Very cool Coast Guard HH-60J Jayhawk
This thing is huge! A small child could ride in the cockpit, no problem… although probably not recommended
Turbine powered 1:6 scale Eurocopter EC 135.
This might be the largest, but I’ve seen others that come pretty close. In any case, it sounds like a real heli to me once he gets it spun up and flying.
Does anyone remember Magnum PI? I always thought this was the coolest helicopter. Now anyone can have one, almost!
