Team Kassanova K2v2

K2 V2

Almost a year and half later I am revisiting this project. You can find the first one here.. http://teamkassanova.webs.com/k2page1.htm . I had alot of problems with that version and so its time fore a complete redesign.

My goal is to create a buggy which is more durable , has the lowest center of gravity of any 2wd buggy, and to make it handle as good or better than the other factory buggies. Secondary goals include getting it into a magazine and having it be raced at the Ifmar worlds. (Shooting high)

The rear will be made with a Team Magic E4 drive train and suspension mounts along with custom delrin a-arms and ntc3 rear hub carriers. I will be adding a custom slipper clutch in there too. The reason behind the team associated ntc3 hub carriers is for pure durability. My buggy will probably end up being heavier than the others but it will break less and with the new lipo and brushless technology it shouldn't be a huge deal.

Their is a possiblty the I might start by making a simple version first by just using the stock B4 suspension parts and stand up shocks to see how this electronics layout does. But it hasn't been decided wither I will take smaller steps or just go all out.

The chassis will be made out of carbon fiber and have horizontal saddle packs. I am going to be trying to use screws thru-out the whole buggy with the same hex size so I will only have to use one or two wrenchs on it.

Up front I will be using B4 steering and a Gt2 front chassis plate. I wanted to have my front a-arms be stronger than stock B4 a-arms so I will be making beefier custom delrin a-arms (lower and upper) and ntc3 front hub carriers also for durability.

The buggy will feature laydown shocks all around. I am choosing to use laydown shocks because they provide a lower center of gravity, added durability, and a progressive suspension. My current idea is to use revo shocks on the buggy to provide a smoother suspension on the big jumps because of there larger diameter. They may end up being too long though.. in which case I may have to use touring car shocks.

The receiver and esc will be mounted behind the rear axle in a battery box to provide some weight to the rear and to keep all the electronics down the center. They may also be mounted on each side of the chassis.

I also have a highly top-secret innovation I will be using on this buggy.


Here is a Cad drawing I did just to get an idea of spacing and of how it will look and such. The cad drawing definatly isn't done and I will probably just start making actual progress on the buggy instead of finishing the cad drawing. So far I have alot of B4 parts left over from the K2 v1 and have the Nitro Tc3 hubs and Gt2 front plate..and I got a great deal on the E4 parts so those should be here soon and I can start working on drawing up the chassis.

Another awesome project. I took a look through your webpage too and out of curiousity, what were the problems you faced with your previous prototype? It did look very good!

Hey, good luck with this one, I was following the build of your previous car and wondered recently what you were up to now.
You should finish the CAD drawing first, much better testing all the suspension and drivetrain on the computer than half building it and finding it doesn't work, then having to go back and remake new parts because they need changes.

Look awesome !

Well when testing I had alot of different problems with it. Suspension wasn't set-correctly..the geometry made even the stiffest touring car springs feel like mush. Alot of the problems came in the drivetrain.. the rear of the chassis was too flexible creating gear mesh problems and the cvds kept popping out.

Well recently I have been working on a Traxxas 1/8th buggy. Found here..http://teamkassanova.webs.com/evo8.htm I also have been moving a quiet abit . But I have finally settled down and found a job to fund my projects.

I have been teaching myself Solidworks and so its been a trial and error type of thing I haven't grasped the advanced skills to draw a complete car and do tests on it..with my Cad skill level I find it more effective personally to get into the workshop and do trial and error by building.


I received the Revo/Slayer shocks today. I got a good deal on them on ebay only $13 shipped for 4 slightly used shocks.

In version 1 I had a hard time setting up the suspension with the touring car shocks. I'm not sure they where up to the task of offroad car.

I picked Revo shocks because of there large diameter (14mm) and spring selection. Traxxas offers springs for the Revo shocks made for the Revo, Slayer , and Jato. The Revo shocks obviously being the stiffest and the Jato ones being the softest. These are a bit heavier than the stock B4 shocks but not too much. If weight becomes an issue I can always get the plastic Jato shocks.

Here are some comparison pictures. On the far right are B4 shocks, middle are the Revo shocks, and the far left are touring car shocks I used on version one. I may resort back to the touring car shocks if the revo shocks are too heavy or big. But I think the added diameter and new spring choices will help a ton.

A good choice of shocks would be the ones from the Yokomo Bmax4, check them out!

Hmm I will have to look into those.

Got the E4 parts today. I got an amazing deal for $55 shipped. I just have to get a rear E4 diff for it though. The e4 rear end is going to work great on this. The width of the hinge pins is slightly less than the B4. I was able to fit stock b4 a-arms on but the spur gear would hit the front of the a-arm with out modification so it looks like I will definatly have to make new a-arms. I was worried that I would have to make the wheelbase longer because of the lack of the room for the saddle pack but it looks like their will be plenty of room. I'm going to start drawing up the chassis and then I'll make a mock up chassis before I cut it out of some nice carbon. I feel like I almost need to figure out how to make a slipper clutch for this to get that out of the way though becuase thats one of the major hurdles I have to clear. I'll see what I can master mind.

After getting the E4 aluminum parts I have the feeling this is going to end up a sort of "luxury" buggy .
Here are some pictures..

The slipper will be a big issue !
