One highly enjoyable aspect of writing this blog is waking up in the morning to emails from France, announcing some exciting developments for those who love small aircraft. Fabrice Tummers from Luxembourg Special Aerotechnics (LSA) and Anne Lavrand from Electravia alerted your editor to a cooperative venture in which they swapped out the original Eck/Geiger motor/controller and Helix propeller combination  (with which the airplane set a class speed record) on LSA’s MC-30e Luciole (Firefly) for an Electravia power package. Since many of the Michel Colomban-designed MC-30s are powered by a Briggs & Stratton V-twin that produces about 26 horsepower, the new electric motor setup provides a great opportunity to compare electric and internal combustion performance. It should be a fair …

Soullier’s MC-30 Luciole (Firefly) had a royal Sponsor, His Serene Highness Prince Albert II of Monaco observing while Jean-Luc flew a 15/25 kilometer (9.3/15.5 miles) straight-line course out and return at 135 kilometers per hour (83.7 mph), winning the RAL1E subclass speed record for microlights. Several subclasses exist for one and two-seat electric microlights – few of which have recognized records, and thereby becoming an opportunity for early adapters of battery-powered, fuel cell or hybrid flight.  These “empty” subclasses are a golden opportunity for those willing to provide …
