Want an nice upgrade to any 1/48 Boulton Paul Defiant? Step right up to the new Quickboost Defiant Mk.I undercarriage set that provides a beautiful replacement to what is supplied in your kit. The parts are packaged in the standard Quickboost re-closable packaging with a paper stiffener along with the description card. There are no instructions. These parts are specific to fit the Airfix accurate and highly detailed 1/48 Boulton Paul Defiant Mk.I injected plastic kit. They may also work for the older limited run Classic Airframes kits (471, 481, and 482) that were introduced in 1995.
Quickboost has molded the undercarriage set perfectly in light grey resin with no apparent bubbles. The undercarriage set detail is an improvement over what is provided in the kit providing more of a 3-dimensional aspect to the doors.
Make sure you consult your photographs to get the correct geometry for all six parts. I found some useful pics by Ron Patterson at:
