  • Page 4 STEP A TIGHTENING AND RE-SHRINKING THE COVERING Open your kit slowly and take care not to damage any parts of the kit. Remove all parts from their plastic protective covers for inspection. Before doing any assembly or installation of any decals it is very important to re-shrink or re- tighten the already applied Ultracote covering.
  • Page 5 STEP C WING ASSEMBLY 1) Locate the pre cut hinge slots in the wing and aileron. The model comes with CA style hinges pre installed, but not glued into the control surfaces. If you wish to use the CA hinges we recommend adding additional hinges to each surface and use thin foam safe CA when gluing in hinges.
  • Page 6 4) When setting up the servo linkage, we recommend using 4-40 rod with a silver solder clevis. It is very important to have all control linkages 90 degrees to the control surface and servo arm. If more throw is required then the silver solder clevis will enable, then we recommend using a du-bro swivel ball link at the servo arm for more movement.
  • Page 7 STEP D STAB AND ELEVATOR ASSEMBLY 1) Locate the pre cut hinge slots in the stab and elevator. The model comes with CA style hinges pre installed, but not glued into the control surfaces. If you wish to use the CA hinges we recommend adding hinges to each surface and sue thin foam safe CA when gluing in hinges.
  • Page 8 5) It is best to have the linkage as far in on the servo arm as possible and as far away from the control surface as possible. If you are setting up the plane for 3D style flying. We recommend using larger after market servo arms. It is important not to be closer then 1” from the control surface with your control horn.

NOTE: We recommend using metal/rubber washer to secure bolt. 5) Due to shipping and packaging, you may have a fine haze on the beautifully painted cowl.
  • Page 14 STEP N FLYING We believe the Extra 330L will be one of the finest flying airplanes you will ever fly. The 330L has no bad habits and very slow speed stall characteristics. Inverted flight is nearly hands off and knife edge flight takes little or no mixing to remain straight and true.
