Good tank, but too airy.I've got 12 inches of 2 28 gauge wires with a 32 gauge Clapton outer winding after many tries, 12 inches is about 2.1 ohms, maybe it'll work. Problems with to much friction so I used rollers made from 3 sections of tubing, next is putting wheels on it. Also problems with the spools of wire that get stuck when unwinding, hopefully that will end.
The coils will be going on the TFV8 BBB, my favorite tank.
