Sweet P (oz9622)

About this Plan

SWEET-P. Radio control sport/pylon model for O.S. Max 10 FSR power.

Quote: "The Sweet-P sport pylon airplane was designed with one primary objective in mind - fun! Sweet-P does not meet the needs of any major competition category nor does it represent a major breakthrough in aeronautical technology. It does, however, fill the need for an easy to build, scale looking airplane that is inexpensive to build and operate. It is also easy to transport, and is capable of carrying a standard size radio control system with two servos. Small battery packs and sub-miniature servos are not required.

Sweet-P is a slightly enlarged 1!2A racer designed around the O.S. Max 10 FSR. It was designed primarily for sport aerobatics rather than all-out racing. It uses a nice thick symmetrical airfoil for excellent lift and soft stall characteristics. The O.S. Max .10 FSR has plenty of power to provide good vertical performance. This airplane was also designed to be as simple as possible to build and maintain. Only two channels were used on the prototype (aileron and elevator). However, a third servo for throttle could be added if sub-miniature servos were used. As a matter of convenience, the aileron servo was installed in the fuselage. While one might think trim changes would occur due to the wing shifting, a snug fitting wing will eliminate this. In the two seasons of flying the Sweet-P, I have not encountered any problems in trim changes with this aileron set-up.

Don't let the wing be a stumbling block. It can be built in a conventional manner (balsa ribs and spars) if foam cutting equipment is not available. However, a foam core sure makes for a rigid wing that is light in weight..."
