I choose to use the Align governor on all my nitro helicopters for several reasons. It has a very compact device measuring 28.5mm by 26.2mm by 9mm.

 The Align governor is one of the easiest to program governors on the market and its performance is quite good, better than most other governors. It is also very light weighing 10 grams with wires and very easy to install. Price is also an important factor, the Align governor is the least expensive of all governors currently available on the market.
