I like the fact that the smoke units are all on the chassis, that does ease the servicing when necessary, and we all know that smoke units need servicing!
I wondered about that oblong funnel too - as opposed to heat- and solvent-proof tubing and a couple of elbow joints. But maybe there isn’t space for the kind of contraption I’ve built to get smoke output at a little distance from the smoke unit. At the risk of creating a joke at my own expense, here’s an example:
All the tubing and joints come from US Plastics and are really intended for small fuel and lubricant lines.
Totally agree with GRJ about the chassis mounting of the smoke units.
