For pilots wanting to fly a modern generation aircraft with similar flight characteristics to our popular Freewing 90mm F-22 but at significantly lower operating cost, the Freewing 70mm F-35 is an excellent choice. Having gathered feedback from many customers about Freewing's nine year old F-35, we improved all major components of the aircraft. First, the model is made of EPO instead of EPS foam. Second, it is slightly larger, features a stronger power system, and incorporates a wing spar and detachable wings, compared to the old model which was small, 4s powered, and didn't have a wing spar for its glue-on wings. Third, we relocated the battery hatch to the top of the aircraft to give easy access in a generously sized battery bay to modern receivers, gyros, and flight battery. Say goodbye to frustratingly undersized plastic hatches under the fuselage. Third, the model features a no-glue assembly, and all flying surfaces attach via screws for easy transport, servicing, and replacement.
The all-new 2019 Freewing 70mm F-35 Lightning II also incorporates two important functional improvements. To provide reliable grass operation, this model includes pre-installed electric landing gear with aluminum suspension struts. Oleo mains and a trailing-link nose help absorb the shock of rough landings or taxing through uneven grass. And secondly, the full flying horizontal stabilizers feature an integrated plastic-to-plastic hinge joint that is durable to withstand 100+mph speeds. Older F-35s were known were weak landing gear and weak elevators, so both of these areas were completely redesigned to deliver the level of performance our customers expect from our EDFs in these modern times.
Optimized as a modern 70mm jet trainer, this model is ideal for pilots wanting to step into the world of EDF jets and learn essential skills before they advance into larger aircraft in our 80mm and 90mm series. Learn coordinated turns with the rudders and ailerons, get used to throttle management throughout the aircraft's full acrobatic flight envelope, and practice perfect landings on the suspension struts. One of the advantages of the F-35's 6s power system and larger size is that it uses the same 6s 4000mAh or 6s 5000mAh batteries that our 80mm and 90mm EDFs use, so those batteries can remain in your fleet and be shared across many model aircraft. The F-35's inrunner power system is efficient enough for 4-5 minutes of mixed throttle flight, and powerful enough for fast speeds and confident takeoff from short grass runways. While sporting the outline of the real stealthy F-35, our model is still optimized aerodynamically to land as easily as any of our other recent EDF jets.
The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather, stealth, fifth-generation, multirole combat aircraft, designed for ground-attack and air-superiority missions. It is built by Lockheed Martin and many subcontractors, including Northrop Grumman, Pratt & Whitney, and BAE Systems.
The F-35 has three main models: the conventional takeoff and landing F-35A (CTOL), the short take-off and vertical-landing F-35B (STOVL), and the catapult-assisted take-off but arrested recovery, carrier-based F-35C (CATOBAR). The F-35 descends from the Lockheed Martin X-35, the design that was awarded the Joint Strike Fighter (JSF) program over the competing Boeing X-32.
The United States principally funds F-35 development, with additional funding from other NATO members and close U.S. allies, including the United Kingdom, Italy, Australia, Canada, Norway, Denmark, the Netherlands, and formerly Turkey. These funders generally receive subcontracts to manufacture components for the aircraft; for example, Turkey was the sole supplier of several F-35 parts until its removal from the program in July 2019. Several other countries have ordered, or are considering ordering, the aircraft.
As the largest and most expensive military program ever, the F-35 became the subject of much scrutiny and criticism in the U.S. and in other countries. In 2013 and 2014, critics argued that the plane was "plagued with design flaws", with many blaming the procurement process in which Lockheed was allowed "to design, test, and produce the F-35 all at the same time," instead of identifying and fixing "defects before firing up its production line". By 2014, the program was "$163 billion over budget [and] seven years behind schedule". Critics also contend that the program's high sunk costs and political momentum make it "too big to kill".
The F-35 first flew on 15 December 2006. In July 2015, the United States Marines declared its first squadron of F-35B fighters ready for deployment. However, the DOD-based durability testing indicated the service life of early-production F-35B aircraft is well under the expected 8,000 flight hours, and may be as low as 2,100 flight hours. Lot 9 and later aircraft include design changes but service life testing has yet to occur. The U.S. Air Force declared its first squadron of F-35As ready for deployment in August 2016. The U.S. Navy declared its first F-35Cs ready in February 2019. In 2018, the F-35 made its combat debut with the Israeli Air Force.
The U.S. stated plan is to buy 2,663 F-35s, which will provide the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps in coming decades. Deliveries of the F-35 for the U.S. military are scheduled until 2037 with a projected service life up to 2070.
