Miles Messenger (oz7616)
About this Plan
Miles Messenger. Profile scale model for control line.
Quote: "Ray Malmstrom invites you to build this attractive little point five powered profile control line model of a Miles Messenger.
SHORT of time? Not a lot of space for flying a C/L job ? Yet you would like something new and snappy for that next club meeting. Well, what about carving up some sheet and getting this little craft into the air? Time? Just two evenings and the job's done. Lines? Perfectly at home on anything between 15 and 25 ft. Looks? Well, most scale merchants agree that Mr Miles has an eye for a nice line in aircraft.
The plan and diagrams explain the very simple construction, which is entirely of balsa and ply, but one or two points may need a little emphasis. Dimensions are given for a fuel tank from sheet celluloid, fitted with neoprene tubes. Herewith a tip. Useful tanks can be cut from the celluloid cases that contain tooth-brushes, so why not treat yourself to a new peg-polisher and solve the tank problem in one go?
A word on the alternative tank arrangement shown on the plan Diagram 1. Some of us find an inverted engine a bit of a brute to start, being used to the upright installations. This is easily solved by fitting a 1/2A Mercury stunt tank, as shown in Diagram 1, and by recessing the fuselage blocks about 3/8 in and cutting a slot in the engine mount. Make the tank a tight fit in this recess. Any gaps can be filled in with scrap sheet. All you do, with this installation, is to turn the model upside down and start on your usual settings. When the engine is running, turn the model the right way up.
Finish: Two coats of clear dope lightly rubbed down, and pick out the cabin
in black. Give entire model a coat of fuel proofer. For a really good-looking job, finish with a coat of Starlon plastic enamel, which, incidentally, saves the application of fuel-proofer. Check the CG position from plan. Weight should be 4-1/2 to 4-3/4 oz. The original model is pale blue with maroon lettering.
Flying: Always hold the model by the engine mount when starting and never by the fuselage. The original was flown with the Allbon Dart and ED 0.46, both of which power units gave it a really enjoyable 'sports-flying' performance on 20 to 25 ft lines in calm conditions. How-ever, by altering the location of the mounting holes, almost any 0.5 cc motor can be used. Full size plans overleaf."

* 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.
