About this Plan
Hi Fin '64. Single channel radio control model. For .19 to .35 power. Harrison Morgan's Hi-Fin from Model Airplane News issue 03-65.
Quote: "Hi-Fin was completed early in 1964 and entered in six contests during that contest season. It won five first places and one close second. Weather conditions varied widely from no wind at all at the New England R/C Championships, moderate winds at the Lids and Littleton NH, to high winds at Endicott and Rochester, NY.
Hi-Fin is basically designed with more built-in stability than the average hot rudder-only plane. It handles well both on the ground and in the air. How hot it will be, depends directly on how much you are willing to bend the rudder. Therefore everyone from the sport flyer to the contest flyer should find this airplane interesting.
The plans show installations for both .19 and .35 engines. All of the contests entered were flown with a Fox .25 with the exception of Rochester, NY where a K&B .35 (plugged down) was used for power. A .19 to .25 engine is all you will need even on hard-top runways. The .35 will make for more positive ROGs from grass strip. If you are of the rudder-only school that believes that you can just glide around and .not attempt maneuvers, you will find a .15 engine satisfactory, and you will also be better off with a glider type airplane as the high aspect ratio is more suited for this style of flight.
Hi-Fin is designed for multi equipment permitted in Class I by the new AMA rules. For an escapement airplane to be highly maneuverable, the tail moment should be rather short and the rudder must be aerodynamically balanced..."

* 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.
