(Aus. 80). Sander Veenstra a prolific designer of ultralight aircraft began with the Bluebird a single seat, high wing pusher aircraft. He then developed the Thermite (inverted tail), a sleeker aircraft. The SV8 Bandit was a sleek motorglider with an upright V-tail. He preferred the Robin EC 25PS 244 cc engines for his craft. The pictured aircraft has a wing span 26’3” and empty weight of 245 lbs. It was offered ready to fly and appears diminutive in size. Unfortunately, I cannot confirm the designation for the pictured aircraft. SV Aircraft Pty Ltd.
