The Lightning XS kit has a redesigned forward fuselage structure that gives the builder the option to choose engines up to 180 hp. Taller landing gear for bigger props, bigger brakes, and 20 gallon fuel tanks are among some of the features of this new kit. It contains much of the same stuff as the classic but is only firewall aft. Then you choose from a list of firewall forward packages we offer to go with it.
These include the Titan XIO340 180hp, legacy piston engines O200-O320, 115 hp to 160 hp, UL Power UL520is 180 to 200 hp engines. If you have a different engine in mind then you can save the money on the firewall forward and just buy what you need.
