Our Aero Vodochody "Super Delfins" have upgraded engines (replacing the original engine with a Pratt & Whitney J-60) with increased fuel efficiency and a startling 50% increase in maximum thrust. With its reduced weight and increased power, our L-29s have the same thrust-to-weight ratio as the USAF’s A-10, will do 425 KCAS at sea level with a 12,000 fpm climb rate. Equipped with modern avionics, including UHF radios and GPS, this rugged jet is the perfect low cost training or test platform.
