The Protos 500 by MS Heli of Italy is a 500-class electric remote control helicopter kit.  Since its inception the Protos 500 has undergone an array of make overs.  Originally constructed as a pod-and-boom configuration with an all plastic main frame the most notable feature of the heli was its use of a single-belt drive-system with no gear-to-gear mesh.  The belt was designed to transfer power from the pinion, with built in one-way bearing, to the main gear/rotor shaft and then to the tail rotor drive system.  The absence of the gear-to-gear mesh in the drive system gave the Protos 500 a unique sound with an overall quiet noise footprint.

Since its inception the most notable change to the Protos 500 has been the change from an all plastic main frame to a two-piece carbon fiber frame.  The resulting design made the frame a more ridged component within the overall design.  Originally offered as an upgrade, the new carbon plate frame-set has all but replaced the plastic one.

Other notable changes to the Protos 500 have been the addition of a stretch kit to the upgrade options that allow the 500 to swing 470mm blades, an increase from the stock 430mm blades.  The stretch kit includes a longer tail boom, longer belt, and of course a larger set of blades and is typically used in conjunction with a different motor/battery combination.

The stock Protos 500 is typically configured with a stock 880 Kv motor requiring a 4s-6s LiPo battery and a 60 Amp electronic speed controller.

Kits can be purchased directly from the company's website or through members of MS Heli's distributor network.
