Introduction: Knex EDF Powered RC Car!

About: My name is Elliott and I play guitar and skate. and I own a website: www.elliottstutorials.com

Hey guys, I'm back and I bring you my RC knex jet car! took about 2 hours to build and it goes about 50mph+ (Fastest knex car?) I used equipment from my old RC jet which could go about 90mph+
I hooked up a servo for I could have some steering aswell :)

I will do a video of this beast when I have ironed out the kinks!

Also when it crashes it pretty much explodes! XD

    i had the same problem i couldnt fit an air compressed tank which was in my old rc jet which went over 50mph because of the air compressed tank but unfortunattly it wouldnt fit in the buggy i was building it took me weeks to make it now all that hard work went down the drain

    that is great but how are you going to steer it doing you need more steering room

    nice looks cool maybe have a look at mine ? https://www.instructables.com/id/knex-forklift-1/

    it looks really good so whiy dont you next time try and make a knex plane or somthin i realy dont know if it is goin to work but it is worth a try

    i build a knex rc but i connected a standard knex motor to the wheels,it goes boringly slow, i quit. maybe this kind of fans will do the work. isn't it noisy? how fast do the batteries run out?

    It sounds like a jet when it gets going so yes it is very noisy and the battery lasts 10 minutes.

    looks good. it stinks that it has to use parts like that though. try hooking the fan up to a rubberband or a geared up motor :-)

    well, if you make the fan part out of knex, and attach paper to make the fins. then you attach the motor to the drive rod of the fan. anyway, i don't know if thats going to work or not.

    Nice. Looks pretty good. Might want to try adding a sort of bumper to help soften the impact? Unless you like big explosions...

    That "little fan" is from an RC jet, a very powerful one. Also the frame is light, thus giving it even more propulsion. Trust me it can go 50mph.
