It's a Lil (com) Bat from Black Hawk. The other (they come two to a box) flies nice with a Black Widow but could use more line tension. Launching and handling is a little awkward due to the shape/ planform. I fly over grass. I hope to fly the heck out of them tomorrow. The RC flying is banned for a couple days within a 30 mile radius of my house because the President is visiting the Air Force base about a mile from here.

I never did run it with the tank vent blocked. I've broken the engine in. My tank was foaming. I rotated it 90 degrees. I get nice steady performance in all practical attitudes holding it. I haven't been able to fly. We've been having 40-60 mph winds and snow.

Good to hear you've made progress with the engine. Some times fuel foaming will go away when you hold the model, but come back once you've released it. It's weird how some of the worst looking set ups work fine and then a decent looking tank install can have problems.

I originally thought someone was pulling my leg about the Armor All until I tried it. I had a Norvel Big Mig that wouldn't run out an ounce without leaning and dying. I suspected fuel foaming and tried the Armor All. It worked beautifully!!!

It makes things glossy with a thin coating of silicone oil, which acts as a defoamer. Not the greatest for plug elements but the practical effect is small - may accelerate deterioration of the element via deposits is all.

I've never understood why/how foaming would be a problem?
The clunk should stay in the fuel and if there is a little bit of bubbles or foam on top of that it shouldn't matter...
Air bubbles in the fuel line are more likely to come from vibrations of the tank, this can send the clunk up above the fuel level, thus sucking air.
