Introduction: K'nex Tricopter Model!!!

Picture of K'nex Tricopter Model!!!

After building my K'nex quadcopter model, I became fascinated with other kinds of multirotor drones. I already knew I wanted to build another model, and when I saw the tricopter, I knew it was the perfect thing to build. When finished, the tricopter was just as realistic as its four-armed couterpart, this time featuring a central suspension and four-bladed rotors, all while being an actual-size replica. In this Instructable I am going to show you how to replicate my building process and build your own K'nex tricopter model!

The beginning of the story can be found here.

The story ends:
Now having satisfied my curiosity with the workings of multirotor drones, I now have a lot of new knowledge! One question still remains: can anyone make this fly? Anyone who can gets a patch and sub from me!

Thanks for viewing! Enjoy!

Nice! But I like more your quadcopter.

Yeah, me too... But to change it up a bit, (cause I know you're getting tired of hearing me say "thanks!") I'll say it this way: Bedankt! ;)

Haha bedankt to say it with anothor word, phewww =D

How did I miss this??? This is pretty cool, but man... That thing uses a lot of bendy rods. :3 Getting this thing to fly, I'd think, would require a much lighter box in the center, and most likely tape all around the wings and box so air doesn't leak right through it. Nice job!

Well, actually tape would make it heavier. But i think ot could fly. :P multirotor drones dont have to be airtight... :P :3

Haha cool, must have been sorta hard trying to position the wings into three even places!

Oops... I totally forgot to click the reply button there... Sorry...

Thanks! I tested out the idea using blue rods on a white connector. ;)
