Worked on the cable steering tonight. I don't have enough cable to make the actual setup but I really wanted to make sure it was doable so I just cut in half what I had and started messing around.


I made a bracket to attach to the sliding bar via two holes that were already in the bar and of correct diameter:








Then I was trying to figure it out in my head but decided to draw it and see if it made sense. The idea is to solder metal tabs to the newly attached bar, and solder each cable to these tabs:









Just crimped in place, soaked in flux and ready for solder:











All soldered, now just need to find how to hold the sheat for the cables:













Out of plastic, I made a block with a slot for the bar, and holes for the sheat and cable. The idea was to drill half of the hole at sheat diameter, and the other half at wire diameter, but the plastic is too soft, so that one will only be a prototype (the block) and I will need to make something harder (probably out of aluminum):












And a small vid, I am just pulling and pushing on one of the cable while trying to hold the iphone at the same time lol

Hey guys, sorry for lack of updates, here is something new I got in the mail. Looks like it was made to be there So do you think I should leave it in?












Fits just right in with the ESC up front.. That's one thick looking radiator though lol Really tempted to use it, with the extra weight of the car, the torque will be welcome. (It is a Castle 3800kv 4 pole and I would use it with the 2s saddle pack)


Maybe you can help with a question I have, I also have a 4600kv 4 pole but it looks like it might be shorted, it is very hard to turn compared to the other one, very notchy, can almost not turn the shaft by hand when there is no pinion on it. I also made the test of shorting two wires and try to turn it by hand and it is not really harder to turn when you do, whereas with the known good 3800kv there is a huge difference between shorted wires and not shorted. Any of you guys have both motors and can compare them, see if the 4600 is way notchy compared to the 3800?




I also swapped the front springs for shorter and softer ones, from a CC-01. Sits a tad lower and closer to what it should now. Should be perfect once everything is on it.

Now you can make the radiator cut-out as needed on the RS 2000 aswell! LOL! Looks very nice as always. And i know that "did they made it to fit in here?"-feeling that you got when you installed it into the car

Thank you Lars I have been searching for the radiator cut out of the RS2000 but I am not quite sure what it is, do you have a picture?


Also, huge milestone last night! Steering works!















And also.... I ran it!!!




I completed my first working prototype of the steering, and I was about to just push it around on the floor with my foot and steer it, and it struck me, I can just put the motor and an ESC, duct tape the drive shaft and go for a ride!!! I thought I could not do that first run and not film it, I am trying to upload it as I type this, it is a pretty poor vid with not much space to go (cluttered garage!) but at least I got one!


There was only the driveshaft extension I made which is missing a setscrew but I wrapped some duct tape around and it held pretty good! No grip though on the garage floor.


Here is the vid, sorry about the quality! I put the MK1 body because I needed the front part off to put the clamp for the steering assembly and the MK1 happened to not have the front half bolted.


And I mistakenly recorded at 120 frames per second so I'll be able to edit the vid and slow it down without losing frame rate (that will be a second video upload later though).


Lol I love how the still picture of the video looks like it is doing a burnout lol






http://youtu.be/0lz-7sZus1A

A couple vids showing the steering :



http://youtu.be/8K6sm_GjXKo


http://youtu.be/usA6prXDIvA




First outside run. I promise sometime soon I will make a proper video where I will (try to) follow the car with the camera for now it is another vid with the iPhone sitting by itself on the ground lol And you don't see on the camera when I rolled it, you can hear it though!

I re-uploaded the first outside run video in HD, the first upload was really crappy quality, on that last one you can see much better how the suspension works! I think once the battery is at the final location (at the seats) it will handle very nicely!

Small update! I made a new front beam, the aluminum one was not far forward enough to bolt the skid plate to it, so I made one out of steel. It looks much nicer too, but quite heavier than the alu one, so I drilled some speed holes in it Might drill more on the part facing down to remove some more weight.











Now that I think of it I should have tried to do dimple holes to add strenght! Not sure how I would do that though I have never experimented with that.




I also cut the mock up steering cables at the servo to start and think of how I'll run these to the back where I want the servo. I think I will make them go through the firewall as low as possible (like the one on the right in that engine bay pic, just above frame rail), and run them near the door sills.







This is where I want the servo, with the servo arm poking up through the floor. It will have the two cables attached to the same servo horn hole, one coming from each door sill. Hopefully the added curves in the cable to get there do not induce too much steering slop or friction.




I'll have to think of a way to keep the servo clean (probably a rubber balloon?) given where it is. I don't pan to go through water but certainly some dirt!


I wanted to do more but got interrupted. At least I can now put the body on and have the steering bolted, without a big clamp up front lol!

Wow that was a long time without updates! We moved house this summer so did not have much time for hobby, but things have settled now and I have my new hobby area ready to continue It is a large area upstairs of the garage:





Sooo I have a small tiny wee update! I was able to make use of the new hobby space a bit tonight. No huge progress but I started to work on replacing the tiny steering cables I used for testing with actual length, desolder the cables, but then I could not find where I put the solder flux when moving...


So I moved on to other things I have been pushing for a while, and as suggested a long time ago by Lars I proceeded to replace the little m2 screws and bolts holding the chassis rails to floor with larger M3, threaded in the chassis rails. Don't need bolts anymore, and the button heads are inside the car, so they are flusher inside, and I ground the other end flush under the chassis. Nicer!







