I contacted Flycomm (david?) and per his instructions, opened the Intercom box and got pictures for him. Instantly, he knew the problem. I had the wrong Patch cable.purchased a ga flycom to use in my dominator
I used my HALO several times in R22 with doors off and it was great. At home I trial-fit a Pyrotect full-face helmet over the HALO and it was comfortable. This is the setup I plan to use when the NANO gyro arrives,Not on the topic, but ... did anybody try HALO.
