About this Plan

Handley Page Sayer Monoplane HP22. A 33 inch wingspan indoor scale model for Cox TD .010 and two function micro RC.

Quote: "David Boddington invites you to build this little indoor or outdoor scale model.

FOR THIS MODEL you have a choice of two sizes, the one shown here or to increase the dimension by 8% ie ask the photo print shop to take copies at 108%. The original model was flown at the smaller size and proved, with a weight of 7ozs to have ample power. Longitudinal stability was marginal but the flight control was sufficient to carry out a flight in Olympia and won the Handley Page Association trophy. The contest flight was carried out on the Thursday before the MEE and the second 108%. model was built and put on display by the following Thursday.

By careful selection of wood, a revised tailplane (larger but lighter) and some judicious lightening holes in the formers and the sheet structure above the wings there was no weight increase and the 7 oz figure was maintained. I put a 1/16 sheet floor below the engine and put a hole in the lower section of F3 so that the battery, a 125mAh pack, could project to F2.

Whether you build the smaller or larger version you must keep the radio as far forward as possible - and the rear end as light as possible. I used the Hitec Focus micro servos and receiver (27mgs) and a Cox TD 010 engine, they all performed excellently indoors and out. The 125mAh battery was no problem as weight was needed in the nose, no switch was fitted, the battery being plugged direct into the receiver and then the wings secured..."
