      <description><![CDATA[This is a simple indoor model with landing gear designed and kitted by JASCO (Junior Aeronautical Supply Company) sometime in the 1950s before JASCO became JETCO.

You may recognize similarities between this model and the Rogue R.O.G. kitted by Midwest Products Company many years later.

I used a laminated &quot;fan&quot; propeller made from 1/16&quot; by 1/4&quot; balsa sticks in lieu of a plastic prop.

I recommend making the motor stick from 3/32&quot; thick basswood instead of the hard balsa called out on the drawing to prevent the wire wing clips from gouging the wood.]]></description>

Fuselage sheet - A4
Wing &amp; tail sheet - A4

Both as PDF

The in-flight snap is courtesy of Andy Blackburn.

This was drawn as a bit of a joke for the Trinity Beginners' No-Cal run by Dave King but it seems to have turned into something viable so here it is.

With the suggested airscrew &amp; motor the model conforms to the original Trinity rules and will turn in flights around 30s.  This means it won’t stand an earthly of troubling the podium in any sort of duration contest, but it is good for a giggle.  Even better, it will ROG; albeit more like a startled sparrow than an aeroplane.  With a balsa airscrew and a longer, thinner motor you should get some decently long flights out of it.

A crayon finish is recommended as more in keeping with the “Beginners” ethos of the project. :)

The odd 11” span of this one is simply to allow for easy printing as it can be fitted very neatly on two A4 sheets and A4 printers are more common at home than A3.]]></description>
