Q: Does the kit purchased on the receipt have to be the same kit that is submitted?
A: The purchase can be anything, not necessarily of the entrant model(s). In short, as long as the receipt is for purchases made within 12 months, it satisfies this requirement. The purchases help to defray some of the immense costs of the event.
Q: Does contest kit have to be Airfix only brand?
A: All entries in the 2020 mini-Airfix Cup must be of Airfix/HiPM/FROG brands only.
