Well it looks like I got ripped off. Won a Heng Long Walker Bulldog on fleaBay on 4/1, the problem is the seller changed the description with about 3 hours left to state the controller and battery cover are missing.
I haven't cracked the thing open yet to see what's in there but does anyone have any experience converting these things to use a different controller?
Don't know if this will make a difference but it is the smoke and sound version.
Of course I was instantly curious and had to waste some more time looking into the thing. $1300 later I find myself patiently waiting the 4-5 week lead time MakerBot needs to build the kit and ship it out.
With a 1.7mm filament I'm guessing the part resolution will be in the 1-1.2mm range which is no where near fine enough for gears, but for custom suspension arms, shock/suspension/body mounts, and diff housings, I think it should work (although there will probably be some finishing work.)
First project will be a water cooling boxes to RTV over a car ESC heatsink (XP SC-450BL and Traxxas VXL-3s to be specific) so I can use them in the boats and not have the thing thermal.
