Our next Carrera Panamericana is coming up next week but unfortunately I have a conflict and will not be able to attend. I have however been working on my Lancia D24, making many mistakes but learning a lot. I’ve finally overcome the engineering challenges of fitting a 3D printed chassis in such a small car with a short front overhang. The front axle is independent and uses 2mm grub screws to adjust the ride height. The rear axle has a 1.5 mm offset to lower the C.G. which was the most I could use and still have it run smoothly. I’ve been able to get the ground clearance to just a hair under 2mm and the weight should be under 57 grams with interior, wheel inserts, exhaust, accessories and paint.

The resin body was warped during printing or curing so I had to use a hot water bath to straighten it out. On close inspection of the body the layer lines were  visible and there is either a run in the resin or the primer but some diligent sanding should improve these. I’ve designed but not yet printed a basic decal set and I hope to add decal based headlights and tiny gauges.

I’ve included a few photos showing my progress. Doing everything from scratch has shown me how interconnected everything is and how a small mistake or mismeasurement can seriously degrade a cars performance or stop it running at all.

I hope you all have a Happy Easter

Cheers

Steve
