I have two of the Brison 2.4s and one Brison 3.2. A flying buddy of mine has the Fuji. There is no comparison between the two as far as I can tell. The little Fuji is much harder to start but runs very well once it gets going. Swings a 16/8 prop well and he powers a World models clipped wing cub with it in a scale like fashion. My Brison 2.4 starts usually on the 3rd flip and swings a 20/8 prop hard enough to hover a Hyde Cap X at roughly half throttle. The cap is heavier then his cub but I can't tell you the specifics. The Fuji is much easier on fuel though and both are easier on fuel then a glow motor. If you are looking for scale power & can get a good price on the Fuji, go with that. If you want more *^$@s go with the Brison. One thing though, the Fuji is a complete package, with muffler. With the Brison you get engine and ignition. The muffler is additional.
