Hi Ball (oz5699)
About this Plan
Hi-Ball. Free flight power duration model. From Aeromodeller October 1947.
Quote: "As a fitting start to what should be a long series, if pylon models retain their undoubted popularity, we present here one of the most successful diesel models of original design in the 1947 competition season, and the first pylon power model to be featured in our pages. Some idea of this model's performance can be gained from the fact that out of six successive contests the Hi-Ball won five. Anyone who has seen the model performing at the Nationals or at Eaton Bray will understand why.
The standard performance of this fascinating little model is a take-off run of negligible distance followed by a literally vertical corkscrew climb for all of the usual twenty seconds engine run, followed by an amazingly flat glide which keeps the model in the air for well over a two minute average. Strangely enough the original model has never yet caught a thermal, although perhaps this is as well to judge from its best flight to date of three minutes forty-six seconds without such aid. All credit to young designer Pete Neate of the St. Albaus' Cement-Squeezers.
Despite the pylon power-house type of design the model succeeds in achieving a not ungraceful appearance. There is plenty of strength built into the construction, and the original model though scarred is still flying as well as ever. The simple construction is extremely robust and has an additional advantage in that, despite the low drag circular section, it does not require any jigs..."

* 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.
