I’m hesitant to recommend an autopilot for a skill you don’t have
B2N2, the problem is a helicopter such as a Robbie has no natural stability such as a fixed wing, the machine is balanced on the head of a pin, a stabilisation system (SAS) endows the helicopter with fixed wing like stability, but costs $$$. Eases the work load no end, but of course you need the skills should it take a holiday.
