The Wiki:

The PZL M-15 was a jet-powered biplane manufactured by WSK PZL-Mielec in Poland for Soviet agricultural aviation. For its strange looks and noisy engine it was nicknamed Belphegor, after the noisy demon. The jet aircraft was not economical, and production ceased in 1981 after 175 aircraft were built; it was only used in the USSR. The PZL M-15 is believed to be the world's only jet agricultural plane (e.g., the world's only jet cropduster), the world's only jet biplane and the world's slowest jet, at least as far as aircraft that have been put in mass production.

Standard Flight Controls; VTOL for Flaps
-She requires flap and full trim for flight. This is just such a weird design i had a hard time with the balance.

As Always:
The weirdness continues. This is the weirdest thing I have ever seen, but it was fun to build. Still thinking another one or two in the series, we will see. Stay tuned for 20K special and maybe a challenge or two!! As always, please let me know if you have any suggestions for improvement or a vehicle you would like to see recreated. Thank you for stopping by to look and enjoy your flight!!
