Handley Page HP 42 Plan


Designed by Ken Williams. This scale model of the 1930s airliner will take off and fly easily on four low-cost motors with gearboxes. Construction is from readily available materials but there are so many parts! 4 x A0 plan sheets.

Full Description

This Ken Williams designed plan shows how to build a 94” (2390mm) wingspan RC scale model of the pre-war Handley Page H.P.42 civil airliner – possibly one of the most beautiful aeroplanes ever to fly. But if you’re looking for a quick, easy model to build then look away now because the big 4-sheet plan shows that you’ll need extensive modelling experience and a lot of time to make the hundreds of parts in both wood and metal required to complete the model.

Handley Page H.P.42 aircraft plied the Empire routes between Britain, Europe and Africa for a decade between 1930 and 1939. Used almost exclusively by royalty and the rich and famous passengers travelled in luxurious pullman style cabins whilst being served the best in food and fine wines. Cruising at around 6000 feet at less than 100 mph, the journey to South Africa could take up to a week, with night stops at the best hotels along the route. Despite the dangers of aviation in those pioneering years, H.P.42’s were involved in no serious accidents during their service with Imperial Airways and there were no fatalities, a commercial aviation record that still stands today. Only eight H.P.42’s were built. One was destroyed in a fire in 1937, and the rest were impressed by the War Department at the start of WWII for use by the RAF. By the end of 1941 all had been destroyed in accidents, so we will never see one of these majestic aircraft in the skies again. Or will we? A group called Team Merlin, who once built a replica Vickers Vimy bomber now propose to build a full-size flying replica H.P.42. What a sight that would be.

The model is of conventional wood construction, with additional metalwork needed to fabricate rigging parts and undercarriage. The plan shows options for installing i/c or electric motors.
