ThunderQuest is an FLL qualifying event that Team 217 has annually held at Henry Ford II High School since 2002. It is one of the largest FLL competitions in Michigan, with over 50 Lego League Teams showing up to compete each year. The ThunderChickens are responsible for planning, decorating, setting up, judging, and selling concessions for the event. Members of the team also make decorations and construct the LEGO field elements, then show up on the day of the competition ready to give their all while volunteering in more typical areas, such as queuing, field reset, and refereeing.

In 2019, the ThunderChickens widened their outreach to young FIRST students by expanding ThunderQuest to the FTC level of competition. This new offseason event took place in May and was co-hosted with Team 226, the Hammerheads. 14 FTC teams participated in the event in its first year, and the ThunderChickens set up for the event and did the majority of the volunteering, including reffing, judging, queueing, and field reset. In addition, the team brought their 2019 world champion robot, Alexa, for the kids to look at to see what was in store for their future in FIRST. Members and mentors of 217 were available to provide guidance or answer general questions.
