Do you think it’s impossible to make Lego fly? Then you have to watch my “Flying lego”! Without the use of any non-Lego parts I lift Lego up to 5 meters into the air. Enjoy your flight!
About this creation
Watch my video:
The “flying Lego” MOC consist of three elements. The launch base, the propeller and the rip cord.
The Propeller is the flying part. To make this I looked at the propeller of a helicopter. For this the angle of the blades is very important. I tried all different Lego Technic angles but only with angle number three the propeller makes a lift up into the air.
There is a turning disk on top of the Launch base, in this disk are three blue pins. These connect the propeller with the launch base, but the propeller is still able to fly up.
With the rip cord you can make the turn disk spin. I tested lots of different transmission ratios for this MOC, but the best one consist of just one little gear.
Warning: If you want to make something like this too. Make sure you take enough space and protect yourself and others.
Just spotted this in the ABS Forever group. I remember having toys like this as a kid. It's a great idea for a Lego MOC. You've solved the engineering problems (strong enough base & rip cord, light but strong flyer) really well and produced a package which works and looks good too. Nice work!
I like the way you reduced your flying machine to just the propellers - it saves a great deal of weight and also very clever! I was able to duplicate your results. I was able to replicate your propellor exactly -- with the pitch of each blade oriented the same direction. I was able to make a similar ripcord ( 8.75 inch gear rack). My launcher is similar but not exactly like yours because I didn't have the same pieces but it works all the same using an 8 tooth gear to drive the propellor shaft. Using a lower power ratio gear (more teeth) does not transmit enough speed and failed to get the propellor flying. Build problems that I found: (1) the ripcord had problems staying together if too much force was applied - older lego pieces had less clutch power. (2) The fit between the launch gear and the ripcord gear rack was loose so energy from the ripcord didnot always transmit to the launger gear drive.
Great! Of course, you could just use the Rhotuka spinners, but doing this in a different way is a fantastic challenge. The desighn for the propeller itself is the genius part, I think. Now I want to see a Lego helicopter.
Honestly I knew this was possible, since Lego made those weird little launchers for Bionicle. I'm just impressed that you caught it. I always end up hurting myself when I try running around to catch them...
lol! funny animation! wow! you keep amazing me with all these experiments! keep going, if i recall the ninjago spin, you improved a lot for the second prototype, may i ask, would nt it be better to have a stronger center for the pales? with something attached to it, [like a small copter body] would nt it make it more stable to rotate? [hence flyin higher longer] even with more weight, with a faster rotation it might be attainable! good luck!!!
5 are heads not enough you get 10 heads! You just brought back great childhood memories! THANK YOU I had the very toy you demonstrated made up of metal parts! I saw a plastic version of it bout 12 years ago then no more. Being an only child this toy required no one else to play with. The video was great and a funny beginning! A bit fast though for us 62 year olds with SLOW eyes (lol)!
You must stop by my MOCpages!
Oh, loved the fact it was done by a GIRL!!!!!
