About this Plan
Celeritas. Free flight power deisgn for Allbon Dart.
Quote: "Celeritas is designed round the Allbon Dart, a treasured possession of contributor T. Strassberger from Jugoslavia. It follows conventional lines, and indeed should be a very suitable small contest model for the novice to attempt. It is important, however, to keep to prescribed weight. Bare weight of complete job, with motor but without ballast, is 105g, a further 30g (just over an oz) must be added where shown, bringing the flying weight up to 135g, about 41oz. By thus keeping weight well down, and pylon fairly high, a good degree of pendulum stability is achieved.
Normal flight pattern gives a circling climb for 17-19 sec, attaining about 450 feet or more, which will then normally result in a time of 210 - 240 seconds. It is worth making the special propeller that designer offers as this gives it that little extra urge. However, lazy builders may prefer a similar commercial pattern, in which case they must be content with slightly less performance."
Quote: "Normally plans in the Annual were presented as a line drawing with no further comment or information. The Celeritas was different, a small write up and it was then going on to be a plan offered on the plans service. A distinction indeed for this small pylon contest model by T. Strassberger from Jugoslavia... I have traced this design using this TurboCAD and offer it here."
Note this plan is a 2-colour 600dpi bitmap PDF, reduced down from hogal's vector tracing. For the original hogal tracing (probably shows more detail) see supplementary file.

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
