buying Bell 206a with C18
I am looking at buying a 206A (low skid) normal cat, with a C18, other than the obvious fact that these are lower powered than the 20b how do they preform with 4 people and full fuel in Australian conditions? If I replace the engine with a 20b do I need to replace tail rotor or anything else? Do I have to replace the whole eng or just the compressor to get more hp. Thanks in advance
