Front end suspension components have been reworked to accept M2 hardware, and also made to allow some adjustment to caster up front.
I believe the M1.6 would have been completely sufficient, and i am keeping the components in Fusion to revert back for any reason, but i wanted to streamline the required bill of materials to be all M2 hardware. (except the M3x30 partially threaded screw which acts as the idler/jack shaft.)
Ran so many tests trying to get the most consistent prints for rod ends, though i could probably reduce speed below normal and a few other printed settings, the rod ends arent going to work correctly with the "height" where the ball stud sits being as tall as the flat spots on the part with the threads. i had initially had the flat spots specifically so it would all be flat on the print bed. but now with increased size for m2 hardware, there is a 0.25m difference, and if i shrunk up the flat spot, it is going to be severely reduced strength, and prone to stretching when screwing in the "turnbuckles".
Parts printed and ready to install:
in changing the rod ends to the M2 version, they got a bit bigger around where the ball pops in, now before explained in a previous post, i had the issue with the ball studs from the WLtoys, the shank before the threads was also bigger, so i had to change the servo horn stud holes from M2, to M1.4 (from an
scx24). did also have to shorten the threaded portion of the ballstud so they wouldn't hit the a-arms as
scx24 studs are approximately 4mm, and the WLtoys ones were about 2.5mm.
as the servo was out anyways, decided to shorten the servo wire (didnt need 3 miles of wire underneath the body) as well as use some liquid tape as some of the wires were fraying from constantly installing and removing over and over again.
Installed:
you can kind of tell in the picture but Christmas came early compliments to the wife and we got new wheels!!
they are 22mm so the front shock to tire at full lock clearance issue is back on the table.
also going to have to raise the shock tower back up approx 1mm, maybe 1.5mm.
I am introducing spacers for the bottom arms instead of relying on a screw for the adjustment to try to make them more consistent. eventually I'm going to add more sizes for preset different track widths.
That said, with that adjustment for the front i still need to try to re-visit the rear. have an idea to kind of "cheat" the clearances to the extended length rear spool shaft. not as desirable and eventually i believe i am just going to opt for adjustable driveshafts as in the Drift art kit.
