The gantry was to work by building a framework, with rails constructed from 1x1 blocks. The gantry X/Y axis arms are to traverse the rails with wheels. There would then be some pistons for the z axis, a rotor, and finally a landing gear for grabbing. All pretty straightforward stuff. On something like this, you do not want suspension on the wheels:

agreed..but if money is an issue, I'd grab the $100 set of springs first then get the wheels. from experience in my trans am, springs/shocks/struts/whatever made a HUGE HUGE HUGE difference. I put vette wheels on and I just got wider tires which was sweet but i noticed a BIGGER difference from springs/shocks Well, my budget only allows for one at a time, and i'm just worried if I get springs ill have to just take guesses on wheel/tire sizes. I'm very unfamiliar with this kinda stuff as it is my first go. From what I am gathering the springs i'm planning on getting lower 1.5 - 1.75 im guessing the 1.75 is after they kinda break in over time. Not sure. However, the issue is knowing what tires to go with. If I have to chose 1.5 or 1.75 which is a better option? Keep in mind i'm most likely getting 15X7wheels, seems common enough and im not big on bigger size wheels, hell, i'm rocking 13's at the moment, steelies.. but 13's either way Also, I am not the fan of the "slammed" scene. I am more so into the flush look. Deleted wheel gap but not so over the top that negative camber makes my wheels look broken So from this information hopefully I can get some guidance with a tire size for 15X7 or maybe a slightly different recommendation based on the ride height adjustment soon to come. I also may consider 16's but 15's prefered. lets B-serious here tho, suspension first or else you'll be at stock hight or bounching around on these ebay special "coils", don't cheap out on tires like I see soooo many ppl do. lets B-serious here tho, suspension first or else you'll be at stock hight or bounching around on these ebay special "coils", don't cheap out on tires like I see soooo many ppl do.
1.0 out of 5 stars its as if it lost its ability to screw in its socket (it looks more like an issue with the socket and not the actual ... Hopefully this is an isolated case but my bike just broke after less than 4-5 hours of use spread across 3 days (normal park trails, no crazy mountain climbing). The right pedal just fell off while ridding and it won’t go back in, its as if it lost its ability to screw in its socket (it looks more like an issue with the socket and not the actual pedal).
