About this Plan

Minotaur. Free flight power contest model.

Quote: "THE original 'Minotaur' so the dictionary tells us, was a 'fabulous monster' of ancient Greek times. This model being both noisy and monstrous (in shape though not in size), though far from fabulous; the name seemed appropriate.

This particular Minotaur, unlike the original Greek beast, was designed as a contest power model for the popular E.D. Bee 1cc diesel. It has proved satisfactory in every way and offers a change as well as a challenge to the larger model. The need for a cumbersome undercarriage is eliminated, and props are saved, by fairing the sprung mono-wheel into the fuselage. The tailplane underfins give a firm three-point stance, and on its first trials the Minotaur left the deck with an ease that startled even the poor designer.

The climb is near-vertical, but it is on the glide that this model really scores, thanks to the wing section, which is from the well-known Swedish Sigiard Isacson series. Ratios of 7 and 8 : 1 in still air are common, and it was not long before the Minotaur had pushed the Ampleforth College club power duration record successively to 7 min. 43 sec. and 10 min. 31 sec, o.o.s. Later the ratio record was also smashed, when the model disappeared into cloud after 9 min. 15 sec. on a 15 sec. engine run. (Ratio 37:1). Needless to say, the occasion was a trimming flight prior to a national competition! The Minotaur was not recovered in time for the event, but when it was found it was discovered to have stayed in the air for 1-1/4 hours. (Work that ratio out!) In addition it had established a new club distance record of 11.7 miles."

* 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.


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.
