Nice overview! Might want to insert the actual images of the actual Rolls Royce RR-300 turbine engine. It is much simpler two stage free wheeling turbine engine with the centrifugal compressor. This is what helps makes the R-66 less expensive than others.
Someone's made a modification utilizing a military helicopter APU to replace the four-cylinder engine. The only other suitable turbine engines are proprietary designs by competitor used in their own helicopters
What !!!!is it o its a helicopter you must have said that a100 times my friend listening to your own narration is a good idea before you publish just a helpful hint
