Mode Zero

As part of our Eco-week I built a 2.2 metre cardboard motor glider

It's loosely based on John Beer's Zeitgeist (my favourite with reeds / propo) since the mid 70s...

It flies pretty well - but the motor had to go on an aluminium extension to get the CG somewhere sensible

I can see now why the Wright brothers didn't use much cardboard in their Flier...

Would go well with the HobbyKing cardboard-box transmitter

Genius!

Not looking forward to a rainy day

There's that Yorkshire man again Phil

If you had a slightly smaller model or a larger cardboard box, you would have storage, transportation, & transmission all taken care of. Perfect for the Van !!

As an aside, does the van have a knickname / alias? Van Morrison, or Van Halen, or ??? Your mates on MZ could help, of course

Some video

Going to try it off the slope soon

Tried this back in the 80's and gave it away as a bad idea, not worth the effort.
Whichever way one looks at it, cardboard is simply way too heavy.

Some IKEA packing has a kind of honeycomb style cardboard inner core, and light card/paper on both sides. That stuff is very strong, you can stand on it. Quite light, but possibly not light enough...

Stew.

You are right - cardboard it stupid and if it hadn't been Eco-Week I wouldn't have done it (and had a big box)

The motor is very heavy and already on an aluminium extension.

I tried to keep the weight down at the back end - but no joy

It's an all moving fin (easy way to replace with a depron one if really heavy back end)

Does fly well

Hello
A friend made a conquest for his club, look this video

thank for all

...it sure can be lot of fun!!!!!
We use to do something similar but with empty pizza boxes and always had a ball and occasionally some actually flew!
