This BGX-1 is the engine of choice for those Giant Scale Modelers. The BGX-1
35cc Engine was designed as a lighter, more powerful, less vibration, and more
compact alternative to the converted chainsaw gasoline engines. One drawback;
fuel economy is better with the chainsaw engines, and fuel is less expensive.
The BGX-1 includes an engine mount that mounts to the firewall in the same bolt
pattern as the backplate-style engine mounts that come with SuperTigre's models
S2000, S2500, and S3000(K) engines. You can directly replace any of those
engines with the BGX-1 without redrilling your firewall.
This engine is covered under the O.S. 2-YEAR WARRANTY.
