Received and installed in aircraft. AI is unstable and noisy. Contacted Aircraft Spruce for replacement on warranty but was told it can take weeks for settlement and Im forced to purchase a second one in the meantime.

Looked brand new, fast shipping, all the return postage for the core was in the box ready to go. So far the gyro works great!
