Bought the HGLRC Specter 1-2S 10A SPI AIO for a 2.5" analog build.
Quick and easy to get setup and in the air compared to my previous freestyle builds. Quad flew pretty good with stock tune, but about two days in video started dropping on every channel, even on the bench in the same room. Tried various different antennas and second quad on the same goggles was rock solid, so it pretty sure it wasn’t my setup. Found a review on a different site reporting similar issues. I submitted a warranty claim on 10/5/26 and haven’t heard back. I’ve ordered a replacement from WREKD since the rest of the board was so good. Will update this review when the claim is resolved.
