Description:
The HS-5645MG is one of the best choices you can make for a 50cc sized plane for the cost. They will also work well in 30cc planes. It is fully programmable using Hi Tec's programmer. The combination of torque, speed, price and extreme holding power make it a favorite among pilots. Special alloy gears called “Alumite” offer tremendous strength yet are lightweight as well.

Power HD 1440A - Micro Servo - 0.8 kg (11.11 oz/in), .09/sec - 4.4g

The Power-HD DSM44 digital servo is a micro servo with digital control electronics for increased performance. Just like the Power-HD DSP33 ,the DSM44 is also very light and ranks as the secont lightest servo at RedwingRC- weighing only slightly over 6g!!! In the DSM44, the output shaft is supported by a ball bearing for decreased friction, and another great feature is that most of the gears are metal for increased durability! The lead is terminated with a Futaba-compatible standard “JR”-style connector. Servo horns and associated hardware are included.

It is important to note that stalling or back-driving this servo can strip its gears.
