These new resin wheels are a huge upgrade to the soon to the Airfix Mosquito in 1/24th scale. They represent the late, dual brake style wheel fitted to all but the early B. Mk IVs and NF IIs, and feature detailed and accurate tread pattern, hub detail and tire data. The Airfix kit is very nice, but the wheels are poor, with monster truck style tread on the vinyl tires. A quick and easy upgrade.
