VKTechnic Posted October 15, 2014 Author Posted October 15, 2014 Are the rear wheels rolling ok? The CV joint axle piece is held only by one stud hole... Funny, when I build, I discard such great ideas (if I got'em ofcourse :-)), because of prejudice, that this sure cannot work... They're rolling fine, very little wobbling. Only problem I'm having so far is the 2L axle connecting the gear to the CV joint is getting pulled out during rapid suspension compression/decompression. Working on a fix for that now Quote
Doc_Brown Posted October 16, 2014 Posted October 16, 2014 You don't have any problem running 2 M motors? I'm guessing you must be using a V1 not V2? I found L motors only worked on V2 on the same channel. Quote

Technyk32231 Posted October 16, 2014 Posted October 16, 2014 I have a very similar Macpherson strut setup. In mine, I use a #3 angle connected oriented vertically, so that one end is attached to lower control arm and other end has an axle for the spring. Quote
z3_2drive Posted October 16, 2014 Posted October 16, 2014 Love the design! Independent trailing arms are great but I don't know if they would work on a large scale with multiple buggy motors. At this scale it looks like it'll go great :) What do you plan for the body? Panels/flex axles/tubular/studded? Quote

Might try printing some decals to make it look more like a rally car Quote
VKTechnic Posted October 16, 2014 Author Posted October 16, 2014 Just finished rebuilding the rear axle for three reasons: 1) durability, 2) better weight distribution, and 3) I wanted to use a buggy motor. Rally WIP 4 by VKTechnic, on Flickr Next up is bodywork :) Quote
PROlego Posted October 16, 2014 Posted October 16, 2014 So you don't have money for a servo but have for the lipo battery :P ?? Quote

Thirdwigg Posted October 16, 2014 Posted October 16, 2014 So many techniques used here that I love to use myself. The longitudinal differential with clutch and the CV joints as wheel mounts work so well. Glad to see you added the buggy motor. That rear set up is a space utilization work of art. Quote
AndyCW Posted October 16, 2014 Posted October 16, 2014 I also really like that rear end setup, but am skeptical that it can withstand the power of a buggy motor. Sudden direction changes will result in suspension movement. The 3l axle will retreat into the cv part and only engage half of the 12t db. This in addition to the bearing surface of 1 stud will allow the gears to come out of mesh. Trapping axles is also important. They tend to "walk" out when exposed to high rpm. You always seem to pull it off though, so I'll wait and see. I'm sure it will look great when it is done. v/r Andy Quote
VKTechnic Posted October 17, 2014 Author Posted October 17, 2014 Spent a few hours working on the 7th rear axle design, and I'm still not satisfied. Rally WIP 5 by VKTechnic, on Flickr I've finally improved the suspension stiffness, but the RC motor stalls much too easily (even with the least amount of gearing possible). It probably has something to do with the receiver, so I may abandon the RC motor and switch to some L-Motors. Oh, and I started mocking up some of the bodywork. Quote
VKTechnic Posted October 18, 2014 Author Posted October 18, 2014 Finally found a rear axle that I'm mostly satisfied with. Rally WIP 6 by VKTechnic, on Flickr Only problem is it's a tad slow, but that's not a big issue. Now I can finally move on to the bodywork Quote
VKTechnic Posted October 20, 2014 Author Posted October 20, 2014 Starting to look like an actual car now Rally WIP 7 by VKTechnic, on Flickr Front end could use some work though... Quote

Technyk32231 Posted October 21, 2014 Posted October 21, 2014 I think the wheels stick out a little too far from the body. Other than that, it looks great so far. Quote
VKTechnic Posted October 21, 2014 Author Posted October 21, 2014 I think the wheels stick out a little too far from the body. Other than that, it looks great so far. They do, but I can't change much about that with the current suspension setup. FYI they used to be 1L closer in on each side, but the rear suspension was horrible. Quote
Technyk32231 Posted October 21, 2014 Posted October 21, 2014 Or maybe make the middle wider, and then have the sides angle in towards the front. Quote
Doc_Brown Posted October 21, 2014 Posted October 21, 2014 Add black wheel arches! Would make it look sweet. Great job tho! Quote
zweihander Posted October 21, 2014 Posted October 21, 2014 I think a you can make this into a Lancia Delta with some work. Plus, the wide wheels would be spot on! Quote
Nalyd997 Posted October 21, 2014 Posted October 21, 2014 I think a you can make this into a Lancia Delta with some work. Plus, the wide wheels would be spot on! Yeah but he said he is going for a datsun Quote
zweihander Posted October 21, 2014 Posted October 21, 2014 Yeah but he said he is going for a datsun Hmm, I must have missed that post. In that case, it looks good :) Quote
Black-Build Posted October 21, 2014 Posted October 21, 2014 It looks very different than I was expecting, but it is still a nice car! Quote
VKTechnic Posted October 25, 2014 Author Posted October 25, 2014 Front end is pretty much done, rear end could still use some work... wip08 by VKTechnic, on Flickr I also did an off-road test,and this car doesn't perform too well on anything besides flat ground. Fixing that would require rebuilding the rear half of the car, and considering that the car runs fine on flat ground, I think I'll keep it the way it is. Maybe next time... Quote
