The plane was built based on the plan view of the actual aircraft, suitably modified.. the leading edge sweep was reduced and the span was increased (compared to the scale). (the next build will have a better fuse, in any case the bty is housed inside the fuse and accessed by a hatch on the fuse top. The shape of the fuse needs to be changed, which I do in my next build The CG is located on the line joining the points the main wing LE start point Span 24 inches AWU - 250 gms Motor ; 2205. 2200KV, turning a 6X4 prop chopped to 4.5X4 She flies beautifully
