About this Plan

DL 5. Radio control stand-off scale model Homebuilt plane. Wingspan 60 in. Scale is 1/5.

Quote: "A minimum home-built aircraft. Following the design of its full-size counterpart, the DL5 is a simple, quick building aircraft for .25-35 engines. By Paul F Denson.

The DL5 is an aircraft proposed by DM Livesey, an English home-built designer. It first appeared as a design in the July-August 1971 issue of Popular Flying which is the journal of the Popular Flying Association, the British equivalent of our United States Experimental Aircraft Association.

A Minimum home-built (quoting Mr Livesey is one that can reduce the building time of from 1500 to 2000 hours by removing the making of jigs, deciphering unnecessarily complex plans, and eliminating the innumerable hours running around looking for specific unobtainable aircraft supplies. And with spruce and birch ply becoming more and more rare, the use of standard marine ply.

What we need is a plane that is easily built, may be constructed in a standard garage, a minimum of tools, no fabric, covering and no welding. All wheels, seats, fuel tanks are to be commercially available, and this aircraft, when completed, will pass through a standard 2 ft 6in door. Don't laugh, more than one wall has been torn down to get a home-built boat or plane out to the light of day. Just ask me, I built a boat in my basement. Oh yes I did and it sailed quite well. It must be trailerable and can be stored in the above mentioned garage.

Our model is 1/5 stand-off scale, well not too far off. We did make modifications which conform to Romney Bukolt's Basic R/C Model Design Parameters as published in Jan '80 RCM in Ken Willard's column. An appropriate engine should be from .25 to .35. Controls are 4-channels; ailerons, throttle, rudder, and elevator.

The only thing that varies from full-scale are the lack of Warren type wing ribs as you can see in the cutaway drawing. The fuselage is a constant section 2 inch tube made up of four longerons. We found this made the fuselage easy to construct but, unlike the full-size plane, we needed room for non-scale servos and a fuel tank in the lower area. To find a place for them, it necessitated removal of the top center longerons from the seat back forward to the fire wall. The 1/8 lite ply sides more than made up for any loss in strength. The plans have been modified to show this change. Flaps were not used due to space limits.

Construction: We have found (and so has RCM's Chuck Cunningham) that the very inexpensive small size knives with the sliplock break-off blade is fantastic for all phases of modeling. They are available for around 75c in most hardware stores.

Fuselage: Cut all formers from the materials indi-cated, It will be necessary at this time to construct the combination of formers F-4 and F-5. They must he tilled top and bottom with 3/16 aircraft ply, leaving the center vacant for the insertion of the 3/36 ply wing tongue... "

ScaleType:
  • NotFound | help

    This is a scale plan, but ScaleType is set as NotFound.

    This happens when we can't find a relevant Wikipedia page to link to. Usually because the type in question is uncommon.

Hi there,
I'm trying to get in touch with Paul Denson regarding the plans for the DL5 aircraft. I am David Livesey's daughter.
Thanks!

Notes

* 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.

Scaling

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.
