When the design of this chassis is complete, full plans will be published. However, I started this design with a chassis bought on Fleabay. Building an modifying the “Locost” chassis design to work with AE86 Toyota Corolla drivetrain parts. I’m doing my due diligence and have copies of many frames but still unclear on the major difference between a $ frame and the frame on.

Making 17 of them was a tedious job, no fun at all. If they are designed badly, they will have a low torsional stiffness, which will make loocst less than desirable road holding.

I don’t have a side to side comparison pictures, but there were a few comparisons on the Locostbuilders. Not to be confused with Locust car.


The rear of the Locost is of course “inspired by” the Lotus 7. Also the rear frame around the differential is a lot more complex. An evening of work finished the chassis. The scale was chosen for lcoost It seems the dimensions of the rear section are not correct.

The increased height goes through the horizontal portion of the chassis forward of the dashboard to balance the over all design and accommodate taller engines. Jay Dagless 8th scale Porsche with a full frame.

I used an old tin that had thickened and needed thinning, and a fresh tin that was really thin. In contrast to the Locost’s space frame inspired chassisthe Locust uses a ladder chassis and a body constructed from plywood skinned with aluminium.


Approximately 10 as of April cars have been completed and passed by their countries government for use on the road. As you can see, I had started base-coating locsot model too, using Humbrolin search of building defects.

Locost chassis build

Please help improve this article by adding citations to reliable sources. The top was 20mm chipboard with 90mm x 30mm pine supports glued on the long edges and a steel tube frame underneath. I would bet a lot of the builders that purchase a frame, find that out the hard way. Chasis Jan 06, 5: You still need to finish the transmission tunnel, add the supension brackets, transmission mounts, motor mounts, clean it, paint it, and put on the aluminium Also, I shouldn’t have base-coated the model in grey paint, since its roughness showed, especially inside the passenger compartment, where the overspray settled down as dust particles.

Additionally, fiberglass body components, suspension pieces and other Locost-specific components can be sourced from various suppliers. Standard front wishbones lcoost bolt right up assuming the track width of the donor axle is exactly 4″ greater than the UK based Ford Escort Mk1 the book donor.

The chassis plans on this site are based on the original Locost design presented in Ron Champion’s book.

Scratchbuilt 1/10 scale Locost chassis

I have included some notes with the photos where appropriate. Concluding the construction of the space frame were six diagonals in the sides. By using this site, you agree to the Terms of Use and Licost Policy.


Tue Jan 06, You can download a Caterham frame example from the Google Sketchup site. Most car chassis are ‘space frames’ which are usually two truss sides connected with a collection of of transverse tubes. The Caterham is one of the very few clubman frames that has a creditable FEA analysis performed on it, which resulted in a design lcoost has three different size tubes and 5 different gages.

Chassis Plans The chassis plans on this site are based on the original Locost design presented in Ron Champion’s book. Not an error but more an improvement: I liked the chassis in bare white plastic, but I thought it would look even better in Humbrol’s Polished Steel. For a big pic, http: Paying respect to Mr. The increased length provides an additional four inches in the engine bay with a relatively “book” sized cockpit. I built the lower side of the frame on the drawing of page olcost, scanned, scaled to 1 to 10, and then printed.

IIRC it is the only Caterham that has double wishbone suspension in the back and chassid only one with inboard shocks in the front.

As an example, a Lotus Seven has a torsional stiffness of around 1, Nm per degree.
