The BX-240-4 is exactly the flat four twin that so many have waited for. It is now at last possible to build 33% to 40% scale models powered by a 4-cylinder four stroke engine.
The Kolm BX-240-4 is ideal for all models up to 35 kilos (77 lbs) in weight and with the optional electric starter leaves nothing to be desired.
