Hells Belle (oz1675)
About this Plan
Hells Belle. Free flight gas model. This is a modern redrawn plan in PDFvector format, of the original plan by Vic Smeed. From August 1951 Aeromodeller.
Quote: "Purists, look the other way! Hell's Belle is a strictly functional design in which everything has been sacrificed on the altars of Performance and Durability. With this job, which recognizes no loading or cross-section rules, the fuselage is regarded as merely a means to secure motor, wing and tail in correct relationship, and to provide a little side area here and there. The result is a little short on looks but quite long on flyability, and the Belle's slow, stately flight has a peculiar grace
of its own ...Hell's Belle was designed to incorporate all the lessons learned in two seasons with the earlier models, and features such things as low wingloading (under 4 ozs. per sq. ft., or about 2.7 ounces. per sq. ft. of total area), low power-loading (7.5 ounces. per c.c.), ruggedness and easy trimming ...The flying speed of the Belle is astonishingly slow, both in the glide and under power, although the climb is a tight, vertical spiral. Trimming is easy, and despite the low all-up weight, the job has shown itself capable of taking rougher handling than the average model. The fuselage is almost indestructible. Construction is conventional except that only one fuselage frame is required, and that almost the whole model is built from quite soft balsa - soft enough to retain easily the imprint of a finger nail (M.H.N. 13 or 14). If a larger motor than the original's Elfin 1.8 is to be used, there is no objection to a slightly harder grade of balsa being employed, although the prototype proved itself adequately strong... SIZES AND PRICES FOR THE TRIO: - 60in HELL'S BELLE 5/- (Pet 438) 1.8cc to 2.5cc; 50in HARPIE 4/- (Pet 439) 1cc to 1.5cc; 40in HUZZIE 3/- (Pet 440) motors up to 1cc (ideal for the 'Dart')"

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.
