Understanding Gear Ratios: Different gear ratios change how the power is applied to the air. As the letter gets further away from "A" (more and more gear reduction) the RPM and pitch speed is reduced and the static thrust (and usually prop diameter) is increased. In other words the prop shaft will turn slower but with more torque so it can handle larger props. If the pitch speed does not exceed the stall speed you can't pull the model fast enough to make it fly. You usually want pitch speed to be at least 2-2.5 X stall speed for slow fliers, trainers and 3D models. Sport aerobatic models 2.5-3X stall speed, pattern airplanes at least 3X stall speed. If your experimenting be sure to get a range of props for the motor. In many instances one prop will make the model feel poor while another prop might exceed your expectations. Nobody can predict what will work best for you so get what you think will work and a couple nearby props so your not missing out on better performance. Look in props section for simple math to calculate pitch speed if prop pitch and RPM are known.

GWS IPS Dual Motor - RXC Power System-S2 - Product Image

GWS IPS Dual Motor - RXC Power System-S2

The RXC version of this motor system has the 7.2V motor and is intended for use with 6-8 cell NiMH, NiCad or 2 Cell Lipo battery packs. Follow GWS prop selection recommendations to keep amps at 2 or less for best life out of these systems. This is the same motor as the famous IPS drive just in a lighter weight gearbox. We suggest you order an extra shaft or two in our GWS motor system parts section as the 2mm shaft can be bent in a crash easily.

GWS EPSD 350-A,B,C,D Dual Motor Power System - Product Image

GWS EPSD 350-A,B,C,D Dual Motor Power System

All of these power systems use the same motors at different gear ratios. GWS shows setup loads from 16 to 25.3 amps.The quality is high in these powerful motors. They perform best on 7 or 8 cell KAN1050 NiMh or RRC 2x2000 SHD Lithium Polymer packs. 2 Cell Lipo packs are possible also with prop size adjustments. Remember, the higher the ratio the greater the static thrust at a lower speed. Choose wisely. By purchasing a few different props you'll be able to make adjustments to static, inflight thrust and pitch speed of your power system and come up with the best combination of performance for your bird.
