Formula 1 might be constrained by four million regulations but it does still occasionally provide good racing. The surprise of the 2015 season has been Ferrari, who after a woeful 2014 seem to have mostly sorted their latest car. Don’t underestimate the role Vettel played in fixing the prancing horse though – as his previous team Red Bull seem to be going backwards (and doing so very ungracefully too). Coincidence?

Anyway, one of the more ridiculous of the four million regulations in Formula 1 these days is the DRS (Drag Reduction System). It’s a neat engineering solution that should be able to be used whenever the driver feels like it, not just when Bernie Ecclestone’s computer deems it to be OK.

TLCB regular Sariel has created a Ferrari-ish Formula 1 car that uses this feature the way we would like – his working DRS on the rear wing is deployed automatically in top gear. His fully RC model also features pushrod suspension, return-to-centre steering and a range of other Technic functions. You can see them all on MOCpages, plus a video of the car and its DRS in action.
