Do I need any special tools to install this drive gear?

Installation typically requires standard hobby tools and correct gearbox shims. A small press or soft mallet can help seat the gear if needed, but no specialised tools are required.

Is the 16T option better for technical tracks?

A 16T drive gear favours a balanced setup, offering usable acceleration for technical sections while still allowing reasonable top speed on faster straights.
