Airframe Kit Options
One of the benefits of building your own aircraft is the ability to equip it exactly as you wish. Van's Aircraft offers a number of options that allow you do this. While many components can be added throughout an aircraft's life, some are best installed during the construction process. Several of these options are listed on the kit order form.
Most of the kit options below may be viewed and ordered from the Accessories Catalog.
Prefabricated SparModels: RV-4, 6/6A; Standard on RV-7/7A, 8/8A, 9/9A,10
The standard spar comes with all the necessary holes drilled, the spar cap strips tapered and the lightening holes removed. The builder must deburr and finish the components, prime, and rivet the spar together; an estimated 40-50 hours of work. The optional Prefabricated spar is completely assembled, gold anodized for corrosion protection and ready to install. Order from Phlogiston Products.
Electric Elevator Trim KitModels: RV-4, 6/6A, 7/7A, 8/8A, 9/9A; Standard on RV-10
Uses the same trim tab as the standard manual trim. A servo motor installed in the elevator replaces the push-pull cable. Kit includes formed metal parts, hardware and instructions. Weight comparable to manual installation. Best ordered and installed during construction of Empennage Kit.
Electric FlapsModels: RV-4, 6/6A; Standard on QuickBuild;
Standard on RV-7/7A, 8/8A, 9/9A, 10
This option eliminates the manual flap handle between the seats (RV-6/6A) or alongside the passenger’s left leg (RV-4). More convenient and adds to useable room. Driven by a small industrial motor/gear unit, the flaps extend/retract in about 8 seconds. All factory prototypes have been converted to electric flaps. Order with the Fuselage Kit.
Manual Aileron TrimModels: RV-3, 4, 6/6A, 7/7A, 8/8A, 9/9A
Aileron trim is not standard on the RVs, but it is recommended. The manual option provides a simple, light and effective way of trimming out minor lateral imbalances due to uneven fuel burn, etc. A small lever is fitted to the base of the control stick (RV-4), between the seats (RV-6/6A), or on the left side panel (RV-7/7A, 8/8A, 9/9A) and displaces the ailerons very slightly through springs connected to the control system. Unnoticeable through the stick. Order with Fuselage Kit. Easily fitted to finished aircraft.
Electric Aileron TrimModels: RV-4, 6/6A, 7/7A, 8/8A, 9/9A, 10
This option controls trim with a small trim tab mounted on the trailing edge of the aileron and powered by a servo motor mounted inside the aileron (RV-4, RV-6/6A). Best installed during construction. Kit includes formed metal parts, hardware and instructions. Cockpit control may be mounted on stick (a "high hat" switch controlling both elevator and aileron trim is popular) or anywhere the builder desires. RV-7/7A, 8/8A, 9A, 10 kits similar to manual trim, with no external tab, but uses servo to drive bias springs. Order with Wing Kit (RV-4, 6/6A) or Fuselage Kit
(RV-7/7A, 8/8A, 9/9A, 10).
