Electric r/c kart

1977capeta · Oct 21, 2009, 02:41 AM

Hello there,

I'm a new member in rcgroups and i would like to share my work to all of you. Not really sure is this the first electric r/c kart with the moving figure in the world!~ Anyway it's nice to share.

first electric kart? no. first electric with moving driver? maybe. (the Carson nitro kart has a moving steering wheel and arms). seems like the driver figure was taken from a kyosho HOR bike. but from what i remember in karting school you're supposed to transfer weight to the outside of a kart, not the inside because karts don't have differentials and it helps around the corners to unload the inside wheel.

can't tell for sure from the video if it is the Cross kart. http://www.rc-cross.com/page/english/newproducts.html

also coming soon from Thunder Tiger - the KT-8...

Nice kart. I had a interesting question a few of us kart racers were asking each other while were playing Friday night wii bowling

. Why go through all the trouble with the rear and front A type suspension for a gokart? Karts have none of that. Basically someone can toss the carson gokart body on a touring rc car. Benifits would be, you'd have 4 wheel drive n shaft drive to boot. However, it really wouldn't be nor drive like a real kart with all that "car" suspension and high tec setup.

designing rc cars is a balance between scale realism and functionality. one can design a miniaturized version of the real thing but will probably run like crap on the track. if a person is looking for full on scale accuracy then they're better off buying a diecast/static model. what's the point in having a super realistic looking RC kart if it is basically undrivable? i'm sure a lot of kyosho and carson kart owners know this frustration.

the 'suspension' on the KT-8 is not complicated but rather very simple - it doesn't have shocks nor springs nor hinge pins. instead it works on flex as on the real karts. it looks different but the concept is the same. this kart was designed to have good mechanical grip such that it works well even on unprepared bumpy outdoor surfaces using rubber tires.

to be nitpicky, real karts don't use transparent lexan wings nor do they use low-profile foam tires. yet there exists this type of "kart"

That actually looks really cool...LOL

No offense taking with the "lexan" wing. I personally don't run one due to my kart setup. The image you posted is Roberts modifed kart. He's the owner of the 3 companies I believe. He was down a few weekends ago and raced with us all. It's very fast on the track. As for the wing one last time? A bunch of us race karts in serveral states here in the U.S. very seriously. No different than that of rc classes you view online and in rc mags. Theres 3 rc kart classes: stock, mod and spec class. Many of the rc kart drivers also race the U.S. touring circuit, 1/12, oval and off road. Many drivers bring their rc knowledge to the tracks and events. As said, many use the "lexan" wing for on road and oval class. It does actually work and fully functional. If you used one on yours, you would not have the rear slide issues (per video)and obtain better lap times as well. The only guys that run the wings are modified class. Most run the wing for oval. As for the chassis design you run, I like your kart but forgive me, it looks just like a touring car chassis and very out of scale. Karts are not long and narrow wheel based. They're short and more square like in wider chassis design. I raced in the full sized 125cc kart class. It's front wheel base was narrow and the back were always 5-8 wider. When I raced gokarts our chasiss's and even current rc versions, carson, B, and older Kyosho were also desinged the same way, short n wide. They use square n short kart chassis design's for quick cornering and tight short tracks. Lap time also decreases by such design. Of course, I do not race full size gokarts anymore. I got to big

and couldn't be competive no longer. Your kart does look tight with the movement and all. Very real looking less the plastic behind the driver and other non gokart suspension designs. Couple of questions, Hows the run time with the extra movement of the figure? I guess it would be no different than those scale rc motorcyle yes? Is there plans to make the wheels not stick out from the body pieces unlike a real kart?

Thought I'd follow up real quick so I don't look or sound like a know it all. I know how some are in the forums. The suspension issues on your kart, since it's in it's in protype state was to help you out a little. More so as for the overall kart, rear axle and tire appearence like the posted image below of the New Ky kart. Circuit racing goKarts have a straight axle, not a split or dogboned unless its something of its own yet "new" class. As for the square chassis design I was speaking of, it to is pictured below for refrence in your build. Notice the chassis is more square not retangled. The width of the rear and front tires are not equal. Once again, if you look at the kart above or straight on, the front and rear tires are not the same width. Just offering some help since your karts in the building state. Not critizing your build just helping to improve and the appeal.

Hi, i see Diego's kart on your picture, i post new picture of the DMR 1:4 scale kart. Hand made by Diego Lombardi (standard 1:8 car wheels) 3.5 engine. Ciao Mirco

1fastrckart · Nov 09, 2009, 10:54 PM

Now thats a cool kart bro. Looks to have alot of detail similar to the ones we race! Not no touring car in your pics by all means, a frame, one rear axle and 4 wheels to roll on! Look, there's foam tires to

Some ones serious about rc racing like us. Very tight kart!

I take it your also into rc bikes huh? Use to own one till it got ran over in a parking lot. Stopped it, it fell over and couldn;t get the car backing out to stop.....CrUnCh! Love to grab another, maybe next year.

n2rckarting · Nov 14, 2009, 09:28 PM

I agree fastrckart. Great build. When I first ran across Diego's images I was impressed.
