This may be realistic and "works as expected" (I have no idea honestly but I'd rather ask than blindly accept it). That said, when I use AT Titan with "Guide by Wire" I'm finding that the rocket is affected by flares even though it is being guiding based on operator feedback thru the view finder as opposed to being in heat lock.
The result is that it will fail to track what I'm pointing at and will instead nose dive at the location of the flare/heat source. Is this correct/expected?
