I would like to report that I have this Gyro (HM4000) in a sub-micro heli (probably the toughest environment a gyro could be in), It has about four hours of run time on it, also I have had to take a small amount of that time and trim it out, so the end result is: the gyro works well. Is it the best gyro out there? No, Does it suck for being an inexpensive piece? Absolutely not. It just works, it just takes some time to tune it.

My philosophy is: if one receives two duds, then one can bash the product. Been there and done it[sm=angel_smile.gif]