Then I found the flux paste so I was able to resume working on the steering. I cut the yellow sheat to correct lenght, and made mounts for the steering servo. Here is where I am at now, with the button head screws on the floor instead of bulky bolts and nuts, and ready to do the thingy that will tie the cables to servo horn. That might be tomorrow night

Last night I continued the steering in the rear (lol strange to say!) I made two blocks, with one small hole halfway through, size of the sheat, and another tiny hole going through just the size of the cable. This acts as a sheat stopper, so I had the cables arranged like this:










Then I prepared the soldering of the cable to a metal plate I can attach to the servo horn. I did not expect what happened next, maybe you can figure by looking how it is before soldering









.....















The metal plate soldered to the floor... lol :banghead: I ground the hole larger to make a bit more room.


My problem at the moment is the cable moves horizontally and the servo arm moves as a radius so it moves up and down throughout the travel... The cables won't flex to follow this so I need to find a way to have the servo horn.

Hey there thanks for your nice comment! I did not quite keep this thread up to speed with the build, here are the last updates, I am copying them from another thread, the timing might sound funny but that will get you up to speed


I finished the steering tonight! That's a good news, I was all excited to try it out, I had put back everything in, ESC, receiver, taped the battery and the body on etc.. Getting the iphone ready for a quick vid, first pull of the trigger, the car moves like 1 inch and the esc cuts because the battery is dead.. AARRRGGG!!! lol


I had the time to snap a couple pics and a small steering video before the iphone battery also died lol I am uploading them and will post them shortly.


More exciting video coming tomorrow By the way you will notice the front looks much lower because I removed the 10mm springs spacers up front, need to put back like 5mm of lift.

Made a vid in the garage, it is painted plywood so it slips wayy to much... kind of hard to have the suspension work when there is no grip. It is quite a handful to drive lol especially since the place is not all that big, can't get much speed before hit something lol




http://youtu.be/ruwZTBvJa3c


Oh and the bumpers are not there anymore since I hit something and they fell all three lol they were held with a dot of hot glue each so.. yeah

I did another vid this morning, slow motion of the suspension when dropping the car on the table from a few inches. Probably need to replace the pistons in the rear shocks for a bit more damping, and also the rear axle linkage touches the steering servo so it kind of bottoms out weirdly, but otherwise pretty good!

Did some practice tonight, I'm getting better at keeping the car in control, placed the battery for 50-50 weight distribution, and played with different tires. Ended up with the same tamiya rally tires in the rear but with a different kind of threaded rally tires up front, so the car won't suddenly switch from oversteer to understeer. But what helped most is the throttle EPA (limitation) and the throttle exponential which I cranked all the way down (for a slower throttle response on the trigger). Makes for easier modulation of throttle and avoid unnecessarily high rev.











Also I'm getting ready to try out the 2S lipo saddle pack :crazy: the sweet spot for weight distribution is just in front of the rear suspension 4-link boxes, so one saddle on each side of the driveshaft tunnel. That makes for about 50-50 or just a tad front bias. That's cool they are that far back, I was afraid the best position for accurate weight distribution would interfere with eventual seats...

I did not do much progress lately, but I do take it out from time to time for a spin (I think that's the right word lol!)

I accidentally went over an angled cardboard and was surprised how easy it climbed right up! So I did it a few more times on a video

I got the car to my office where we have a precision scale and it now weigh in at 4.3 lbs, functional with battery and all. Also there are larger areas of carpet at the office, more grip and speed which is scary in a tight corridor with this car since it currently has pretty soft suspension and higher CG!

Also removed the oil from the front struts as it was way too thick, makes more sense now but slightly bouncy lol will have to find lighter oil. Made a small vid too, tried to follow the car with the iPhone while at the same time driving the car... I am getting pretty good at driving it but with the camera the skillz dropped significantly lol ! Look away a split second and the tail is gone! I was able to catch a few nice beginning of slides in slo motion though. I took a couple of new pics of the chassis too.




http://youtu.be/uR02PfzYzxg















Now I am thinking of doing a roll cage but unsure how. I have brake line and a bender, but only have stuff for soldering, no brazing. Might give it a go since it is not going to be abused like a rock crawler, should hold pretty good. Searched for some reference pictures to have ideas:

Last night I made the front fender thingy, the rounded part that protrudes inside the car and allows the wheels to turn. So I have one less hole in the floor now!

Started with a brake cleaner bottle:







Fits almost directly! Needed to trim the hole just a little bit. Also the can has some kind of plastic coating inside, I burnt it off with the torch, also burnt the paint and it was all very easy to buff off the remains after that.









Then the real work started:










Held in place with a clip:












And soldered (I drilled two holes for M2 screws to hold it in place secure while soldering, then removed the screws):









Clears the small wheels good:








And clears the larger wheels just fine too!









All in all still ugly soldering but it seems to hold good, and I might put some JB weld when all done before painting to hide whatever is not nice enough.

I made the second side last night, went pretty good and the result looks better than the first so I guess I am improving somewhat

Nice to not have holes in there anymore! Next is to do rear wheels tubs from similar material. Sorry for another set of pics looking almost the same lol!!

Ready to solder:
