Yes, I now agree with the larger sized tanks being too much. While comparing the size of the 12, 14, and 16 ouncers; I decided on a 10 ounce. Those other were just way to big. I know on my T-Maxx the difference it makes from full to empty on the way it runs, I could only imagine what would happen in the air with more tank than the exhaust could fill. So do you guys think I made the right choice with the 10? And thanks again for all the great help. I hope that soon in the future I can return the favor.
