can any planes that are made out of knex actually fly? Answered

can cay of these planes actually fly, or get airbound?


I doont know if you are still asking but I am woorking on one now. Its looking hopefull but will take ages to build ill let you know.

Your gonna have to ask daredevil499
im working on aircrafts
any questions??

You'll be posting the I'ble when you're done, of course?

It's not as simple as I thought. I give up.

Late reply much?

 No i dont think its possible

you could but the ammount of work you would have to do to get it airborne would not be worth it in the end. If you want a plane just buy a rc one

"Of cource it's possible, yust combine 20 meter long wings and a jet-engine."

It's possible to make one, but if it needs to stay in the air for a long time, you will need to add some cind of engine. (I somtimes use a knex solar-cell for moving parts)
Begin with small hang gliders, to get used to making wings. If you want to make bigger aircrafts, you can better first practice flying in Flight Simulator to get used to all the aspects of aircrafts.

Oh, and don't forget you will need to land too. Landing gear will be verry usefull.

lightest motor i know of is the wind up ones.

maybe a 2 way connector connected to a red connector with flexi rods would generate lift and if a knex motor was light enough and the propellers were identical to the wings but smaller MAYBE you could get a plane.

will you need to kick-start it?

it is theoretically possible, barring the correct conditions. first and foremost, you must have a much more powerful engine than knex makes. Also, the wingspan would have to be large or the weight of the craft must be low. ( with the properties of knex, neither is possible.) The only way i can think of for this to work is to use a hang glider design with a carbon alloy v 12 engine :-)

build a flying wing, cover in chinese paper (tissue paper) or plastic wrap.

I agree with the burrito master.


I made one in the fourth grade.

Design? Photos in flight? In particular, how did you make the airfoil?

I built it years ago so i do not have photos or remember how i made it , but i remember it was made out of knex

The problem (obviously :-) is the lift/weight ratio. If you can use K'nex parts to create an airfoil frame (and then cover it as the_burrito_master suggested), then the question is whether you can make the wing large enough to provide lift without the weight increasing as fast or faster.

you could make a simple frame ,cover it with plastic wrap ,and use a hair blow dryer to tighten it up.

I don't really think you can make a flying plane with knex only... Maybe its possible if you make the frame out of knex and use the other parts from RC Planes.
