Zerobricks Posted February 12, 2014 Posted February 12, 2014 (edited) A test chassis with 4 RC motors, 2 RC units, all wheel drive, all wheel steering and suspension. Works....meh meh....Its fast, but steering radius is a bit high. Also the CV joints are very unreliable and tend to pop out. I think a simpler, lighter model with only 1 RC unit and rear wheel drive is better. If anyone is interested here is how the chassis looks like: And a partially finished LDD model: http://www.brickshelf.com/gallery/zblj/Trial/halo.lxf Edited February 12, 2014 by Zblj Quote
Black-Build Posted February 12, 2014 Posted February 12, 2014 Looks cool, wheelbase a little bit too long but completely understandable if you have two RC-units. About the steering, can't you use servo's or gear up in the chassis? In that case you'll have to place the units two studs up. Whats the gear ratio, 3:1 ? Quote
SNIPE Posted February 12, 2014 Posted February 12, 2014 (edited) EPICNESS But why 2 RC units? Edited February 12, 2014 by SNIPE Quote
Black-Build Posted February 12, 2014 Posted February 12, 2014 (edited) The car only has 2 motors? It has two in the front and two in the back... Edited February 12, 2014 by Black-Build Quote
SNIPE Posted February 12, 2014 Posted February 12, 2014 (edited) Ohh, Sorry I was looking at the .lxf Wont one motor rotate the opposite way as the one opposite to it? say one rear opposite to the other rear Edited February 12, 2014 by SNIPE Quote
Zerobricks Posted February 12, 2014 Author Posted February 12, 2014 Ohh, Sorry I was looking at the .lxf Wont one motor rotate the opposite way as the one opposite to it? say one rear opposite to the other rear You can easily switch the polarity on he old 9V system by rotating the bricks with wires 180 degrees. I already drove this thing, you know :) Quote
SNIPE Posted February 12, 2014 Posted February 12, 2014 (edited) Oh right, shame PF cant do this. I haven't used 9v in years i'm trying to make a simpler/lighter version in LDD Edited February 12, 2014 by SNIPE Quote
pluto7443 Posted February 13, 2014 Posted February 13, 2014 Oh right, shame PF cant do this. I haven't used 9v in years i'm trying to make a simpler/lighter version in LDD You can in PF...Just use a switch. It works, but it does add another wire Quote
z3_2drive Posted February 13, 2014 Posted February 13, 2014 Yeah at this scale practicality is the only issue, that's why I stick to RWD and no CV joints. (except the 8880 style, which I am currently figuring a way to implement) Quote
