At the heart of this spine-tingling performance is the phenomenal power of E-flite’s BL15 3200Kv brushless ducted fan motor mated to an E-flite Delta-V™ 15 ducted fan. The unique flight characteristics of such vehicles necessitate a design environment that is able to model and simulate the flight dynamics of ducted fan vehicles accurately. Shop online and save!. I would be very skeptical of the increased thrust claim - both efficiency and thrust of the E-Fan ducted fans are lower than what a well-designed propeller can offer. Then it occurred to me, that the genius Burt Rutan had already designed such an aircraft. The hybrid variant uses regular gasoline or diesel fuel with an extended range of 250+ miles.
