Update: Went back yesterday for another lesson, determined to get it right. Flew straight and level, managed to relax alot more and was allowed to start our descent back to the airfield.
My hovering was atrocious, all over the place really, but was happy I made some progress flying. And no sickness. Going to stick at it, and thank you for all your encouraging comments it helped alot.
Any tips on hovering would be great, had the collective and pedals down but seem to have got worse keeping the cyclic steady. Seems almost impossible at the moment but I'll get there one day!
