About this Plan

Gran Zot - FAI class A2 competition glider.

Quote: "Carlo Varetto's A/2 glider GRAN ZOT designed for still air conditions...

WHEN COMPETITION FLYING, conditions can naturally vary enormously from contest to contest, or even during a particular event, so a top-class, all-weather glider is an obvious requirement. Unfortunately, such a machine does not, and cannot, exist as it would merely be a compromise. However, the picture is not as grim as it first appears, as competitors are allowed a total of three gliders per contest, so different conditions can be met with the appropriate model. With this 'specialisation' in mind, Gratz Zot was designed - its purpose being to fly in calm or 'dead' air when there is an absence of thermal activity, such as occurs early in the morning or late in the evening. Under such conditions, this model has the potential for achieving the magical 180 second maximum flight. Conversely of course, it cannot be expected to behave so well in blustery weather.

The designer has considerable experience of top-line flying, having placed eleventh at the '69 Free Flight World Championships, and he has again qualified to represent Italy at the forthcoming Champs. In 1968 he won the Italian Championships title, finding Gran Zot to be ideal for this event which was held over two days, the first two flights occurring in the Saturday afternoon with the remaining three on the Sunday morning. This of course meant that for the second and third flights, Gran Zot was really in its element! At Wiener Neustadt, Carlo intended to use this model in the fly-off but unfortunately never had the opportunity, as a line tangle during the fourth round spoilt his otherwise perfect score - his only consolation being in Carlo's words 'a real champion (Elton Drew) won, and not an outsider'.

The model is 'typically Italian' with its multi-spar, multi-braced wing producing an extremely rigid, warp resistant structure, particularly necessary in his high-humidity native country. It should be understood that this is not a beginners model, although it is not really as complex as it looks when approached in a logical manner just rather more work!

The fuselage used by Carlo, with its tapered, detachable rear boom and aluminium nose cone does of course necessitate access to workshop facilities, but if this is beyond your means, an alternative 'British' fuselage is drawn based upon a glass fibre rod - not surprisingly as it was provided by Tony Cordes of 'Ronytube' fame..."

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.
