Quote: "F-4 PHANTOM. Stand-Off Scale F-4 for a single engine/fan unit. By Pavel Bosak.
The F-4 Phantom has already been modeled several times, with either a pusher propeller or ducted fan unit being used for propulsion. I have built F-4 Phantoms using both of these power systems. In spite of that, I decided to build another Phantom as I consider it to be the most beautiful aircraft ever built. Another reason that induced me to build my latest Phantom is that the development of ducted fan units has shown great improvement since I built my first fan powered Phantom.
This model was originally designed for use with a Boss 602 ducted fan unit but I decided to use a Dynamax unit instead. This change was easy to accomplish. I used a Rossi .81 engine for power, although I think that an O.S. .77 would also be an ideal power choice; it retains all the good in-flight characteristics of its predecessors.
This aircraft flies fast and is capable of performing all the basic aerobatic maneuvers; it is equipped with wing flaps which I use to make shorter take-offs. My model is also fitted with a braking parachute that does slow the landing roll out a bit, but I actually use it more for scale realism and show, it also features another extra: rockets that are capable of being fired electrically. Eight rockets are carried and can be fired at one second intervals.
As can be seen by viewing the plan sheets, this version of the F-4 Phantom is intended for RC'ers who possess a fair amount of scratch building experience and are accomplished pilots. The plan sheets and written text do not cover every detail and construction technique; however, the assembly process is quite conventional and well within the capabilities of any modeler who has built a few aircraft from plans only.
Construction. We will begin with the ducted fan unit. Screw the fan unit to the 5/8 square hardwood mounting beams. These mounting beams are now epoxied between formers F5 and F6. The 1/32 plywood (F9) floor is now glued in place. Install half former F5A between formers F5 and F6 as shown. Fabricate the 1/32 plywood air exhaust. pipe and install it from the fan unit to former F6. The top half of the air exhaust pipe is made from 1/32 plywood strips (see photo)..."

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

ScaleType: This (oz5982) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/McDonnell_Douglas_F-4_Phantom_II
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* 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.
