Check the season
Read your event in the 2027 Division B manual and check corrections before choosing a design.
Plan before buying
Use the suggested practice kit as a starting point. Match every competition item to the current rules.
Keep the evidence
Record repeated trials, failures and one change to try next. A best run alone does not show readiness.

The official rules desk
These guides are club preparation aids. Exact dimensions, allowed materials, required equipment and scoring come from the current manual, corrections and applicable tournament instructions. Older diagrams and kits may use different limits.
