Default Whistling Noise Resolved

During flight testing, around 130 to 140 kts, I would develop a high pitch whistling noises. Several builders suggested the canopy seal. After careful inspection, I found an area the seal wasn’t making good contact with the airframe. I replaced the forward seal and all whistling stopped. A small unsealed area will make a lot of noise.
