NIEUPORT 11 7/8 scale


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.
