The MSH Protos brand by MS Heli of Italy is known and respected throughout the radio controlled industry for its high-quality RC helicopter kits and parts. Currently the MSH brand consists of only the very popular Protos 500 line of RC helicopters.
They are known throughout the industry as being beautifully designed stable flyers. With the capacity for stable setups for beginners, more advanced setups for sport flight, and extreme setups for 3D / competitive flight, the kits are a very nice choice for almost any radio controlled heli enthusiast.
The Protos 500 features a unique belt configuration that drives the main and tail blades with no gear mesh. This innovative design keeps the platform very quiet in flight, virtually eliminating noise with the exception of the hum of the brushless outrunner motor and sound of the blades whipping through the air.
