Looking for gyro for.30 class hirobo.shuttle zx Installed an O.S. max .32 nitro engine. Tail rotor is very unstable. Suspect the gyro. Looked at amazon and saw this:

Mini Tail-Locked Single Axis Gyroscope Heading Lock Digital Gyro for RC Car Helicopter Modification Spare Parts. the brand is a XHSESA gyro.

Good? No good?
