Open RC F1 Test Run

So above is a video of my printed F1 cars first outing. For the most part it works pretty well but there are a few teething issues to sort out.

First the tires I have printed have no grip. I printed them with far too much infill and they are no where near soft enough. I do not want to give up and go to Tamiya tyres so will be playing around with reducing the infill and making these softer.

Secondly as you can see in the video the front axle snapped, I have reprinted a whole tray of these solid so the next ones will be stronger and if not I now have spares.

Lastly its not very noticeable in the video but my servo pusher is rubbing up against the body shell and causing the steering not to return to center. This should be easy to fix but I need to unscrew the body first.

Open RC F1 3D Printed TPU Tyre

So the rest of my open RC F1 car is printed and it was time to get onto the most tricky part the tyres. The rest of the car was printed in PLA but the Tyres need to be flexible so they are printed in TPU.

The TPU brand I purchased was Enotepad. It arrived in a box that looked plain apart from a logo that reminded me of good old word art. The filament felt flexible to touch so it was a good sign it was not PLA.

You can find my print settings at the end of the post.
