Harigo, I have not smoked a BGX but I have smoked an OS 160FX with the same exact muffler and pump you have and it smoked like a freight train. I would think the BGX would smoke even better.

Beware of the Slimline Showtime pump it is very hard to keep primed. Make sure you prime the pump on the ground before every flight because for some reason they dont like to prime in the air. Also they seem to work very intermitant. Sometimes they pump sometimes they don't. I have seen three of these pumps at our field and all three had the same problem. Also they tend to develop leaks in the pump. Keep an eye on your pump so as not to soak your plane with smoke fluid. I ended up taking my pump back to the LHS for a refund I got so discusted with it. Maybe Slimline has got these pumps working better now the three I saw were all purchased when they first became available on the market.

I have used Bennetts, Super Dry, and Powermaster smoke fluids and they all seem to work about the same. The Super Dry seems to be the cleanest of the three. It doesn't leave as much residue on the bottom of the planes as the other two.

Good luck and happy smokin!
