I had the exact same thing, and well it's is hardware problem with the Hobbywing. They removed a part they shouldn't have and causes the rpm signal to go nuts.

You can solder bridge 2 pads together.......currently looking for a pic, I used a jumper for testing, and well never removed it.

Or you can just get a Hobbywing rpm sensor and hook into your motor wires and run to your Neo to get rpm.

I bought 2 brand new HW130 opto's and had this exact same issue. Hobbywing tech support was useless and I never got a response on the issue. I fellow heli flyer told me about it and walked me through some testing and I installed the jumper and it worked as it was suppose to. I'll look for the pics and post.
