Spectra 2. Radio control scale seaplane model.
Quote: "RCM is proud to present the Spectra II, the most beautiful and unique R/C amphibian design ever published by the model press. As presented on the following pages, the Spectra is a 1/6th scale radio controlled engineering test model built by Island Aircraft Corporation, 10 Granada Avenue, Merritt Island, Florida 32952, as their engineering test model for the full scale prototype. The fully proportional ailerons, rudder, elevator, throttle and flap controls closely correspond to the full scale vehicle.
The full size Spectra is a bold design approach that yields exceptional performance coupled with startling good looks in a completely new amphibian aircraft concept. The secret to the Spectra's performance is in its unique configuration that eliminates the drag penalties paid by amphibians in the past. This new configuration is in the patent pending stage now by Island Aircraft Corporation and will usher in a new dimension in airplane versatility, performance and safety.
RCM readers will note the full scale Spectra shown in one of the photographs. This is Island Aircraft Corporation's research test vehicle and, except for some nacelle reshaping and relocation of the pitot boom, represents Spectra's final configuration. Thus the model as presented here is virtually fully scale.
With regard to some interesting notes on the design features of the full scale Spectra, the engine location finally chosen is a result of an exhaustive preliminary design study to find a propeller location that avoided problems that most previous single engined propellor driven amphibians have had..."
