Check with your instructor first before leading with the thumb button when trimming cyclic forces
Leading with the thumb is the exact opposite to what I was taught as it burns out trim motors due to the much higher workload they are subject too in overcoming the cyclic forces.
I think you will be shown to position the cylic first then trim out.
After a short period of time you'll be doing it without thinking about it.
Call the Aeropower boys they have around eight 500's I think and they would be more than happy to yarn with you about it
