About this Plan

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..."

Datafile:

ScaleType:
  • Island_X-199_Spectra | help
    see Wikipedia | search Outerzone


    ScaleType: This (oz9154) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Island_X-199_Spectra
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
