Just did a test run from KGPM towards Bishop 76T. Was flying at 1200ft and getting 38-42 FPS until 1nm from Bishop when it dropped to 2FPS almost instantly. I let it fly straight towards Fortworth Alliance airport and the FPS jumped back at 2 nm past Bishop. Looks like a blackhole and this is very rural and sparsely populated, only scrub and bushes. This somewhere I would never have thought of flying so it did not bother me but it must be in other places and needs fixing. I actually liked the look of the area and will fly there more often.
