Is it the Detrum GY192
? There's two around the same price point ... ?
I've got several rate gyros and they're great for taming gusts. But trying to track straight down a runway during takeoff - with a crosswind - you need more than a rate gyro. This is owing to constant nature of the wind on heading, versus a gust.
I'd like to play with a HH gyro to get arrow-straight takeoff runs, but didn't realize they had come down $O much!
More than you ever wanted to know about using a HH gyro to stabilize a takeoff run is here
