Oh yeah, Don't get me wrong. There's no question that a good pumped smoke system on a gasser is hands down the way to go!! I was just trying to amswer the question that was posted, which was how could he put smoke on his Trainer? So I answer his question the best I could with the only system I know of that will produce some smoke with a small glow engine & still fit in the smaller size fuses of the Trainers. Obviously not the top of the line smoke system, just an inexpensive alternative that can be used in a Trainer, that's all. Personally I never bothered to try to smoke any of my Trainers. I used them for what they were designed to do, teach me to fly RC.
