The silent_runner is a small high performance model airship with a full do it your self documentation available at:

All parts are cheap and easy to assemble. Build your airship today and stop wasting battery power to low efficiency planes and quadrocopters, but start over with endless endurance and amazing grace.

The whole project is undergoing finetuning and improvements, thus feedback is much appreciated.


Silent runner i4 datasheet:
length:.......... 2.1 m
diameter:...... 0.5 m
mass:........... 300 g

The silent_runner consists of several parts and materials, including RC electronics and printed parts.

Printed parts as listed here should be sliced and printed with care as they are optimized for low weight and thus have a filigree structure. You need:

1x front rod connector
1x motorring
1x motorring1
1x motorring2
5x rudergelenk
1x ruderhalter 1
1x ruderhalter 2
1x ruderhorn

The full documentation including a full list of parts can be found under the following link:

This project is initiated and together with the greatly appreciated help of other helium heads developed by the Projekt Windreiter team: www.windreiter.de

what kind of air did you use to put inside it?

We use helium.

The crowdfunding campaign was successful! Stay tuned for the updates of the silent_runner design towards less weight, easier handling and more crash resistence!

The next iteration of the silent_runner is going to launch in a startnext campaign. Become part of the story and support us as a fan or preorder the silent_runner I4 DIY kit!

A recent version of the silent runner at the phaeno science museum:

A detailed step-by-step set of instruction, how to assemble a silent_runner, was compiled with a lot of images.

Found in the wiki under Documentation

The next optimized iteration can go with a Latex Balloon, that is super robust and cheap at the same time:

A silent runner won the airship regatta held by the Airship Association:

And an outdoortest was flown recently:
Performs quite nice in calm conditions.

Another silent_runner was built with some about 16 year old pupils during a school project: http://youtu.be/2Egyc1NfYWkhttp://youtu.be/2Egyc1NfYWk
Watch the crash actions in the end ;)
It was fun and the students were quite able to do all the tasks to build one.
