"when learning to fly, RT is the most nervewracking bit"
Arrrrrrgh. Talking. In English. On a radio. How hard is that? Harder/scarier than not crashing in a crosswind?
FNG - try hovering AND talking
When your workload is high and you're concentrating on flying the thing, then speech is the first thing that goes out of the window so finding RT difficult ain't surprising or unusual.
