Posted October 13, 201410 yr After watching a 4.5 hour documentary on rally racing, I think it's time I build my own rally car. The front suspension is already complete: a front McPherson strut system measuring only 15 studs wide (not counting the wheels). Next up: rear trailing arm suspension!

October 14, 201410 yr Author Thats looking really sweet! How well does that setup return to center? Really well. I use this setup in most of my models.
October 14, 201410 yr Really well. I use this setup in most of my models. Ahh cool! How well does the M motor stand up over time?
October 14, 201410 yr Author Ahh cool! How well does the M motor stand up over time? Same as any old M Motor
October 14, 201410 yr That's this one, they have been used in some NHL hockey sets. They're expensive without comparison, but I managed to get five of them in 4 colours, for only € 2,95 on a German Ebay Listing (...). They're useful, I use them to keep the steer of a motorcycle-MOC straight.
October 14, 201410 yr I suggest you to use servo motor, because M motor will stall and eat up lots of power from the drive motors.
October 14, 201410 yr Im really curious what era Rally car your headed towards, given what we can see I'm guessing late 70s early 80s, just before the onset of 4WD, and AWD cars. (I only guess that based on the lack of power able to go to the front wheels)
October 14, 201410 yr Author How are you going to set up the rear suspension? Hope this answers your question: Got the rear swing arm suspension in place. It's only 13 studs wide (15 with the wheel mounts) and it has a limited slip differential. The final gearing is 1:1.5. I suggest you to use servo motor, because M motor will stall and eat up lots of power from the drive motors. Only one problem with that: I don't own a servo motor (and don't have money to buy one).

(I only guess that based on the lack of power able to go to the front wheels) I'm going for an old Datsun 1600 SSS rally car, based on this:
October 14, 201410 yr Author Looks good. I hope you use buggy motors I'm not sure I can fit them in, but I'll look into it.
October 14, 201410 yr Really well. I use this setup in most of my models. Didn't some genius make a list of most accurate return-to-center modules (all approx. the size of the hockey spring) and determine the hockey spring the least accurate?
October 14, 201410 yr Cant wait to see how this shapes up. Nice work so far. I would love to see your front hubs. Any chance of an image without the wheels? (The rear suspension from below would also be great!) -ED-
October 14, 201410 yr I also have a good Macpherson strut setup, good for rally cars. I might post later. This looks really promising so far!
October 14, 201410 yr Interesting. I like the two M motor set up for drive I must try that myself. Look forward to the completed model. H
October 15, 201410 yr Author For those of you asking for more detailed pictures: Rally WIP 3 by VKTechnic, on Flickr Didn't some genius make a list of most accurate return-to-center modules (all approx. the size of the hockey spring) and determine the hockey spring the least accurate? Sheepo had a writeup a while back on some alternative return-to-center mechanisms. The reason I use the hockey spring is it's compactness - it's the smallest solution by volume. I would love to see how you accomplished the LSD. tim I connected the differential housing to a clutch gear tied to one of the outputs, like Efferman did here: x-ray by efferman, on Flickr
October 15, 201410 yr 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...
