I'm flying on F-18 with my buddy on A-10C II. The problem we have is that my buddy can't see me on his HMD. He can see other players, can see friendly bots, but not me. I can see on my HMD everyone, including my friend. Sometimes I can see even enemy aircrafts. I don't know for sure which one us is doing something wrong. How I setup my Hornet's systems: 1. Press IFF, then `On/Off`. Got: `XP` on UFC and: 1 - 00 2 <nothing here> 3 C :4 A 2. Press `D/L` once, press `On/Off`. Got `ON ... 336.0` on UFC. 3. Press `D/L` again, press `On/Off`. Got `ON ... 127` on UFC. Got data from AWACS on SA-page & radar. 4. Turning on my HMD by rotating switch CW. As long as I can see him, but he can't see me I suggest that it's me doing something wrong. But I don't understand what. Is there something more I should do at startup?

How can I play on public servers with this Su-30 mod? When I'm trying to use dynamic spawn on any server it gives me an error "All slots are occupied". Even if Su-30 itself is presents as possible choice and there is no limit to spawn. I tried both CWS and non-CWS versions. At the same time there are no regular slots to spawn in old fashion. I have no issues to play locally or if I create a server by myself. But I can't find just a single public server, where I'm able to spawn in Su-30 (any modification of).
