You might be able to guess by the number of pictures of this one, that it is
one of my favourites. The kit is manufactured by Ilsan and
it's a semi scale model of a world famous aerobatic aircraft
manufactured by Walter Extra in Germany.
It was powered by an OS91FX and an in cowl 'pitts' type
silencer which was noisy but gave it enough "oomph"
to go vertical forever, mmm... great fun, perhaps a little
too powerful. Too noisy for the BMAC
field, so I could only fly it at RAF Odiham.
It was recovered a little while back and re-engined with
a YS63FS. The YS63 isn't as powerful as the OS91FX but it
still hauls it limitless vertical, it's lighter and is much
quieter, which allows me to fly it again at the BMAC
I liked it sooooooo much I bought myself another one, in
case I loose this one.
(yet to be built).
