Gst on rcm basis for trust

A trust is registered under the GST act. Trust is carrying on the business of organizing events such as Car race, bike race etc. All these events are sponsored by the persons registered under GST Act. The trust is also collecting entry fees from the participants. 

Is the trust liable to pay GST on RCM basis? Are there any Notifications or circulars related to the same issue. Is there any better option other than showing it under RCM basis? Kindly help me out with this Issue.
