Flying Lego Technic...!?

[Technic Jim]

...well, sort of. It isn't strictly flying, just sort of spinning around in a circle but it is propelled by a propellor and with all the motors and battery boxes integrated is probably the closest Lego will ever get to flying.

The original idea wasn't actually my idea but the work of ISOGAWAYoshito. He posted a video title HELIOPT3R - ROBOT REMIX#1 Yoshito (found here:

) and I thought that that looked pretty cool. It only took me 8 months to make one! Mine is a lot less complex than his and uses a RC motor for drive. The front facing propellor is for rotating it around and is geared at 1:1.6 from the RC motor's fast output. The top facing propellor is to keep the weight on the pivot point, a 3L axle with stop, to a minimum making the model more efficient. Here are some pictures of it:

Here is one of the gearing/transmission between the two propellors and the RC motor.

Two of the propellor. The holes you can see in the white background of the two images are from where I misjudged how close the propellor was to the backing. Whoops!

And finally a video:

Thanks for reading. I'm making a LDD file at the moment so that will be ready soon. Please leave any feedback or queries you have and I'll [try to!] answer them, Jim.

I wonder how fast that'll spin with the EDU propellers (large white, from renewable energy set)

[Technic Jim]

I dont know but they sure look expensive... I would also have to change the RC motor gearing output because I doubt it could drive them at its current ratios.

The set is about $100 on the lego EDU site, though some 'ambitious' eBayers would gladly charge you $300 for it.

I love that !

I love that !

Thank you! I was quite pleased with it as well.

The LDD file is now done but I cant upload it here for some reason. So, I've posted it on Brickshelf at my gallery, http://www.brickshelf.com/cgi-bin/gallery.cgi?m=Technic-Jim .

By for now, Jim
