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.

This oversized nosecone is still available from certain vendors. Standard front wishbones should 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.

Most builders will tell you a full frame takes some time, Dave W. Additionally, the car was designed using CAD softwareeliminating the measurement errors inherent to the original design.

I haven’t detailed the build process in this section as the many photos on this site describe how it developed.

Scratchbuilt 1/10 scale Locost chassis

I liked the chassis in bare white plastic, but I thought it would look even better in Humbrol’s Polished Steel. There are some vendors manufacturing nosecones that are taller than the book design to provide even more height for the engine.

For modern high-performance chaesis, 30, Nm per degree is the target. The last part of skinning that I added was the rear bulkhead, despite the rear end still being unfinished.


The remainder is to be built from 1. Various projects have analyzed the strength of the Locost Chassis under Finite Element Analysis for interest’s sake.

There are three drawing packages to choose from. Therefore I should not have painted the chassis steel colour overall. You need to locosg what is it you really loclst, and for what purpose.

SkinnyG, so that’s 11k plus shipping, ouch.

Another error involves the floor panel. 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 The rear of the Locost is of course “inspired by” the Lotus 7. Caterham vs Locost Frame. Also the rear frame around the differential is a lot more complex. In Australiakit cars must pass structural testing for certification for road use. I obtained a great set of detailed plans from Formula Motor Sport in Queensland and incorporated many of their ideas into my chassis.

Many different companies make and sell parts and complete kits for building the car. Does anyone have pictures of the Caterham’s for a side by side comparison? Martin Aveyard balsa frame for a car of his own design, and the finished balsa frame.

Not an error but more an improvement: Details of the transmission tunnel, suspension brackets, and triangulating strength members are not provided in any of these drawing packages. I used Tamiya’s Ultra Thin glue to bond 0.


The FEA is known to show the original Locost’s design to be slightly under engineered. Most locost builders probably did not even buy two different size gages of vhassis. It didn’t have to fit in any collection of a fixed scale, so that was another excuse for this non-standard scale.

A locost frame is chassix to built then a Caterham frame, so it’s just normal that the frame will be cheaper, and actually a complete locost frame is more like and there not even skinned. Generally I managed to build the chassis within 0.

Considering the daunting masking job inside the cabin to correct this, I will most likely leave the model this way. Tue Jan 06, 2: Each car is highly individualized according to the resources, needs and desires of each respective builder. Please help improve this article by adding citations to reliable sources. Ron Champion published his book in Mk6 — Seven — Mk8 — Mk9 — Eleven — It is assumed that donor parts and personal choice will dictate the final geometry of the transmission tunnel and suspension.
