Default Resin Gear or Metal Gear

Where possible and practicle, I use non-metal gears. I flew glo for 25 years. The last 2 years I moved to large scale gas and am learning all about metal geared servos and their wear patterns. The gas engines shake, and the servos are one of the weak llinks so to speak. The digitals are not an exception as they fight to stay where they are and consequently neutral is where the pattern is most pronounced. There are those in large scale that will still fly up to 35% planes with the JR 4721 with good results. I have never done that, but there are many here who do. Long answer short, depending on your plane and set up, non metal gear should be fine_bob

I like most prefer nylon gear trains, they hold up much better over time. BUT (there's always a BUT) as Bob mentioned the metal gears do not withstand the rigors of use as well as there nylon cousins, BUT we use the metal geared servos for there robust ability to withstand the flight loads imposed on Giant Scale models. With a 1/4 scale model you most likely go either way.

Metal.

I have had nylon gears fail (read, stripped the teeth off the gears) under flight loads on much smaller craft. I have yet to have a metal gear lose any teeth on any model.
