42074 Airboat Racer




This Airboat Racer is an alternate of 42074 Racing Yacht.

The propeller in the back is driven by one of the front wheels. All gears from the original set are used here.

It's inspired by similar Lego models like 8223 Hydrofoil, which was by the way my first Technic set as a child. Although I don't think hydrofoil is the right name for such a boat. Other similar vehicles include the boat from 31023 Yellow Racers. 42045 Hydroplane Racer however is a different kind of machine, as these are not driven by airborne propellers. So I named this one Airboat, because the propeller is clearly above the water surface. Unlike those airboats used to travel the swamps this one however is more of a racer.

    Is there a way I can tip you as a designer like on thingiverse or something?

      No, I don't have any account for something like that. However I would appreciate if you could share a photo via the photo tab above when you are done building the model :)

    Currently I am learning for a test with manymany questions, like 1000 multiple choice for my driving license on water. I bought the Mercedes Benz Arocs for my driving license on the streets and put for every correct answered question one part in the build (in germany there are like 1200 questions for driving on the streets). So Now I was looking for a nice build I can recreate! I really am enjoying the questions right now hahaha! Thanks for sharing - I let you know when I did the exam
    It warms my heart that people are creating these builds and even instructions and - put them for free here

      The community idea is very important to me, that's why my models are free. Good luck for your test!
