While waiting for my Dubro hardware and other supplies to arrive, I killed some time goofing around with the included kit hardware. All of it seems OK to use in a .40 size model. But 1/4 scale? No way, IMHO.
The capacity of the included fuel tank is not listed, so I measured it. It holds ~18 ounces, or 575 milliliters.. I decided to examine the tank clunk and had to laugh at what I found in it.
