NIEUPORT 11 7/8 scale

NOTE:   The N 17 Full Scale Plans were drawn by Graham Lee upon huge demand from homebuilders.     Graham had never built a prototype, but he scaled up the design based on the time proven construction elements of the 7/8's aircraft.  

 

Designed and prototyped in the spring of 1984, the 7/8 scale Nie. 11 went through a hurried 10 hours of serious test flying before being loaded on a trailer for the trip to Oshkosh. Flight testing included the usual stuff, while I was watching, (and some “unauthorized” activities when I was not.)

 

Loops, spins, Split S and a 4000ft power dive were performed on C-IRCA (do not try this at home folks! Aerobatics NOT recommended! )

 

The 11 can be built with lightweight TUFF wheels and a Rotax 447 in the US Ultralight category. As a registered homebuilt, (or UL in Canada) it can be built in a range of variants including the Ni 17/24/27 and Siemens Shuckert D1.

* Recommended powerplants include the Rotax 503, 447, or VW.

 

Construction: The structure is 6061 tube with pull riveted gussets and bolts. Wings and fuselage are fabric covered. Plans are designed for the first time builder with basic tools.
