About this Plan

Dragon Fli. Radio control pattern plane.

Note also later kitted by RC Models.

Quote: "Dragon Fli By Phil Kraft. All-out competition stunt ship by Phil Kraft ­ based on years of experience and testing. Retracts recommended for best performance.

Today, there are several extremely powerful engines with great reliability as well. Therefore, the design trend has been made possible almost entirely by the availability of superior engines.

The Dragon Fli design is a development of the Slik-Fli (oz9685) type fuselage, combined with a newer wing design. Three different airfoils were tried during testing before settling on a 15 per cent section with a maximum camber at about 40 per cent. This low aspect ratio was selected primarily for ease of transportation. It does not appear to have any deficiencies, and may have advantages as far as flight performance is concerned.

The deep fuselage of the Dragon Fli contributes to stability, particularly in rough air. Like anything else, it also has disadvantages, such as in taxiing in strong winds. The plans show retract gear, and there is no question but what this is an absolute necessity for contest flying today. Fliers used to think the effect of retract gear was primarily psychological. However after having flown an airplane with retract gear, I don't think I would enjoy going back to the fixed gear model again, despite the headaches with the less than satisfactory retract gear units that are currently available.

To sum up, the Dragon Fli is a sound design capable of competition performance. Jim Edwards flew one to second place in this year's Nationals, and two others placed in the top 20 qualifiers."

* 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.
