Hey there! I'm participating in the F1 in Schools challenge for the second year now and would like to gather some pointers on which materials to use for the external components, including wheels, axles and aerofoils (wings).
We're looking for materials that are very light (we want to reduce the mass as much as possible) but also mechanically strong, whilst minimizing drag obviously.
Last year we used ABS wheels, axles and aerofoils. The ABS was a satisfactory choice as a material for the wheels, in terms of performance, but it was a problem when it came to the axles or aerofoils since it wasn't mechanically strong enough.
I was also looking for guidance when it comes to picking bearings. I've made a quick search on this and the variety offered for the competition is huge. I don't really know which type of bearing to pick and where to purchase it.
All help is welcome and thanks in advance, really appreciate it.
