Thanks
We did a little experimenting last weekend at Miss Afterburner and discovered that when using 2 of the 3/16" diameter "Super Stick" injectors, the smoke oil came out in solid streams. When we used just 1 injector, the oil came out in a nice spray (better for producing smoke).

We didn't test with the smaller "standard" injectors but I'm pretty sure 2 would both "spray" and work better than 1.

We also noticed that results varied depending on whether the injectors were in front of the thrust tube (generally better smoke), or behind/no thrust tube at all (i.e. KingCat type turbine mounting). Your results may vary.

FWIW, I'm using just 1 Super Stick injector and my smoke is VERY thick using both SuperDri and Kynetic.
