The Aero Vodochody L-39 Albatros is one of those airplanes that looks “right.” It has great proportions and all of its shapes seem to meld together. The full-scale Czech trainer and light attack aircraft has been around since the 1960s. Thousands of L-39s are still flying in the hands of air forces and private owners around the world and modern variants of the L-39 are being developed and produced today. The Flyzone L-39 is an updated version of the popular ElectriFly foamie introduced in 2008. The new L-39 has a larger, more-powerful brushless motor, improved air ducting, and a high-visibility paint job. It is available only as a receiver-ready (Rx-R) kit with preinstalled electronics.
