3D printed replacement Losi XX chassis.

This is a direct replacement chassis for the Losi XX buggy series and is compatible with all original Losi parts as well as the VRS replacements. The geometry is identical to the original but with the shape tailored for 3D printing and to suit the current UK Iconic Revival rules and modern electrics. It has been submitted for approval to the Revival team.

The chassis is set for running a shorty LiPo in the forward position, with the speedo located directly behind. The spacing under the LiPo is for Revival legal stick on weights in 10g increments, with 2 able to fit in each bay. The maximum limit is 50g in Revival rules, so there is space to move this around as the 3 bays allow for a total of 60g.

The side braces are 3mm thick Carbon660 provided by Fibrelyte (included with the chassis along with the fixings). They provide additional stiffness to the chassis to keep it as close as possible to the original, whilst also serving as mounting points for the battery straps. We trialled a full carbon fibre brace (too stiff) and a 3d printed brace (too flexible) before settling on this design.

The prototype chassis with the full carbon brace had a successful first outing at the Jingle Bells Cup in 2023, qualifying in pole for the B final and bumping up into the A final to finish 7th overall in the hands of Chris Ely.

Please note, the use of a metal front bulkhead is not recommended as the bulkhead was designed to fail before damaging chassis.
