This is the MSH Protos helicopter from M.S. Helis with the Carbon Fiber Frames. Lightweight & quiet, its superb Italian engineering gives this new 500 size electric heli incredible performance & agility. The innovative single belt design provides a continuous drive from the motor to the main gear and the tail rotor eliminating gear mesh problems and noise resulting in smoother and quieter flight. Its low weight, rigid frame, and smooth slop free controls make the Protos fast, nimble, and precise. It can be flown on 4S up to 6S battery packs with incredible performance and agility. Weighing up to 200 grams less than comparable 500 sized (425mm rotor blade) helicopters the Protos can weigh as little as 1520 grams with a lightweight 6s 2500mAh setup. The frames accept Mini size servos using either single or dual mounting holes and the tail grips are balanced with integrated Chinese weights so even with a mini size tail servo can have the same performance as a full size tail servo. With its programmable paddles and several mixing options on the head to tailor control response, the Protos can be fine tuned from mild to wild. The Protos is different in both look and function, and is exciting to fly.
