Alladin,
Back to the subject at hand for a second, I really like having the smaller rechargeable driver for one very important reason. After I start my engine I put my chicken stick and the glow driver in my back pocket (don't put the driver in your front pocket with keys or change. They can and will short out and can catch fire). That way if I have an engine die on the runway, or a deadstick landing, I have what I need to restart the engine without having to haul the plane back to the pits and my flight box.
