Thought I would try something different from what I normally do since I just got myself a new printer. Since I can't solder and not much better at cutting the Brass to the right length I went straight to the Inventor. First I fitted a Piranha motor with slot-it gears and flag. I first went with the 15x10 CB Designs wheels and the big 22160FF PG tires.
It looked pretty good on the screen but then the issues started popping up when I printed it out. First I had it modeled up using 1/16 diameter roll cage but I couldn't get it to print out. So I changed that to 3/32 diameter with a base frame of 3/32 x 1/8. Wow, it printed but I forgot to check one small detail, the flag mount was to far to the rear and would allow the axle to pass. So I moved it forward and everything printed good.
It took a little over an hour to print and another hour to clean off the support and brim material. With everything looking good and the bare chassis in at 8.3 grams I sent it off to paint. Once the paint was dry I tossed in the piranha motor, gears, wheels, and tires oh my.
Oh yea, I couldn't resist, I put on 10" drums with rear spring detail and front suspension detail.
now it weighs in at 53 grams. so I couldn't resist and off to the track i went where it turned in some low 9 second laps as long as I could keep it on the track. The 10/27 gearing may have been a little much for this thing.
and now it will take some time but I'll start adding the RMS body to it.
I should be quite a challenge for me now to try and figure out how to add an interior to it while trying to keep the weight down.
After a little dremel work the fit looks to be ok but i check the fit tomorrow after doing some body work on the fender flares.
More later.
Oops the interior is set to high. No worries, I'll just lower the side rails that the interior is setting on, print it out a new chassis and try it again. That is one nice thing about those 3D printers, it doesn't make the Oops so bad. Maybe I could use the old Chassis in another slot that has the same 110 inch wheel base, then I can order more parts from SCC and get some more Dum Dum's.
