Big Lift (oz4923)
About this Plan
Big Lift. Radio control model. Large model for glider towing. Discontinued kit from Multiplex.
Quote: "The Multiplex Big Lift is a hard-working 'workhorse' aeroplane which has earned immense popularity throughout the world because of its versatility, its robust structure, and its good-natured handling. Big Lift makes the perfect trainer, an ideal glider tug, a capacious parachute dropping platform, and is also hard to beat as a pleasant mannered powered model for a gentle Sunday afternoon."
Quote: "Notes: The print size of the sheet files is 102 x 72 cm. / 40.158 x 28,348 inch. The print size of the manual and 'ribs outer wing' file is A4 / 29.7 x 21 cm. / 8,263 x 11,68 inch. The building manual tells to build the outer wing parts separately and glue them to the root wing parts. Of course it's more wise to build each wing as one part with spars running from root to tip. The 5 mm. bottom plate of the fuselage is very thick... 3 mm. is enough. The Big Lift flies fine with a .60 / 10 cc two-stroke or a .80 / 13 cc fourstroke engine, at a weight of 6 kg. When the Big Lift will be used for towing gliders, a bigger engine should be mounted. Suggested throws: elevator = 25 mm or 18°. Rudder = 30mm or 20°. + 40% exponential."

That happens sometimes. You can help us fix it.

User commentsHi Steve and Mary. Send you a picture of my Big Lift of Multiplex [pic 007]. Added a little modification in vertical stab and add Fowler flaps for more slow landings. I hope like this. Greetings from Colombia.

* 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.
