Here is a handy TOOL and extra informatino below. CHOOSING THE CORRECT SERVO - FAQ Size- What space do I have? The size of the modal and the servo mounting dimensions can dictate the servo that you choose. There are a few different footprint classes (JUMBO, STANDARD, MINI and MICRO) and depths so there should be a servo to fit your needs. Torque- What is the size and weight of the control surface that you are moving? The bigger and heavier the control surface on the model, the higher the servo torque needed. What is the length of the servo I am using? The longer the servo arm used the higher the servo torque needs to be to compensate. Speed- Do you require a very fast response to make frequent corrections or have instantaneous throttle response? A fast or slow servo will alter the 'feel', it's similar to having positive or negative exponential set on your transmitter. Voltage- What battery voltage are you using? All servos can be used with 6 volt DC supply. If you want to use the newest 2S LiPo receiver batteries you will need to choose the 7.4volt compatible servos. These servos can also be used with lower voltages but the performance will be lower. Gear Train Material- Is this a large or powerful model? Will the model be used aggressively or with sudden high impact - more info on request.
