Watch the Right Hand Basics #1 online guitar lesson by Cathy Fink from Clawhammer Banjo: Beginner Module 1
Take your time in the early stages of playing clawhammer banjo. A good right hand technique will serve you forever in your playing whereas a sloppy right hand technique will lead to a lack of clarity and precision in your playing. No hurry.
I also suggest that in the beginning, practicing the right hand a few times a day for 5-10 minutes will help you progress more than playing it for 30 minutes at a time.
