well. |

Here is a bit of a size comparison. 1.9 and 2.2 VS. SCX10 |

Man, those Tamiya sticker sets take forever. I left the headlight lenses clear to add light buckets at a later point. The next bit is making sliders and finding something to cut wheel wells out of. |

Thanks! I cobbled together some sliders and took it for spin in the yard. https://youtu.be/tkxASclVXZc |

I've got some light buckets installed, waiting on brake LEDs to show up. Also mounted up an obscenely large winch on the front. I have some 1.5 wagon rims and dirt grabbers on the way, but I'm kinda digging the undersized tires. I'm kinda wanting to do the same thing to a Lunchbox. |
