Notes

The Big Rock is ARRMA's 1/10 3S crew-cab monster truck. The file is a 514 × 328 × 201 mm envelope; the length comes from Big Squid RC's spec list because the ARRMA page lists 327 mm, which is the wheelbase.
Wheel hex and track are not published on these pages.
True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
